A number of the classes of chemicals suspected of causing endocrine disruption fall within the purview of the U.S. Environmental Protection Agencys ( EPA ) mandates to protect both public health and the environment. Although there is a wealth of information regarding endocrine disruptors, many critical scientific uncertainties still remain. In 1996, EPAs Office of Research and Development ( ORD ) identified endocrine disruption as one of its top six research priorities and developed a risk-based research approach to address some of these uncertainties. ORDs research program is based on a peer-reviewed Research Plan published in 1998 ( www.epa.gov/ORD/WebPubs/final

This site provides you information about endocrine disruptors and EPA's approach and progress for screening and testing chemicals for potential endocrine disruption. You will also find information about EDSP's program activities and upcoming meetings. In recent years, some scientists have proposed that certain chemicals might be disrupting the endocrine system of humans and wildlife. A variety of chemicals have been found to disrupt the endocrine systems of animals in laboratory studies, and compelling evidence shows that endocrine systems of certain fish and wildlife have been affected by chemical contaminants, resulting in developmental and reproductive problems. Based on this and other evidence, Congress passed the Food Quality Protection Act in 1996, requiring that EPA initiate EDSP to screen pesticide chemicals and environmental contaminants for their potential to affect the endocrine systems of humans and wildlife.

Extractions: The endocrine system is a complex network of glands and hormones that regulates many of the body's functions, including growth, development and maturation, as well as the way various organs operate. The endocrine glands including the pituitary, thyroid, adrenal, thymus, pancreas, ovaries, and testes release carefully-measured amounts of hormones into the bloodstream that act as natural chemical messengers, traveling to different parts of the body in order to control and adjust many life functions. An endocrine disruptor is a synthetic chemical that when absorbed into the body either mimics or blocks hormones and disrupts the body's normal functions. This disruption can happen through altering normal hormone levels, halting or stimulating the production of hormones, or changing the way hormones travel through the body, thus affecting the functions that these hormones control. Chemicals that are known human endocrine disruptors include diethylstilbesterol (the drug DES), dioxin, PCBs, DDT, and some other pesticides. Many chemicals, particularly pesticides and plasticizers, are suspected endocrine disruptors based on limited animal studies.

Extractions: Modern society has developed an extensive array of synthetic chemicals over the last several decades - chemicals to control disease, increase food production, and to provide convenience in our daily lives. Ironically, many of these well-intentioned chemicals are now wreaking havoc around the world, threatening the health of wildlife and people. As WWF tracks the growing body of scientific research on chemical contamination and the effects of exposure, a sobering picture emerges. Wherever scientists look - the tropics, marine systems, industrial regions, the Arctic - they find the effects of toxic chemicals. Wildlife, people and entire ecosystems are threatened by chemicals that can alter sexual and neurological development, impair reproduction, and undermine immune systems. Today there is unequivocal evidence that a number of widely distributed synthetic chemicals have already caused serious damage to the health of wildlife and people and pose an ongoing danger. Wildlife as diverse as polar bears, whales, frogs, eagles, and fish are contaminated with pesticides and industrial chemicals. Many scientists have concluded that synthetic chemicals have damaged wildlife populations by causing decreased fertility, thyroid dysfunction, behavioral abnormalities, decreased hatching success, and feminization and demasculinization in males.
Questions About Endocrine Disruptors Questions about endocrine disruptors. Here are some of the most frequently asked questions about the endocrine system and endocrine disruptors http://ace.orst.edu/info/extoxnet/faqs/pesticide/endocrine.htm
Extractions: Questions about Endocrine Disruptors Here are some of the most frequently asked questions about the endocrine system and endocrine disruptors: The endocrine system is composed of ductless glands that secret hormones into the blood stream to act at distant sites. Together with the nervous system, the endocrine system is responsible for the integration of many different processes which allow complicated organisms to function as a unit (maintain homeostasis). What does the endocrine system look like? Hormones can be proteins, polypeptides, amino acids, or steroids. The most well known hormones are the sex steroids estrogen, produced in the ovaries, and testosterone, produced in the testes. Estrogen and testosterone are also produced in the adrenal glands of both sexes. Other hormones include thyroxin, produced in the thyroid, and insulin, produced in the pancreas. The pituitary and hypothalamus in the brain release a variety of hormones that affect other organs, including the sex glands. How do hormones work?

Extractions: EDKB Home ... Publications Endocrine disrupting compounds (EDC's) are chemicals that either mimic endogenous hormones, interfere with pharmacokinetics or act by other mechanisms. A comprehensive definition of endocrine disruptors, given in [ Kavlock, 1996 #40 ] follows: "An exogenous agent that interferes with the production, release, transport, metabolism, binding, action or elimination of natural hormones in the body responsible for the maintenance of homeostasis and the regulation of developmental processes." This definition includes the general types of mechanisms for endocrine disruptors. Such adverse effects as compromised reproductive fitness, functional or morphological birth defects, cancer and altered immune functions, among others, have been reported in the scientific press for wildlife, in vitro, and in vivo studies. These findings have received considerable attention in the popular press, led to government regulatory actions and expanded research in Europe, Asia and the U.S. Many suspected endocrine disruptors (ED's) are high-volume, economically important chemicals, a factor that magnifies the need for resolution of the scientific issues [ Kavlock, 1996 #40

Extractions: Search for: Printer-friendly version Fast Facts Last update: February 24, 2003 In recent years, scientists have found that in addition to any known toxic effects, many industrial chemicals, pesticides and heavy metals can interfere with the endocrine systems of humans and wildlife by mimicking natural hormones. Endocrine disruptors can cause health problems at doses far below the threshold for acute toxicity. Numerous animal studies have found that extremely low doses of endocrine disruptors may contribute to abnormal sexual development, reproductive disorders, behavioral disorders and diseases affecting gland tissue, such as breast and prostate cancer. When endocrine disruptors enter the body, they disrupt the body's natural processes by sending false messages, blocking real messages, preventing synthesis of the body's own hormones, and accelerating the breakdown and excretion of hormones. Endocrine disruptors are now ubiquitous in the environment; they have even been found in the breast milk of Inuit women in the remote Arctic where known endocrine disrupting chemicals are neither used nor produced. A range of scientific studies have linked endocrine disruptors to: Reproductive disorders Immune system dysfunction Certain types of cancer Congenital birth defects of the penis (hypospadias) Neurological effects in humans and wildlife Attention deficit and poor short-term memory Low IQ Falling sperm counts Early onset of puberty in young girls
