Today, we are surrounded by a multitude of different chemicals that are essential components of our everyday life. As a consequence, there are various hazardous substances like dioxins, phthalates and flame-retardants circulating in the environment. These have an impact on ecosystems, wildlife and possibly human health. In recent years, the phenomenon called endocrine disruption has raised considerable concern. This book discusses the scientific basis of this issue using epidemiological and experimental in vitro and in vivo data about chemicals targeting the hormonal systems. It also provides an up-to-date review of international initiatives (including high-throughput screening, use of model organisms and in silico applications) aiming to screen, detect and functionally test these chemicals. The authors are highly experienced academics and acknowledged experts with both multidisciplinary and international expertise. The book provides an up-to-date, in-depth review of the current field of food safety research describing many of the "hot topics" currently debated. Recent media attention concerning, for example, dioxins in meat and bisphenol A in baby bottles has created a growing interest in food safety-related issues from both consumers and authorities. In addition, European legislation REACH, which requires industry to extensively test chemicals, has led to new initiatives within this area. This book presents a comprehensive overview of the recent international initiatives formed to meet the challenges of environmental pollutants in our food.

The rise in the incidence of health problems such as reproductive disorders and testicular and breast cancer has been linked by some to endocrine disrupting chemicals in the environment. The role of food in transmitting these chemicals is uncertain and a topic of considerable research. This important book addresses key topics in this area. The first part of the book reviews the impacts of endocrine disrupting chemicals on health and behaviour, with chapters on the effect of dietary endocrine disruptors in such areas as the developing foetus, cancer and bone health. Parts two and three focus on the origin and analysis of endocrine disruptors in food products and risk assessment. Topics addressed include surveillance, analysis techniques such as biosensors, exposure assessment and the relevance of genetics, epigenetics and genomic technologies to the study of endocrine disrupting chemicals. Concluding chapters discuss examples of selected endocrine disrupting chemicals associated with food, such as dioxins, polychlorinated biphenyls and brominated flame retardants, bisphenol A and phytoestrogens and phytosterols. With its distinguished editor and international team of contributors, Endocrine-disrupting chemicals in food is an essential reference for all those concerned with ensuring the safety of food. Reviews the impacts of endocrine disrupting chemicals on health and behaviour including cancer and reproductive disorders Addresses the origin and analysis of endocrine disruptors with chapters on surveillance and analysis techniques Examines the relevance of genetics, epigenetics and genomic technologies to endocrine disrupting chemicals

What causes cancer, type-2 diabetes and other debilitating conditions? Often it's the toxic chemicals that surround us and infiltrate our bodies. Healthy Living in a Contaminated World shines a light on these toxic chemicals and leads the reader toward a healthier life. It describes the health damages caused by specific chemicals, and recommends actions that people can take to avoid exposure to them.The second edition contains new information on three key topics: children's health, hormone disrupting chemicals, and breast cancer. These major heath topics are illuminated by the EPA's report on the effects of environmental chemicals on children; the World Health Organization's report on the effects of hormone disrupting chemicals on reproduction, neurological development, and metabolic and immune disorders; and insights into breast cancer by the Silent Spring Institute, the Breast Cancer Fund, and the book, “The Ecology of Breast Cancer.”

This book contains contributions based on the proceedings of two symposia on food contamination held in London in April 1989 and May 1990, both of which were organised jointly by the Environment, Food Chemistry and Toxicology Groups of the Royal Society of Chemistry. The aim of these meetings was to assess the extraneous chemical contamination of food from two sources: firstly, food-chain contaminants - the presence of plant toxicants of fungal metabolites in food, or the contamination of food from environmental sources (airborne, aquatic and terrestrial); and secondly, food-production contaminants - contaminants of man-made origin brought about by a desire to facilitate food production and distribution. The contributors concentrate on the contamination of food by chemicals arising from environmental and food-production sources. Chapter 1 is concerned with food-chain contaminants present in food as natural components of the diet. This is followed by discussion of the chlorinated dioxins and furans, and polycyclic aromatic hydrocarbons. Following an introduction to the control and surveillance of food-production contaminants, four areas of activity are described: migration from food contact materials with particular reference to plastics, the analysis and regulatory control of veterinary products, the analysis of pesticides in drinking water and finally the problem of food taints.

In recent years, it has become evident that many chemicals present in the environment can mimic, antagonize or alter the physiological actions of endogenous hormones. These compounds have been termed endocrine disrupters (EDs) and defined as exogenous substances that cause adverse health effects in an intact organism or in its progeny, consequent to changes in endocrine function [1]. EDs, even when present in minute amounts (part per trillion), could interfere with the synthesis, secretion, transport, metabolism, binding, action, or elimination of natural hormones responsible for homeostasis maintenance, reproduction, and developmental processes [2]. Currently more than 100 chemicals have been identified as EDs. Within this heterogeneous group of molecules we find: (a) synthetic chemicals used in industry, agriculture, and consumer products; (b) synthetic chemicals used as pharmaceutical drugs; and (c) natural chemicals found in human and animal food. About half of these compounds are substituted with halogen groups, mostly chlorine and bromine, and include dioxins, polychlorinated biphenyls, organochlorine pesticides, methoxychlor, dieldrin, and hexachlorocyclohexane. EDs have long environmental half-life resulting in a continue increase of their global concentration in the environment and can be detected and may concentrate at great distances from where they are produced, used or released. EDs have very low water solubility and extremely high lipid solubility, leading to their bioaccumulation in adipose tissue. Exposure to EDs can occur from a number of different sources: humans and animals can be exposed involuntarily by drinking contaminated polluted water, breathing contaminated air, ingesting food, contacting contaminated soil or even in the workplace. Although endocrine disruption has only received high-profile attention for just over a decade [2], the phenomenon does have a longer historical background. In the early 1900s, pig farmers in the USA complained of fertility problems in swine herds fed on moldy grain [3], and concern was stimulated in the 1940s by reports of infertility in sheep grazing on certain clovers in Western Australia [4]. Over the following two decades, estrogenic actions were evidenced in birds [5] and in mammals [6] owing to the dissemination of the agrochemical orto-dichlorodiphenyltrichloroethane (DDT), at the same time masculinization of bivalves and gastropods[7], with concomitant declines in population, was found in the 1970s with the introduction of tributyltin into antifouling paints for the boats, while feminization of fishes was observed in UK rivers in the presence of estrogenic components in sewage effluent [8]. Also the occurrence of genital abnormalities in both male and female alligators in Lake Apopka (FL, USA) were observed as effect of a spill of the pesticide difocol in 1980. After these first observations the scientific community increased the awareness of the consequences of exposure to chemicals which can interfere with reproductive functions [9]. Endocrine disruption in wildlife is now acknowledged to be a widespread problem, much resulting from environmental pollution, and, in the case of aquatic forms of wildlife, from the continuous exposure to these chemicals in the water. Extrapolation of the results of these researches on wildlife resulted in concern that the same compounds could interfere with hormone action in humans. Handling hazardous substances and the risk of exposure to chemicals are a painful part of modern life, as technology and science progress. Moreover, exposure to chemicals present in foods, at home, and at work is an important risk factor for human health, especially since our scientific knowledge is still not sufficient to ensure proper prevention. Nowadays there is justifiable concern that endocrine disruption could be the underlying cause of increasing female and male reproductive problems, thus endocrine disruption is one of the topics receiving much attention throughout all sectors of the society, and the debate between pharmaceutical companies and public health organisms is increasing. Both parts will call for urgent need of more research. The scientific challenge for the future is to identify the relevant real-life sources of exposure of the human population to endocrine-disrupting compounds and to find the appropriate remediation actions. This can be done: (a) by assessing the impact on human health of long-term, low-dose exposure to such chemicals; (b) by understanding the synergistic effects of the copious number of chemicals to which humans and animals are exposed; (c) by defining the variety of underlying mechanisms at molecular, cellular and physiological level, (d) by exploiting new technologies addressed to the remediation of the environment polluted by the presence of EDs, and (e) by designing and developing new sensors or biosensors capable of determining their concentration in traces. The review presented in this book has been written under the sponsorship of the Interuniversitary Consortium National Institute of Biostructures and Biosystems (INBB) , constituted by 26 Public Italian Universities. INBB is stimulating the research on endocrine disruptors, by encouraging and coordinating joint research projects between its members and those of other Italian public scientific institutions. This book represents one of the results of the meeting The biological and clinical research on endocrine disruptors: current status and perspectives , held in Rome during 2005 from October 27 to 28 and organized by INBB and ISPESL (Istituto Superiore Prevenzione e Sicurezza del Lavoro). The first three chapters of this book review the EDs effects on natural population living in aquatic ecosystems where EDs, due to their lipophilicity, tend to concentrate in sediments and in food webs. The edible mussel Mytilus (Chapter 1), a marine bivalve that can accumulate large amounts of organic contaminants, represents a species of economical, ecological and public health-related interest. Amphibians (Chapter 2) are favourite models for studying various aspects of reproduction, development of the central nervous system and metamorphosis. Moreover, there is great concern about the EDs and the dramatic decline of wild amphibian populations. In Chapter 3 different species of fishes are considered as experimental models to analyze, by both genomic and proteomic approaches, the expression of key molecules involved in reproduction and in detoxification processes. The following two chapters focus on the EDs effects on thyroid functions and on the development of central mechanisms controlling reproduction. Wildlife observations in polluted areas clearly demonstrate a significant incidence of thyroid imbalance in several species. Several EDs are now known or suspected to be thyroid disruptors altering thyroid economy at multiple levels. These compounds may interfere with thyroid homeostasis through many mechanisms of action, at receptor level, in binding to transport proteins, in cellular uptake mechanisms or in modifying the metabolism of thyroid hormones. Chapter 4 offers a focus on endocrine disrupting activity of chemical compounds on thyroid function. The dimorphic control of reproductive functions depends on the ability of the central nervous system, particularly the hypothalamus, to respond properly to circulating reproductive hormones. This ability is acquired during a perinatal critical period, when the presence of different levels of sex steroid hormones in male and female fetuses/neonates induces a sex-specific morpho-functional development of the neuronal networks controlling reproduction. The perinatal stage is thus particularly sensitive to endogenous or exogenous substances that interfere with the activities of sex steroid hormones. Chapter 5 summarizes the current knowledge on the neuro-endocrine disrupting potential of the perinatal exposure to the major classes of EDs focusing the attention on animal studies aimed to identify the EDs action mechanisms and the resulting impairment of the reproductive behavior. Flavonoids are defined as naturally occurring molecules of plant origin, capable of acting as hormone mimetics or antagonists, but also as endocrine disruptors. Many of them have been marketed as dietary supplements or nutraceuticals with health claims, thus leading to significant increase in flavonoid consumption levels in the Western population. Even though several reports suggest for these compounds health-promoting effects in preventing age-related diseases such as atherosclerosis, hormone-dependent cancers, and osteoporosis, the mechanistic aspects of their activity have not been fully clarified and a wide consensus of the pros and cons of their use in humans has not been reached by the scientific community. Chapter 6 presents an overview of the state of the art of the knowledge on the molecular mechanisms underlying flavonoids estrogen-like activity. Feed additives represent a major issue for the safety of foods of animal origin, as they constitute the bulk of chemicals used in animal production. Feeds can also be a major vehicle for human dietary intake of persistent EDs (Chapter 7). Farm animals ingest these substances with food and drinking water and it is likely that the range of ingestion will increase in the future as growing amounts of sewage sludges are recycled onto agricultural land with an overall increase of environmental contamination exerting adverse effects on human health. Research on how the exposure to EDs affects human health in the work environment (Chapter 8) attracts increasing attention among international scientists. Certain workplaces pose particular problems as regards the potential risk connected to processes involving the use, manufacture and handling of these chemicals, and the type of job that puts workers at greatest risk of contact with them. Some EDCs represent occupational risk factors credibly capable of inducing hormone-dependent tumors. Occupational exposure to EDs is a highly complicated question: risk factors in the workplace must be identified; how they penetrate the body has to be established; confounding factors in everyday environments are numerous, and it is hard to make a definite diagnosis of their effects on human health. Owing to the harmful health effects of EDs, the attention of many scientists has been attracted towards the remediation of environment polluted by their presence and the design and development of sensors or biosensors capable of determining their concentration in traces. In Chapter 9 the experimental results concerning the enzymatic remediation of waters polluted by Bisphenol A (BPA), taken as a model of endocrine disruptors, is discussed in view of the potential application of the technology of non-isothermal bioreactors to the treatment of polluted waters. Also the functioning of a tyrosinase-based sensor able to measure the BPA concentration in traces is presented in the same chapter. These reviews emphasize that many environmental chemicals possess endocrine-disrupting properties, and that exposure to such chemicals can have adverse effects on health and reproduction even at very low concentrations. Great care should be used when attempting to apply these data to other species or real life situations. Indeed only a paucity of information is available on the metabolism and tissue distribution of these chemicals which may vary according to species physiology as well as to levels and duration of exposure. Furthermore, the possible interactions between single contaminants of the complex mixtures present in the environment may induce completely unpredictable effects, due to synergies or reciprocal inhibition effects, suggesting great caution in drawing conclusions. It is hoped that these reviews will serve to stimulate further research on EDs and human health.

The best way to avoid food-borne illnesses is to prevent contaminants from getting into food. Public health is a constant concern for world health authorities since not only food-borne illnesses but also diverse human illnesses associated to fat, salt and sugar intake, are increasingly prevalent. These diseases are caused by micro-organisms, harmful chemicals or excess of some food components in foods which people preferably drink or eat. On the other hand, chemicals can produce both acute and chronic diseases depending on the level of contaminants present in the food. When the level of contaminants is high, the result may be an acute disease with dramatic consequences, but when the level of contaminants is low; they may accumulate in a live organism and produce a long term disease. Usually, chemical contaminants are found in the environment, both naturally and produced by human activity. In this sense, prevention is therefore the principal focus of all safety quality systems in the food industry and rules to change this system in order to assure people safe food products of the required quality by the consumer are discussed. Since food contamination can happen at any place during processing, it is necessary to evaluate all the hazards that can occur all along the food production chain, identifying inputs, and analysing and controlling all critical points to keep hazards at acceptable levels.

Insight into the role of hormones, particularly estrogen and testosterone, in health and disease etiology - including interactions with other hormone pathways - has dramatically changed. Estrogen and androgen receptors, with their polymorphisms, are key molecules in all tissues and are involved in a number of homeostatic mechanisms but also pathological processes including carcinogenesis and the development of metabolic and neurological disorders such as diabetes and Alzheimer's disease. Endocrine disrupting chemicals (EDCs) can interfere with the endocrine (hormone) systems at certain dosages and play a key role in the pathology of disease. Most known EDCs are manmade and are therefore an increasing concern given the number commonly found in household products and the environment. This book will cover the mechanisms of EDC pathology across the spectrum of disease, as well as risk assessment and government and legal regulation to provide a holistic view of the current issues and cutting-edge research in the topic. With contributions from global leaders in the field, this book will be an ideal reference for toxicologists, endocrinologists and researchers interested in developmental biology, regulatory toxicology and the interface between environment and human health.

A leading voice in public health policy and top environmental medicine scientist reveals the alarming truth about how hormone-disrupting chemicals are affecting our daily lives--and what we can do to protect ourselves and fight back. Lurking in our homes, hiding in our offices, and polluting the air we breathe is something sinister. Something we've turned a blind eye to for far too long. Dr. Leonardo Trasande, a pediatrician, professor, and world-renowned researcher, tells the story of how our everyday surroundings are making us sicker, fatter, and poorer. Dr. Trasande exposes the chemicals that disrupt our hormonal systems and damage our health in irreparable ways. He shows us where these chemicals hide--in our homes, our schools, at work, in our food, and countless other places we can't control--as well as the workings of policy that protects the continued use of these chemicals in our lives. Drawing on extensive research and expertise, he outlines dramatic studies and emerging evidence about the rapid increases in neurodevelopmental, metabolic, reproductive, and immunological diseases directly related to the hundreds of thousands of chemicals that we are exposed to every day. Unfortunately, nowhere is safe. But, thanks to Dr. Trasande's work on the topic, and his commitment to effecting change, this book can help. Through a blend of narrative, scientific detective work, and concrete information about the connections between chemicals and disease, he shows us what we can do to protect ourselves and our families in the short-term, and how we can help bring the change we deserve.
