Our commitment Endocrine disruptors Endocrine disruptors Endocrine disrupting chemicals are a group of compounds that can cause adverse effects on the hormone systems of animals. Some substances, such as natural and synthetic oestrogens have always been known to have such effects. However, in the 1990s, new, more sensitive test methods indicated that a much wider range of substances might be capable of acting as oestrogen mimics and having similar effects. This discovery was then immediately linked with a very wide range of problems being seen in humans and wildlife that appeared to be due to impacts on hormonal systems. The most often reported impact was the apparent decline in human male sperm count, with the associated concerns over human fertility. In the environment, a number of impacts were similarly attributed to endocrine disrupting chemicals, the most significant of which, was the feminisation of fish in lowland rivers of the United Kingdom. However, this link was only theoretical, and a very large amount of research work is currently being carried out, primarily to answer the following questions. What substances might have endocrine disrupting properties and how might they be identified?

The importance of these issues and the credibility of these scientists makes reading this report a priority for all of us. Statement from the Work Session on Environmental Endocrine-Disrupting Chemicals Neural, Endocrine and Behavioral Effects A multidisciplinary group of international experts gathered for a work session on "Environmental Endocrine-Disrupting Chemicals: Neural, Endocrine and Behavioral Effects" under the auspices of the International School of Ethology at the Ettore Majorana Centre for Scientific Culture in Erice, Sicily, November 5-10, 1995. The need for this work session grew out of evidence accumulated since the first consensus statement on endocrine disrupting chemicals was released in October, 1991. The first statement was framed as a product of a work session on "Chemically-Induced Alterations in Sexual and Functional Development: The Wildlife/Human Connection." Research since 1991 has reinforced concerns over the scope of the problems posed to human health and ecological systems by endocrine-disrupting chemicals. New evidence is especially worrisome because it underscores the exquisite sensitivity of the developing nervous system to chemical perturbations that result in functional abnormalities. Moreover, the consequences of these perturbations depend upon the stage of development during which exposure occurs and are expressed in different ways at different times in life, from birth through to advanced age.

43. An Overview Of The Endocrine Disruptor Screening Program
    Some scientists have suggested that such harmful chemicals, known as endocrine disruptors, are prevalent among the chemicals with which we come into contact  
    http://www.hsus.org/ace/11412
    
    Extractions: The Environmental Protection Agency is developing a program to assess whether chemicals can cause harmful effects on people by disrupting their endocrine system, the hormone-secreting glands that regulate important bodily functions such as blood-sugar levels. Some scientists have suggested that such harmful chemicals, known as "endocrine disruptors," are prevalent among the chemicals with which we come into contact, and that they may cause problems such as low sperm count in mature males and premature sexual development in young girls. Congress took up this issue and enacted legislation that called upon the EPA to establish an endocrine disruptor (ED) screening program and to adhere to an ambitious timetable. The EPA established the now defunct Endocrine Disruptor Screening and Testing Advisory Committee (EDSTAC) and charged it with coming up with an appropriate battery of tests for assessing pesticides, industrial chemicals, and environmental contaminants. Unfortunately, EDSTAC's proposed battery relies heavily on animal tests. Thousands of chemicals would be run through this battery, unproven in its relevance as an ED screen, making the Endocrine Disruptor Screening Program (EDSP) one of the largest animal testing exercises in history. Animal protectionists and sympathetic scientists have criticized EDSTAC's proposed battery on several grounds: It is based on an unproven hypothesis about widespread harm to people from endocrine disruptors; it has never been validated for the purpose of ED screening; and it ignores alternative approaches. Moreover, key meetings of the Endocrine Disruptor Standardization and Validation Task Force, formed to develop, standardize, and validate the EDSTAC-recommended screens and tests, took place behind closed doors and without adequate public input. A new panel has been created, including people from the animal protection community who have been involved in this issue.

    Extractions: Pesticides, Endocrine Disruptors, and Other Toxic Substances CDC is collaborating with the Texas Department of Health and the United States Environmental Protection Agency (USEPA) on a pilot surveillance project to track acute, nonoccupational, pesticide-related health conditions. The purpose of this surveillance program is to evaluate the public health impact of nonoccupational pesticide exposures in Texas. It involves active case finding and follow-up activities, outbreak investigations, and intervention/prevention activities. A final component will evaluate the program for completeness and representativeness of the case-finding effort. CDC is assisting the New Mexico Department of Health to evaluate statewide 1998 poison control center reports of nonoccupational pesticide poisoning. CDC will then use a descriptive analysis of the data to identify intervention/ prevention activities that may help reduce nonoccupational pesticide poisoning in New Mexico. CDC is collaborating with USEPA, other government agencies, and industry representatives in developing specific interventions to reduce children’s exposures to rodenticide products. Interventions will include labeling changes and educational activities. Although adverse health effects are rare, thousands of children are exposed yearly, resulting in many unnecessary visits to emergency rooms and doctors' offices.

    Extractions: To narrow down the list of chemicals, among thousands in the environment, that pose risks to people or wildlife, the US Environmental Protection Agency (EPA) is turning to computational methods . The agency has $2.4 million in anticipated funding for innovative approaches to virtually mimicking the effects of compounds on living organisms. The specific problem the EPA is concerned with at the program's outset is endocrine disruption "There are 87,000 chemicals in the environment. There is a need for improved approaches for prioritizing which chemicals should be screened and tested," explained Elaine Francis, director of EPA's endocrine disruptors research program. "We would not have to test every chemical for effects, and make better informed decisions as a regulatory agency." Computational toxicology also could help cut animal testing, the original reason EPA began pursuing the approach 15 months ago, Francis told The Scientist "I'm very happy to see the EPA coming up with funding to stimulate research in this area. I think we'll be seeing a lot more of these initiatives, for instance, from in NIH," said Thomas Knudson of Thomas Jefferson University, editor of the journal

    Extractions: Endocrine Disruptors Our Stolen Future: Are We Threatening Our Fertility, Intelligence ad Survival? by Theo Colborn, Diane Dumanoski and John Peterson Myers. The Endocrine System The endocrine system acts as the chemical messenger system for communication throughout our body. The main purpose of the endocrine system is to control and regulate body functions especially growth and development. This is accomplished through hormones, potent, biologically-active chemical messengers that in very small amounts can produce significant biological effects. Hormones are released from the brain, thyroid, ovaries, testes and other endocrine glands and then carries them through the bloodstream to the target cells and organs where they activate and regulate various functions. The system is made up of the pituitary gland which acts as a control center telling the ovaries or the thyroid when to send their signals and how much hormone to send. The pituitary gets its cues from another gland, the hypothalamus, which acts as a thermostat telling the pituitary to increase production, slow down or shut off. These messages travel back and forth continuously to keep all parts of the organism operating as one coordinated being. Hormones also guide the growth of a baby’s nervous system and immune system and "programs" organs and tissues such as the liver, blood, kidneys and muscles so they will function properly. During early development this regulation of growth and development is critical for a child. The thyroid hormone, for example, is essential for normal neurological function and development. Deficiencies of thyroid hormones during fetal development or during early infancy can lead to mental retardation, hearing loss and speech problems. Children with thyroid deficiencies, even those with normal IQ’s, can have language comprehension problems, impaired learning and memory and hyperactive behavior.

    http://www.phthalates.org/yourhealth/endocrine.asp
    
    Extractions: Background The endocrine system in humans and other animals has an important job. It produces the hormones that regulate the body's various processes, such as metabolism and reproduction, which are vital to the chemistry of life. One example of a hormone is insulin, which breaks down sugar. Another is adrenalin, which pumps us up so we can deal with stress or danger. Estrogens are hormones that impart female characteristics and androgens impart male characteristics. Endocrine-active chemicals (sometimes called "endocrine disruptors") received wide publicity in 1996 with the publication of a book dramatizing the impact of accidental chemical spills and other isolated incidents on wildlife - and hypothesizing that humans could also be harmed. What gave the book an added fear factor was its emphasis on potential effects on sexual development and reproduction. The book speculated that even extraordinarily low levels of some chemicals, delivered at just the wrong time, could have calamitous consequences on sexual structure, function, behavior and even identity. Some have coined a catchy phrase for such chemicals - "gender benders." The Issue Many things like diet, drugs, exercise, or exposure to beneficial or harmful substances, can alter the operation of the human body, including the endocrine system. The precise issue of how and when the endocrine system can be disrupted, however, is still very murky - as well as anxiety-inducing. Everyone agrees that a few chemicals and some natural substances (for example, soybeans are a weak estrogen mimic), can impact the endocrine system to some degree.

    http://www.environment.no/templates/themepage____3167.aspx
    
    Extractions: Hormones control a whole range of functions in people, animals and plants, and are particularly important for growth and development. We have known for a long time that some chemicals can interfere with the hormone balance in people and animals and have effects similar to those of hormones. They may disrupt the endocrine (hormone) system by mimicking, enhancing or inhibiting the effects of hormones. All types of hormones may be affected, but the focus has often been on possible effects on the functioning of sex hormones, and especially the female sex hormone oestrogen. Oestrogen controls sexual development in the fetuses and young of both people and animals. The presence of endocrine disruptors can cause "feminization" of male animals.

    http://www.nrp50.ch/
    
    Extractions: Summary The presence of endocrine-active chemicals ("endocrine disruptors") in the biosphere has become a worldwide public health and environmental concern. In 1999, a report released by the Swiss Agency for the Environment, Forests and Landscape (BUWAL) concluded that such chemicals have already left a mark in the Swiss landscape and implicated them as a general cause of population changes in wildlife. Some of the chemicals involved (e.g. polychlorinated biphenyls (PCBs) and dibenzo-p-dioxins (dioxins)), have received wide media attention because of their negative health impact on humans. The potential contribution of endocrine disruptors to the increased incidence of a number of diseases and developmental disorders in humans and animals is alarming, but the establishment of solid cause-effect relationships requires scientific clarification.

    Extractions: The Department of Ecotoxicology has validated a sensitive and specific in vitro screening test for oestrogenic chemicals using a recombinant yeast assay. This assay allows for the generation of reproducible empirical biological data to be obtained in a cost-and-time-effective manner. A simple colour change from yellow to red, measured by a spectrophotometer, indicated the presence of an oestrogenic chemical. The intensity of the colour change is directly related to the oestrogenic activity. This assay has been shown to be suitable for both neat chemicals and environmental samples and complements the in vivo mammalian methods also available at SPL . A similar assay for androgenic activity has also been validated. The Department now offers a full range of oestrogen, androgen, anti-oestrogen and anti-androgen screens. Widespread concern exists over environmental contaminants that can mimic the biological activities of the female hormone, oestrogen. A wide range of chemicals has been shown to be weakly oestrogenic. These include both natural chemicals, such as phytoestrogens and mycoestrogens, as well as synthetic chemicals such as pesticides, polychlorinated biphenols, plasticisizers and the degradation products of surfactants. The regulatory response to these concerns has been spearheaded by the US Environmental Protection Agency, which is mandated to screen some 15000 chemicals for endocrine disrupting effects.

These chemicals are called endocrine disruptors because they can interfere with our hormonal system, called "endocrine" by scientists. Some people believe that endocrine disruptors can ruin people's reproductive ability and cause lots of diseases and malformations. They claim that endocrine disruptors are a major threats for the humanity. In the other hand, some skeptics claim that that endocrine disruptors are "just another creation of fear mongering environmentalist leftists". Who knows... except possibly for endocrine disruptor specialists. Regrouped under the WHO (World Health Organization) in a worldwide program called the IPCS (International Programme on Chemical Safety), they have published recently an extensive report giving the state of science on endocrine disruptors. It contains over a hundred pages written in a scientific jargon for endocrine disruptors specialists... nothing for you and me.

    Extractions: March 17, 2003 RSP 2003-05 Summary Research has demonstrated that some chemicals, dubbed "endocrine disruptors," can interfere with animals’ hormone systems, potentially causing adverse health effects. EPA created the Endocrine Disruptors Screening Program (EDSP) to comply with a Food Quality Protection Act (FQPA) of 1996 requirement to screen all chemicals used in pesticides. Thus, EPA should limit the EDSP only to those chemicals for which testing is mandated, and include only those additional chemicals for which low-dose effects have been reported in at least one laboratory animal study in the peer-reviewed literature that used realistic routes of exposure. The first 50-100 chemicals should include a broad universe that samples a range of expected endocrine activity, biochemical modes of action, and toxicity. The selection process should also ensure inclusion of chemicals with widespread human exposure, but for which there are few or no toxicity data.

    Extractions: More HOME REGS. BY ISSUE AREA ... WHAT'S ON YOUR RADAR? Research has demonstrated that some chemicals, dubbed “endocrine disruptors,” can interfere with animals’ hormone systems, potentially causing adverse health effects. EPA created the Endocrine Disruptors Screening Program (EDSP) to comply with a requirement in the Food Quality Protection Act (FQPA) of 1996 that EPA develop a program to determine “whether certain substances may have an effect in humans that is similar to an effect produced by a naturally occurring estrogen, or such other endocrine effect as the [EPA] Administrator may designate.” The FQPA requires screening of all chemicals used in pesticides. The EDSP would prioritize chemicals for screening, and initially screen them for ability to interact with the endocrine system using a set of short-term in vivo and in vitro assays. Chemicals that come up positive in these “Tier 1” assays would go on to “Tier 2” testing—longer-term tests to look for adverse reproductive and developmental effects.
