Geriforte

Feroze Mahmood, MD

Removing societal stereotypes about aging and helping older adults reject those notions of aging is another way to promote health and life expectancy among the elderly herbs contraindicated for pregnancy discount 100 mg geriforte otc. Unfortunately exotic herbals lexington ky discount geriforte 100mg without prescription, racism is a further concern for minority elderly already suffering from ageism rm herbals 100 mg geriforte with visa. Older adults who are African American herbs pictures order 100mg geriforte, Mexican American herbs chambers generic geriforte 100mg online, and Asian American experience psychological problems that are often associated with discrimination by the White majority (Youdin herbs list buy cheapest geriforte and geriforte, 2016). Ethnic minorities are also more likely to become sick, but less likely to receive medical intervention. Older, minority women can face ageism, racism, and sexism, often referred to as triple jeopardy (Hinze, Lin, & Andersson, 2012), which can adversely affect their life in late adulthood. Poverty rates: According to Quinn and Cahill (2016), the poverty rate for older adults varies based on gender, marital status, race, and age. Women aged 65 or older were 70% more likely to be poor than men, and older women aged 80 and above have higher levels of poverty than those younger. Married couples are less likely to be poor than nonmarried men and women, and poverty is more prevalent among older racial minorities. In 2017, of those 65 years of age and older, approximately 72% of men and 48% of women lived with their spouse or partner (Administration on Aging, 2017). Between 1900 and 1990 the number of older adults living alone increased, most likely due to improvements in health and longevity during this time (see Figure 9. Since 1990 the number of older adults living alone has declined, because of older women more likely to be living with their spouse or children (Stepler, 2016c). Older women are more likely to be unmarried, living with children, with other relatives or non-relatives. Older men are more likely to be living alone than they were in 1990, although older men are more likely to reside with their spouse. The rise in divorce among those in late adulthood, along with the drop-in remarriage rate, has resulted in slightly more older men living alone today than in the past (Stepler, 2016c). According to a Pew Research Center Survey, only 33% of those living alone reported they were living comfortably, while nearly 49% of those living with others said they were living comfortably. Similarly, 12% of those living alone, but only 5% of those living with others, reported that they lacked money for basic needs (Stepler, 2016d). No, but according to the Pew Research Center, there has been an increase in the number of families living in multigenerational housing; that is three generations living Source together than in previous generations (Cohn & Passel, 2018). In 2016, a record 64 million Americans, or 20% of the population, lived in a house with at least two adult generations. However, ethnic differences are noted in the percentage of multigenerational households with Hispanic (27%), Black (26%), and Asian (29%) families living together in greater numbers than White families (16%). Consequently, the majority of older adults wish to live independently for as long as they are able. According to Erber and Szuchman (2015), the majority of those in late adulthood remain in the same location, and often in the same house, where they lived before retiring. Although some younger late adults (65-74 years) may relocate to warmer climates, once they are older (75-84 years) they often return to their home states to be closer to adult children (Stoller & Longino, 2001). Despite the previous trends, however, the recent housing crisis has kept those in late adulthood in their current suburban locations because they are unable to sell their homes (Erber & Szuchman, 2015). However, as individuals increase in age the percentage of those living in institutions, such as a nursing home, also increases. Specifically: 1% of those 65-74, 3% of those 75-84, and 10% of those 85 years and older lived in an institution in 2015. Due to the increasing number of baby boomers reaching late adulthood, the number of people who will depend on long-term care is expected to rise from 12 million in 2010 to 27 million in 2050 413 (United States Senate Commission on Long-Term Care, 2013). To meet this higher demand for services, a focus on the least restrictive care alternatives has resulted in a shift toward home and community-based care instead of placement in a nursing home (Gatz et al. Those in late adulthood need to achieve both the acceptance of their life and the inevitability of their death (Barker, 2016). This acceptance will lead to integrity, but if elders are unable to achieve this acceptance, they may experience despair. Bitterness and resentments in relationships and life events can lead one to despair at the end of life. According to Erikson (1982), successful completion of this stage leads to wisdom in late life. The current focus on aging well by keeping healthy and active, helps to promote integrity. There are many avenues for those in late adulthood to remain vital members of society, and they will be explored next. Staying Active: Many older adults want to remain active and work toward replacing opportunities lost with Figure 9. Not surprisingly, more positive views on aging and greater health are noted with those who keep active than those who isolate themselves and disengage with others. Community, faith-based, and volunteer organizations can all provide those in late adulthood with opportunities to remain active and maintain social Source networks. Generativity in Late Adulthood Research suggests that generativity is not just a concern for midlife adults, but for many elders, concerns about future generations continue into late adulthood. Additionally, they are volunteering in their community, and raising their grandchildren in greater numbers. Hooyman and Kiyak (2011) found that religious organizations are the primary settings for encouraging and providing opportunities to volunteer. Hospitals and environmental groups also provide volunteer opportunities for older adults. While volunteering peaks in middle adulthood, it continues to remain high among adults in their 60s, with about 40% engaging in volunteerism (Hooyman & Kiyak, 2011). While the number of older adults volunteering their time does decline with age, the number of hours older adults volunteer does not show much decline until they are in their late 70s (Hendricks & Cutler, 2004). African-American older adults volunteer at higher levels than other ethnic groups (Taylor, Chatters, & Leving, 2004). Taylor and colleagues attribute this to the higher involvement in religious organizations by older African-Americans. Older adults who volunteer experience more social contact, which has been linked to higher rates of life satisfaction, and lower rates of depression and anxiety (Pilkington, Windsor, & Crisp, 2012). Longitudinal research also finds a strong link between health in later adulthood and volunteering (Kahana, Bhatta, Lovegreen, Kahana, & Midlarsky, 2013). Lee and colleagues found that even among the oldest-old, Source the death rate of those who volunteer is half that of non-volunteers (Lee, Steinman, & Tan, 2011). However, older adults who volunteer may already be healthier, which is why they can volunteer compared to their less heathy age mates. New opportunities exist for older adults to serve as virtual volunteers by dialoguing online with others from around the world and sharing their support, interests, and expertise. Virtual volunteering is available to those who cannot engage in face-to-face interactions, and it opens-up a new world of possibilities and ways to connect, maintain identity, and be productive. Grandparents Raising Grandchildren: According to the 2014 American Community Survey (U. Older adults have far less 415 energy, and often the reason why they are now acting Figure 9. While most grandparents state they gain great joy from raising their grandchildren, they also face greater financial, health, education, and housing challenges that often derail their retirement plans than Source do grandparents who do not have primary responsibility for raising their grandchildren. As individuals age, changes occur in these social networks, and the Convoy Model of Social Relations and Socioemotional Selectivity Theory address these changes (Wrzus, Hanel, Wagner, & Neyer, 2013). Both theories indicate that less close relationships will decrease as one ages, while close relationships will persist. The Convoy Model of Social Relations suggests that the social connections that people accumulate differ in levels of closeness and are held together by exchanges in social support (Antonucci, 2001; Kahn & Antonucci, 1980). According to the Convoy Model, relationships with a spouse and family members, people in the innermost circle of the convoy, should remain stable throughout the lifespan. In contrast, coworkers, neighbors, and acquaintances, people in the periphery of the convoy, should be less stable. These peripheral relationships may end due to changes in jobs, social roles, location, or other life events. These relationships are more vulnerable to changing situations than family relationships. Therefore, the frequency, type, and reciprocity of the social exchanges with peripheral relationships decrease with age. The Socioemotional Selectivity Theory focuses on changes in motivation for actively seeking social contact with others (Carstensen, 1993; Carstensen, Isaacowitz & Charles, 1999). This theory proposes that with increasing age, our motivational goals change based on how much time one has left to live. Rather than focusing on acquiring information from many diverse social relationships, as noted with adolescents and young adults, older adults focus on the emotional aspects of relationships. To optimize the experience of positive affect, older adults actively restrict their social life to prioritize time spent with emotionally close significant others. In line with this theory, older marriages are found to be characterized by enhanced positive and reduced negative interactions and older partners show more affectionate behavior during conflict discussions than do middle-aged partners (Carstensen, Gottman, & Levenson, 1995). Research showing that older adults have smaller networks compared to young adults, and tend to avoid negative interactions, also supports this theory. There is more support going from the older parent to the younger adult children than in the other direction (Fingerman & Birditt, 2011). In addition to providing for their own children, many elders are raising their grandchildren. Consistent with socioemotional selectivity theory, older adults seek, and are helped by, their adult children providing emotional support (Lang & Schutze, 2002). They found that the older parents of adult children who provided emotional support, such as showing tenderness toward their parent, cheering the parent up when he or she was sad, tended to report greater life satisfaction. In contrast, older adults whose children provided informational support, such as providing advice to the parent, reported less life satisfaction. Lang and Schutze found that older adults wanted their relationship with their children to be more emotionally meaningful. Daughters and adult children who were younger, tended to provide such support more than sons and adult children who were older. Friendships: Friendships are not formed in order to enhance status or careers, and may be based purely on a sense of connection or the enjoyment of being together. Being able to talk with friends and rely on others is very important during this stage of life. Bookwala, Marshall, and Manning (2014) found that the availability of a friend played a significant role in protecting the health from the impact of widowhood. Specifically, those who became widowed and had a friend as a confidante, reported significantly lower somatic depressive symptoms, better self-rated health, and fewer sick days in bed than those who reported not having a friend as a confidante. In contrast, having a family member as a confidante did not provide health protection for those recently widowed. Loneliness or Solitude: Loneliness is the discrepancy between the social contact a person has and the contacts a person wants (Brehm, Miller, Perlman, & Campbell, 2002). Women tend to experience loneliness due to social isolation; men from emotional isolation. Loneliness can be accompanied by a lack of self-worth, impatience, desperation, and depression. Novotney (2019) reviewed the research on loneliness and social isolation and found that loneliness was linked to a 40% 417 increase in a risk for dementia and a 30% increase in the risk of stroke or coronary heart disease. This was hypothesized to be due to a rise in stress hormones, depression, and anxiety, as well as the individual lacking encouragement from others to engage in healthy behaviors. In contrast, older adults who take part in social clubs and church groups have a lower risk of death. Opportunities to reside in mixed age housing and continuing to feel like a productive member of society have also been found to decrease feelings of social isolation, and thus loneliness.

Many studies have shown that populations of colonizing microbes differ between healthy individuals and others with disease or unhealthy conditions aasha herbals geriforte 100 mg without a prescription. However herbalsmokecafecom order geriforte 100 mg otc, researchers are still not able to define the composition of a healthy human microbiota. Certain commensal bacteria (such as Roseburia, Akkermansia, Bifidobacterium, and Faecalibacterium prausnitzii) appear to be associated more commonly with health, but it is a current active area of research to determine whether supplementation with these bacteria may improve health or reverse disease. Probiotics affect the intestinal ecosystem by impacting mucosal immune mechanisms, by interacting with commensal or potential pathogenic microbes, by generating metabolic end products such as short-chain fatty acids, and by communicating with host cells through chemical signaling (Fig. These mechanisms can lead to antagonism of potential pathogens, an improved intestinal environment, bolstering the intestinal barrier, down-regulation of inflammation, and up-regulation of the immune response to antigenic challenges. These phenomena are thought to mediate most beneficial effects, including a reduction in the incidence and severity of diarrhea, which is one of the most widely recognized uses of probiotics. The normal microbiota and probiotics interact with the host in metabolic activities and immune function and prevent colonization of opportunistic and pathogenic microorganisms. Symbiosis between microbiota and the host can be optimized by pharmacological or nutritional interventions in the gut microbial ecosystem using probiotics or prebiotics Probiotics Immunologic benefits Activate local macrophages to increase antigen presentation to B lymphocytes and increase secretory immunoglobulin A (IgA) production both locally and systemically Modulate cytokine profiles Induce tolerance to food antigens Nonimmunologic benefits Digest food and compete for nutrients with pathogens Alter local pH to create an unfavorable local environment for pathogens Produce bacteriocins to inhibit pathogens Scavenge superoxide radicals Stimulate epithelial mucin production Enhance intestinal barrier function Compete for adhesion with pathogens Modify pathogen-derived toxins Prebiotics Metabolic effects: production of short-chain fatty acids, absorption of ions (Ca, Fe, Mg) Enhancing host immunity (IgA production, cytokine modulation, etc. The claims that can be made about these types of product differ depending on regulatory oversight in each region. Most commonly, probiotics and prebiotics are sold as foods or supplement-type products. Typically, no mention of disease or illness is allowed, claims tend to be general, and products are targeted for the generally healthy population. Wading through the multitude of foods, supplements, and pharmaceutical products on the market is a daunting task. Both lists have been funded by unrestricted grants from commercial entities Organization Title Reference European Society Consensus Guidelines on Probiotics espcg. Since most are not made to pharmaceutical standards, the regulatory authorities may not oversee adherence to quality standards. The dose needed for probiotics varies greatly depending on the strain and product. It is not possible to state a general dose that is needed for probiotics; the dosage should be based on human studies showing a health benefit. Because probiotics are alive, they are susceptible to die-off during product storage. Spore-forming probiotic strains, although not as well studied as others, do have the advantage of superior resistance to environmental stress during shelf-life. Probiotic products on the market have been shown in some cases to fail to meet label claims regarding the numbers and types of viable microbes present in the product. Note: A specified range of permissible colony-forming units should perhaps be required in order to minimize the risks of toxicity as well as loss of effect between production and the end of shelf-life [3,4]. On the basis of the prevalence of lactobacilli in fermented food, as normal colonizers of the human body, and the low level of infection attributed to them, their pathogenic potential is deemed to be quite low by experts in the field. Most products are designed for the generally healthy population, so use in persons with compromised immune function or serious underlying disease is best restricted to the strains and indications with proven efficacy, as described in section 4. Microbiological quality standards should meet the needs of at-risk patients, as reviewed by Sanders et al. Testing or use of newly isolated probiotics in other disease indications is only acceptable after approval by an independent ethics committee. Traditional lactic acid bacteria, long associated with food fermentation, are generally considered safe for oral consumption as part of foods and supplements for the generally healthy population and at levels traditionally used. Specific recommendations for different indications are based on levels of graded evidence (Table 7) and are summarized in Tables 8 and 9. Oral administration shortens the duration of acute diarrheal illness in children by approximately 1 day. Several meta-analyses of controlled clinical trials testing other probiotic strains have been published that show consistent results suggesting that probiotics are likely to be safe and effective. However, the authors caution that additional studies are needed in order to determine the best dosage and strain. A 2013 meta-analysis [6] concluded that probiotics may be beneficial in the prevention and possibly in the treatment of radiation-induced diarrhea. There is no evidence to support the concept that a probiotic alone, without concomitant antibiotic therapy, would be effective. Evidence for one probiotic mixture suggests that it can reverse minimal hepatic encephalopathy. Evidence suggestive of enhanced immune responses has been obtained in studies aimed at preventing acute infectious disease (nosocomial diarrhea in children, influenza episodes in winter) and studies that tested antibody responses to vaccines. Probiotics can be recommended to patients with pouchitis of mild activity, or as maintenance therapy for those in remission. The literature suggests that certain probiotics may alleviate symptoms and improve the quality of life in patients with functional abdominal pain. This was confirmed in a number of controlled studies with individuals consuming yogurt with live cultures. Meta-analyses of randomized controlled trials have also shown a reduced risk of death in probiotic-treated groups, although not all probiotic preparations tested are effective. The number needed to treat to prevent one death from all causes by treatment with probiotics is 20. Although it is outside the scope of this guideline, it may be of interest to readers to note that probiotics and prebiotics have been shown to affect several clinical outcomes that are outside the normal spectrum of gastrointestinal disease. Emerging evidence suggests that gut microbiota may affect several non-gastrointestinal conditions, thereby establishing a link between these conditions and the gastrointestinal tract. Numerous studies have shown that probiotics can reduce bacterial vaginosis, prevent atopic dermatitis in infants, reduce oral pathogens and dental caries, and reduce the incidence and duration of common upper respiratory tract infections. The net benefit of probiotics during the perinatal period in preventing allergic disease has lead to a World Allergy Organization recommendation on probiotic use during pregnancy, breastfeeding, and weaning in families with a high risk of allergic disease. Probiotics and prebiotics are also being tested for the prevention of some manifestations of the metabolic syndrome, including excess weight, type 2 diabetes, and dyslipidemia. The purpose of these tables is to inform the reader about the existence of studies that support the efficacy and safety of the products listed, as some other products for sale on the market may not have been tested. There is no evidence from comparative studies to rank the products in terms of efficacy. The tables do not provide grades of recommendation, but only levels of evidence in accordance with the Oxford Centre for Evidence-Based Medicine criteria (Table 7).

The scope of Chapter 9 on Compressed gases has been widened to include additional examples together with the basic techniques of preparing gases in situ. Chapter 10 summarizes techniques for monitoring air quality and employee exposure. It has also been expanded to provide guidance on monitoring of water and land pollution. Considerations of safety in design (Chapter 12) are presented separately from systems of work requirements, i. The considerations for Marketing and transportation of hazardous chemicals are now addressed in two separate chapters (Chapters 14 and 15). Chemicals and the Environment are now also covered in two chapters (Chapters 16 and 17) to reflect the requirement that the impact of chemicals on the environment should be properly assessed, monitored and controlled. Although a substantial contribution to atmospheric pollution is made by emissions from road vehicles and other means of transport, and this is now strictly legislated for, this topic is outside the scope of this text. Chapter 18 provides useful conversion factors to help with the myriad of units used internationally. Whilst the hazards identified, and the principles and practice for the control of risks are universal, i. It is hoped that the improvements will help to achieve the objectives for which the text was originally conceived, i. The range of chemicals and chemical mixtures in common use in industry is wide: it is obviously impossible to list them all in a concise handbook, or to refer to all their proprietary names. Numerous sources not restricted to those in the Bibliography were searched for information and although not listed, to achieve conciseness, these are acknowledged. The multiplicity of data sources also means that minor variations occur due to differences in the procedures and methods for their determination; however they provide general guidance. Whilst the data quoted in this text has been carefully collated, its accuracy cannot be warranted. For this reason, and to avoid overlooking consideration of other chemical-specific hazards or location-dependent legislation, it is advisable to refer to a Chemical Safety Data Sheet before using any chemical. Act 1974, the Control of Substances Hazardous to Health Regulations 1988, the Highly Flammable Liquids and Liquefied Petroleum Gases Regulations 1972, the Control of Pollution Act 1974 and the Environmental Protection Act 1990 are supplemented by a wide variety of other measures. Legislative controls tend to change frequently and it is important to ensure that a check is made on current requirements and constraints in any specific situation involving chemicals. It also provides a useful summary for those who may need to make only passing reference to the hazardous properties and potential effects of chemicals, such as general engineering students and occupational health nurses. Different hazards may be associated with the manufacture, storage, transport, use, and disposal of chemicals. Environmental hazards, through persistent or accidental losses of chemicals, may also be related to these operations. However, biological hazards arising from the working environment or from more specialized activities. This text deals solely with occupational, industrial and environmental hazards associated only with chemicals. It includes fires and explosions since they inevitably involve chemical compounds. Chemicals are ubiquitous as air, carbohydrates, enzymes, lipids, minerals, proteins, vitamins, water, and wood. These spanned a wide range of industrial and related premises as shown in Table 1. The most common sources of ignition (see Chapter 6) that year are shown in Table 1. One estimate suggests that the chemical industry contributes to 50% of all air pollution with proportions approximating to sulphur dioxide (36%), carbon dioxide (28%), nitrogen oxides (18%), carbon monoxide (14%) and black smoke (10%). Motor spirit refining is responsible for ca 26% of emissions of volatile organic compounds to the atmosphere. In 1996 there were over 20 000 reports of water pollution incidents with 155 successful prosecutions. In the workplace it is a management responsibility to ensure practices control the dangers, and it is for employees to collaborate in implementing the agreed procedures. Management must also prevent uncontrolled environmental releases and ensure all wastes are disposed of safely and with proper regard for their environmental impact. The aims of this book are to raise awareness and to help users identify, assess and control the hazards of chemicals to permit optimum exploitation whilst minimizing the dangers. Alternatively, prolonged or intermittent exposure may result in an occupational disease or systemic poisoning. Generally acute effects are readily attributable; chronic effects, especially if they follow a long latency period or involve some type of allergic reaction to a chemical, may be less easy to assign to particular occupational exposures. The possible permutations of effects can be very wide and exposure may be to a combination of hazards. For example, personnel exposed to a fire may be subject to flames, radiant heat, spilled liquid chemicals and vapours from them, leaking gases, and the pyrolytic and combustion products generated from chemical mixtures together with oxygen deficient atmospheres. However, whether a hazardous condition develops in any particular situation also depends upon the physical properties of the chemical (or mixture of chemicals), the scale involved, the circumstances of handling or use. Hazard recognition and assessment always start from a knowledge of the individual properties of a chemical. A brief discussion of the relevance of physicochemical principles to hazard identification is given in Chapter 4. Relevant toxic and flammable properties, and summaries of appropriate precautions to cater for them during handling, use and disposal, are provided in Chapters 5 and 6, respectively. The unique problems associated with radioactive chemicals are described in Chapter 11. The foregoing relates mainly to normal laboratory or commercial quantities of chemicals. Additional considerations arise with those quantities of flammable, explosive, reactive, bulk toxic, or hypertoxic chemicals which constitute major hazards, i. The special considerations with such installations are detailed in specialist texts noted in the Bibliography. It can rarely be solved by rigidly following a checklist, although checklists, examples of which are given in the various chapters, can provide useful guidelines. And although associated hazards are not covered here, the control of chemical hazards in the workplace cannot be achieved in isolation from a consideration of electrical, mechanical, ergonomic, biological and non-ionizing radiation hazards. To ensure that an operation is under control may necessitate environmental monitoring; this is summarized in Chapter 10. General safety considerations, administration and systems of work requirements, including elementary first aid, are summarized in Chapter 13. Ammonia (anhydrous or as solution containing more than 50% by weight of ammonia) 100 t 7. Tetramethyl lead 50 t Part B Highly reactive substances and explosive substances 37. Acetylene (ethyne) when a gas subject to a pressure 620 millibars above that of the 50 t atmosphere, and not otherwise deemed to be an explosive by virtue of Order in Council No 30,(a) as amended by the Compressed Acetylene Order 1947,(b) or when contained in a homogeneous porous substance in cylinders in accordance with Order of Secretary of State No 9,(c) made under the Explosives Act 1875. Aqueous solutions containing >90 parts by weight of ammonium nitrate per 100 parts 500 t by weight of solution. Cellulose nitrate other than: (i) cellulose nitrate to which the Explosives Act 1875 applies; or 50 t (ii) solutions of cellulose nitrate where the nitrogen content of the cellulose nitrate 12. Sulphur dichloride 1 t Part C Flammable substances (unless specifically named in Parts A and B) 66. Liquefied petroleum gas, such as commercial propane and commercial butane, and 25 t any mixtures thereof, when held at a pressure >1. Liquefied petroleum gas, such as commercial propane and commercial butane, and 50 t any mixture thereof, when held under refrigeration at a pressure 1. A substance or any mixture of substances, which is flammable in air, when held 25 t above its boiling point (measured at 1 bar absolute) as a liquid or as a mixture of liquid and gas at a pressure >1. All chemical operations produce waste either as solid wastes (including pastes, sludge and drummed liquids), liquid effluents, or gaseous emissions (including gases, particulate solids, mists and fogs). Since data have been collated from a variety of sources, and tend to be presented in mixed units, and because rapid conversion of units is an advantage in many on-site situations, conversion tables are included in Chapter 18. Finally, since safety with chemicals cannot be addressed exhaustively in a handbook, selected sources of reliable current information on chemical hazards and their control are listed in Chapter 19. This effluent is feed for bacteria which consume oxygen, making it more difficult for plant and fish life to survive. It contains substances selected mainly on the basis of their toxicity, persistence and accumulation in living organisms and in sediment. Defined in Regulation 2 of the Control of Substances Hazardous to Health Regulations 1999 as: (a) any substance or preparation which if classified in accordance with the classification provided for by Regulation 5 of the Chemicals (Hazard Information and Packaging for Supply) Regulations 1994 would be in the category of danger, carcinogenic (category 1) or carcinogenic (category 2) whether or not the substance or preparation would be required to be classified under those Regulations; or (b) any substance or preparation: (i) listed in Schedule 1, or (ii) arising from a process specified in Schedule 1 which is a substance hazardous to health. Until recently they were used extensively as aerosol propellants, solvents, refrigerants and in foam making. Some plastics which contain certain chlorinated hydrocarbons release dioxins into the air, when burnt at low temperatures. Symptoms following exposure include headache, dizziness, loss of consciousness, respiratory or cardiac depression, death. The risks may include flammable substances; oxygen deficiency or enrichment; toxic gases, fume or vapour; ingress or presence of liquids; free-flowing solids; presence of excessive heat. Defined substances, including all toxic gases, all flammable gases, asbestos and most hazardous wastes, for which carriage in packages or in bulk is controlled. Discharges to public sewers are controlled by discharge consents by one of the ten Water Service Companies. Industrial activities such as smelting, rubbish burning, waste disposal and adding lead to petrol increase the amount of toxic heavy metals in the environment. The major sources of hydrocarbons in the atmosphere are vehicle emissions (unburned fuel) and gas leaks. Industries are given consents to pollute with the effect on all three media being taken into consideration. This method is commonly used for both domestic waste and more hazardous chemical waste. Landfill sites used for difficult and potentially-dangerous wastes are now engineered, managed and monitored to prevent poisons leaking out. Generally expressed as % by volume for gases and vapours, and as 3 mg/m for mists or dusts. Requirements with respect to the control of major accident hazards involving dangerous substances apply to defined establishments under the Control of Major Accident Hazards Regulations 1999. Generally comprising neat mineral oils, or water-based materials, or a mixture of the two. Fluids may also contain emulsifiers, stabilizers, biocides, corrosion inhibitors, fragrances and extreme pressure additives. Includes a wide range of hydrocarbons from light oils, kerosene and gas oils, to the heavier fuel and lubricating oils. No single widely accepted test of physiologic function can be shown to correlate with symptoms. At ground level, as a constituent of photochemical smog, it is an irritant and can cause breathing difficulties. Forms a protective screen against harmful radiation by filtering out ultra-violet rays from the sun. If the risk outweighs the sacrifice or cost, additional precautions are necessary. Becoming common practice in industry, especially with expensive commodities such as chemical solvents although many products require a commercial subsidy in order to make recycling viable. The aim was to reduce inputs of Red List substances by 50% by 1995, from 1985 levels.
