Book Description :

Persistent organic pollutants (POPs) and toxic elements, such as dioxins, flame retardants, lead and mercury, are substances of major concern for the food industry, the regulator and the public. They persist in the environment, accumulate in food chains and may adversely affect human health if ingested over certain levels or with prolonged exposure. Persistent organic pollutants and toxic metals in foods explores the scientific and regulatory challenges of ensuring that our food is safe to eat. Part one provides an overview of regulatory efforts to screen, monitor and control persistent organic pollutants and heavy metals in foods and includes case studies detailing regulatory responses to food contamination incidents. Part two moves on to highlight particular POPs, toxic metals and metalloids in foods, including dioxins and polychlorinated biphenyls (PCBs), mercury, polycyclic aromatic hydrocarbons (PAHs) and phthalates. Persistent organic pollutants and toxic metals in foods is a standard reference for those in the food industry responsible for food safety, laboratories testing for food chemical safety, regulatory authorities responsible for ensuring the safety of food, and researchers in industry and academia interested in the science supporting food chemical safety. Includes case studies which detail regulatory responses to food contamination incidents Considers the uptake and transfer of persistent organic pollutants in the food chain and the risk assessment of contaminates in food Details perticular persistent organic pollutants, toxic metals and metalloids in foods including polychlorinated biphenyls (PCBs), per- and polyfluoroalkyl substances (PFASs), mercury and arsenic among others

Book Description :

Determining the presence of different types of toxic compounds (or xenobiotics) in food requires precise analytical methodologies. Examples of these techniques include separation techniques coupled to mass spectrometry, Variations in methods used depend on the physicochemical properties of each xenobiotic being tested for. Advances in the Determination of Xenobiotics in Foods explains recent developments in the field of xenobiotic determination in food. Readers are introduced to xenobiotic testing techniques through extensive reviews. Chapters also cover details about contaminants coming from food contact materials (such as plasticizers, food additives, polymer monomers/oligomers and non-intentionally added substances), substances used for food processing and sensing (nanoparticles), and residues of pesticides (that can also be present in the final food product). The book also includes information about specific xenobiotics that, due to their global distribution in the environment, are also likely to enter the food chain. Some of them are regulated (persistent organic pollutants and heavy metals) but there are many other types of contaminants (halogenated flame-retardants, perfluorinated compounds and micro- and nanoplastics) that must also be controlled. In addition, some xenobiotics could be present in the final food consumed because of food treatments (acrylamide, furan, heterocyclic aromatic amines, and glycidol esters). Finally, the concluding chapters of the book are devoted to the presence of natural contaminants such as mycotoxins and biogenic amines. The combination of extensive information of analytical techniques for xenobiotics along with a categorical treatment of food contaminants makes this volume a handy reference for food science and technology students and technicians involved in food safety and processing management roles. SERIES INTRODUCTION: This book series presents reviews, and reference monographs on all aspects of food science and technology. The series is essential reading for food chemists and technician in both professional and academic settings.

Book Description :

There is widespread public concern about hazardous chemicals that are contained in air, soil, water and food. Policy has therefore adopted a series of laws and regulations concerning emissions into and concentration levels in different media including food. As policy makers do not only have to consider the protection of the environment but also need to ensure a well-functioning economy at the same time, these limit or target values need to be set in a balanced way. The main problem, however, is to compare the costs for achieving these targets with the benefits to society by having a smaller exposure to hazardous substances (cost-benefit analysis). This book sets out to improve the reliability of cost-benefit analyses particularly of hazardous substances present in air, water, soil and food. It suggests that the human health risk assessment of chemicals is performed in a bottom-up analysis, i.e., following a spatially resolved multimedia modelling approach. In order to support cost-benefit analyses, the approach is accompanied by monetary valuation of human health impacts, yielding so-called external costs. Results for selected priority metals show that these external costs are small compared to those by the classical air pollutants and involve rather long time horizons touching on the aspect of intergenerational equity within sustainable development. When including further hazardous substances, the total external costs attributable to contaminants are expected to be more substantial.

Book Description :

De Hollander et. al. (1999) & Melse and De Hollander ( 2001) showed that total burden of disease, with estimated environment-related share expenditure, mid-1990 year. The average income group has 15 daily/1000 capita, the middle income group has 20 daily/1000 capita, the high income group has 10 daily/1000 capita. As regards both total burden of disease and the health conditions related to environmental; degradation. The result indicates the environment -related share of the burden of disease is greatly dependent on income, with higher-environmental shares generally occurring in lower-income countries. On the one hand, it seems the large environmental share of health problems is primarily, due to factors related to poverty, such as limited to access to proper food, housing, health care and drinking water. Environmental determinants of human health in developing or developed countries are related. On the other hand, those to the exposure to air pollutants ( particularly in urban areas and chemicals in the environment than to poor living conditions. Also sources of human exposure to chemicals are many and varied. Chemicals can reach the environments, for example, through emissions from industries, anti-fouling paints on marine vessels, pesticides in agriculture, waste incineration and leakage from waste disposal sites. When emissions of chemicals from industries and other point sources of pollution have lead to poor quality of life, source of chemical exposure. Intensive agricultural production uses chemicals in pesticides and fertilizer and in feed additives and medication for livestock. Residues remain in fruit, grains, vegetables, meats and daily products, all of which can reach the consumer. Other sources of chemicals in food include bio-accumulative chemicals in the environment, such as heavy metals and persistent organic pollutants, which can be found in fish, meat and dairy products. So, environment pollution can influence human need to eat bad or unhealthy food to cause we have poor quality of life to live, such as the high income group or middle income group or low income group of families in our societies fairly. Other human health risks that have recently received considerable attention include unsafe livestock feeding practices through which toxins reach the food chain unintentionally. Dioxins that have accidentally contaminated poultry feeds that contain diseased animal remains can cause the so-called " mad cow disease" in livestock which has been linked to a new form of disease. The effects on health from exposure to chemicals and air pollutants vary from allergies to cancer. Although, the link between exposure and disease is often not clear, Even at low exposure levels, urban are pollutants can cause, asthma, allergies, respiratory diseases and cardiovascular disease if the exposure is continuous or long term. Heavy metals have been shown to cause neurological disorders and various cancers. In addition to , physical diseases, environmental contamination can also cause psychological problems. Noise, one of the determinants of the quality of urban life can have an impact on human health, decreasing the quality of life and potentially contributing to depression.

Agreement on what measures quality of life and how it can be measured by the role of environment, not just in Ireland, but everywhere. The conventional approach is used for policy has been to use measure of gross domestic product( GDP) or regional valued added. However, it is acknowledged that such conventional economic measures have only a partial relationship with societal wellbeing. To the extent that economic measures are related to public products and consumption, there are also pressing issues in relation to public products and the sustainability of economic growth. However, the role of environmental factor can influence resource use and human's behavioral consumption.

The international advanced research workshop funded by NATO and entitled “impact of pollutions on animal and animal products” was organized at Almaty (Kazakhstan) on 27–30 September 2007. Thirty-one scientists from 12 countries (Kazakhstan, Kirgizstan, Azerbaijan, Ukraine, Russia, France, Great Britain, Italy, Belgium, Romania and Morocco) presented conferences at this meeting to share their experience and results. The programme included three main aspects: (i) generality on the pollution situation in Central Asia and former Soviet Union republics, (ii) the pollution area and pollution origin in Central Asia and Western countries in relation with animal health, and (iii) the relationships between soil contamination, plant contamination and animal products status. The present workshop contributed highly to the exchange between scientists giving the opportunity for researchers from Central Asia to access to new scientific approaches and methodologies, and for European scientists to assess the extent of the environmental problems in this part of the world. No doubt that these exchanges were the main success of the workshop marked by very stimulating discussions. Such meeting was also the opportunity to put on the first stone of a scientific network focused on the subject of the workshop. The importance of pollution in Central Asia in general and in Kazakhstan in p- ticular is a well-known feature and several references are available on the source and localization of pollution problems in those countries. The references are also abundant on the impact of the environmental failures on human health.

Book Description :

Healthy environment is important for any kind of biota on earth. It provides the basic elements of life such as clean water, fresh air, fertile soil and supports ecosystem of the food chain. Pollution drastically alters quality of the environment by changing the physico-chemical and biological aspects of these components. Accordingly, toxic metals, combustible and putrescible substances, hazardous wastes, explosives and petroleum products are all examples of inorganic and organic compounds that cause contaminations. Specifically, pollution of toxic and heavy metal in the environment is a growing problem worldwide, currently at an alarming rate. Toxic metals threaten the aquatic ecosystems, agriculture and ultimately human health. Traditional treatment techniques offer certain advantages such as rapid processing, ease of operation and control and flexibility. But, they could not maintain the quality of the environment due to the high operational costs of chemicals used, high energy consumption and handling costs for sludge disposal and overburden of chemical substances which irreversibly affect and destroy biodiversity, which ultimately render the soil useless as a medium for plant growth. Therefore, bioremediation and biotechnology, carried out by living assets to clean up, stabilize and restore contaminated ecosystems, have emerged as promising, environmental friendly and affordable approaches. Furthermore, the use of microbes, algae, transgenic plants and weeds adapted to stressful environments could be employed to enhance accumulation efficiency. Hence, sustainable and inexpensive processes are fast emerging as a viable alternative to conventional remediation methods, and will be most suitable for developing countries. In the current volume, we discuss pollution remediation challenges and how living organisms and the latest biotechnological techniques could be helpful in remediating the pollution in ecofriendly and sustainable ways.

This book provides examples of pollutants, such as accidental oil spills and non-degradable plastic debris, which affect marine organisms of all taxa. Terrestrial runoff washes large amounts of dissolved organic materials from agriculture and industry, toxic heavy metals, pharmaceuticals, and persistent organic pollutants which end up into rivers, coastal habitats, and open waters. While this book is not intended to encyclopaedically list all kinds of pollution, it rather exemplifies the problems by concentrating on a number of serious and prominent recent developments. The chapters in this book also discuss measures to decrease and remove aquatic pollution to mitigate the stress on aquatic organisms. Aquatic ecosystems provide a wide range of ecological and economical services. In addition to providing a large share of the staple diet for a fast growing human population, oceans absorb most of the anthropogenically emitted carbon dioxide and mitigate climate change. As well as rising temperatures and ocean acidification, pollution poses increasing problems for aquatic ecosystems and organisms reducing its functioning and services which are exposed to a plethora of stress factors.

Book Description :

Water is an indispensable element for human life. However, clean water supply is a worldwide issue nowadays. This is because of pollution due to anthropogenic activities that are related to the increase of human population. The man-induced inputs as important sources of pollution contribute to the contamination of water quality in rivers and reservoirs. These pollutants include domestic organic wastes, industrial wastes, heavy metals, oil and grease, polycyclic aromatic hydrocarbons, endocrine disrupting chemicals, persistent organic pollutants, etc., which can deteriorate the natural chemistry of water. Monitoring the pollutant levels in water bodies is an important issue, since their elevated levels could be hazardous to biota that live in the water body and the sedimentary compartment of the aquatic ecosystems, partly or mostly being the natural resources in the food chain up to human being. Therefore, water pollution will always remain a never-ending story, today's society will be faced with. To conclude, the aim of this workshop was to update the knowledge on water related issues and to discuss practical solutions to reduce (if even not to stop) water pollution while integrating experts from technological, environmental and social-economic fields.

Book Description :

This book covers all aspects of bioavailability, as related to environmental contaminants. After a discussion of the definition of bioavailability and its context, focus is placed on the role of risk assessment and bioavailability. Methods of analysis are then discussed including a range of atomic spectroscopic and electrochemical techniques for metal analysis and chromatographic approaches for persistent organic pollutants (POPs). The occurrence, properties and eco-toxicity of POPs and metals in the soil/sediment environment are discussed. Particular emphasis is placed on the uptake of POPs and metals by plants (phytoextraction). Examples of POPs and metals in the environment are reviewed. Methods to assess the bioavailability of POPs and metals in the environment are discussed. The particular approaches considered are: non-exhaustive extraction techniques single extraction techniques sequential extraction techniques use of cyclodextrin and surfactants in-vitro gastrointestinal methods including physiological-based extraction test the use of bioasssays including earthworms. Finally, selected case studies highlight the importance of determining the bioavailability of POPs and metals.
