    Common synthetic chemicals suspected of disrupting the hormone system could be responsible for serious health problems, warns a report released on 19 February by the World Health Organisation (WHO) and the United Nations Environmental Programme (UNEP). Nearly 800 chemicals are known or believed to interfere with hormone receptors, synthesis or conversion, according to the report’s authors. But while the vast majority are currently on the market, only a small fraction have been investigated in tests capable of identifying overt endocrine effects, the report concluded. Specifically, the report highlighted associations between exposure to these endocrine disrupting chemicals (EDCs) and non-descended...

    US scientists have come up with a system to assess whether chemists' latest synthetic product is an endocrine disruptor – a chemical that interferes with hormone regulation in animals and humans.As industry seeks replacements for endocrine disrupting chemicals (EDCs), such as bisphenol A and some flame retardants, it often discovers that the replacements are no better, and sometimes worse, than what is being replaced. This is because the replacements have been designed using the same flawed tools as their parent chemicals and because of the lack of adequate EDC testing, say the scientists. Now, a team led by Pete Myers,...

    A new study finds that fetal exposure to the plastic additive bisphenol A, or BPA, alters mammary gland development in primates. The finding adds to the evidence that the chemical can be causing health problems in humans and bolsters concerns about it contributing to breast cancer. "Previous studies in mice have demonstrated that low doses of BPA alter the developing mammary gland and that these subtle changes increase the risk of cancer in the adult," says Patricia Hunt, a geneticist in Washington State University's School of Molecular Biosciences. "Some have questioned the relevance of these findings in mice to humans....

    Ingredient of some plastics and food packaging can interfere with cardiac rhythm Bisphenol A toys with the female heart, a new study finds. And under the right conditions, its authors worry, this near-ubiquitous pollutant might even prove deadly. BPA is a building block of clear hard plastics, dental sealants and the resins lining food cans. Studies have shown that throughout the industrial world, nearly everyone regularly encounters the compound, albeit at trace concentrations. That’s small consolation, says Laura Vandenberg of Tufts University in Medford, Mass.: In the new BPA study, “the most effective dose was very close to — if...

    LONDON (Reuters) – Exposure to a chemical found in plastic containers is linked to heart disease, scientists said on Wednesday, confirming earlier findings and adding to pressure to ban its use in bottles and food packaging. > The analysis also confirmed that BPA plays a role in diabetes and some forms of liver disease, said Melzer's team, who studied data on 1,493 people aged 18 to 74. > U.S. government toxicologists at the National Institutes of Health concluded in 2008 that BPA presents concern for harmful effects on development of the prostate and brain and for behavioral changes in fetuses,...

    More than a decade after Congress directed the US Environmental Protection Agency (EPA) to carry out assessments of endocrine disrupting chemicals, the agency has announced the first set of compounds to be screened under its Endocrine Disruptor Screening Program (EDSP). Endocrine disruptors are chemicals that can affect hormones produced by the endocrine system, which regulate growth, metabolism and reproduction.The EPA has requested that manufacturers screen seven compounds under this  first round, including atrazine - a widely used herbicide that may be associated with birth defects, low birth weight and menstrual problems. Although banned in Europe, atrazine remains prevalent in the US, with...

    Are chemicals in our environment masculinizing girls and feminizing boys? A growing body of scientific evidence suggests that this is the case, and one of the latest studies has linked exposure to a substance known as bisphenol A, or BPA, with aggressive behavior in girls. Liz Szabo reports on the research in USA Today, writing, “In the study of 249 pregnant women, the first to examine the effects of BPA on children's behavior, researchers found that girls ... were more likely to be aggressive if their mothers had high levels of BPA — an estrogen-like chemical used in many consumer...

    Liberals have created a powerhouse propaganda machine that helped smear a four-star general, promotes endless environmental scares and brags it can place its left wing themes in the nation's leading newspapers. Fenton Communications pitches for trial lawyers, collectively the largest contributors to the Democrat Party, as well as for the hard line environmental group Greenpeace; Venezuela's socialist leader Hugo Chavez; anti-war demonstrator Cindy Sheehan; and gay and abortion advocates. Its account executives arrive from such left wing outposts as the office of ultra liberal Rep. Dennis Kucinich, abortion provider Planned Parenthood, the anti-Bush ACLU, Greenpeace and the news media....

    Cumulative effects of phthalates and related compounds will be larger than effects measured one chemical at a time, reports a National Research Council panel On December 18, a National Research Council panel told the Environmental Protection Agency that sufficient data exist to begin assessing the potential health risks posed by phthalates, among the most ubiquitous pollutants on the planet. At the same time, the NRC panel strongly recommended that the agency adopt a “paradigm shift” in the way it assesses the chemicals’ toxicity to humans. Instead of evaluating each phthalate compound individually, EPA should begin assessing risks from likely combos...

    Did you know the cosmetics and body care products you use on a daily basis could be contaminated with chemicals? The Environmental Working Group performed laboratory tests and detected 16 chemicals in blood and urine samples from 20 teenage girls between the ages of 14 and 19. These chemicals are linked to health risks such as cancer and hormone disruption, according to a report released last week by the Environmental Working Group. The group recommends that consumers avoid the following ingredients when purchasing beauty products:

    Just as frogs’ mating season arrives, a study by a Yale professor raises a troubling issue. How many frogs will be clear on their role in the annual springtime ritual? Common frogs that make their homes in suburban areas are more likely than their rural counterparts to develop the reproductive abnormalities previously found in fish in the Potomac and Mississippi Rivers, according to the study by David Skelly, a professor of ecology at the Yale School of Forestry and Environmental Studies. Dr. Skelly’s research found that 21 percent of male green frogs, Rana clamitans, taken from suburban Connecticut ponds are...

    Next time you hear a starling sing, stop and listen hard. It may well be warning of a peril that endangers the whole world of nature - and the very future of the human race itself. For scientists have found that gender-bender chemicals - increasingly contaminating the environment, our food, our water and our bodies - are having a bizarre effect on common birds, causing the males to give voice to longer and more complex songs. This is only the latest in a long series of increasingly urgent alarms being sounded by wildlife against an insidious but devastating danger that...

    In the 1967 film classic The Graduate, a businessman corners Benjamin Braddock at a cocktail party and gives him a bit of career advice. "Just one word…plastics." Although Benjamin didn't heed that recommendation, plenty of other young graduates did. Today, the planet is awash in products spawned by the plastics industry. Residues of plastics have become ubiquitous in the environment—and in our bodies. A federal government study now reports that bisphenol A (BPA)—the building block of one of the most widely used plastics—laces the bodies of the vast majority of U.S. residents young and old. Manufacturers link BPA molecules into...

    Associated Press Health Concerns Resurface Over Chemical Used in Hard-Plastic Polycarbonate Water Bottles ROCHESTER, N.Y., Catching his breath at a fitness club, Matt McHugh took a gulp of water from his trusty, hard-plastic Nalgene bottle and pondered the idea of switching to an alternative made of glass, stainless steel or another kind of plastic. Worries about a hormone-mimicking chemical used in the trendy sports accessory led a major Canadian retailer to remove Nalgene and other polycarbonate plastic containers from store shelves in early December. "It's definitely a concern but I'd like to learn more before I make any decisions about...

    Pollution Suspected Cause of Anomaly in River's South Branch MOOREFIELD, W.Va. -- The South Branch of the Potomac River is as clear as bottled water here, where it rolls over a bed of smooth stones about 230 miles upstream from Washington. But there is a mystery beneath this glassy surface. Many of the river's male bass are producing eggs. Scientists believe this inversion of nature is being caused by pollution in the water. But they say the exact culprit is still unknown: It might be chicken estrogen left over in poultry manure, or perhaps human hormones dumped in the river...
