    Question marks have been raised over whether the levels of bisphenol A (BPA) that people are routinely exposed to are high enough to cause the diseases that have been linked to the controversial chemical. An analysis by Justin Teeguarden, a systems toxicologist at the Pacific Northwest National Laboratory, US, makes the bold claim that many of the animal tests that demonstrate that BPA may be a contributory factor in diseases like type 2 diabetes, obesity and heart disease have been elucidated using concentrations much greater than those ever found in humans.‚ÄėThe old saw that correlation is not causation may hold...

    The BPA and body weight controversy heated up again yesterday, with a new Journal of American Medicine Association report that kids with lots of the controversial plastic chemical in their urine are more likely to be obese. ďOur study found ample evidence that BPA exposure makes fat cells bigger, reduces the function of a protein that protects from heart disease, and it disrupts the functional balance of testosterone and estrogen, which are important in maintaining caloric balance,Ē said New York University School of Medicineís Dr. Leonardo Trasande, who traced the levels of Bisphenol A, also known as BPA, in 3,000...

    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. Thatís small consolation, says Laura Vandenberg of Tufts University in Medford, Mass.: In the new BPA study, ďthe most effective dose was very close to ó if...

    A brewing ethical brouhaha at the Milwaukee Journal Sentinel illustrates the hazards of politicized science reporting. In an era of partisan journalism, some have presumed that at least one area of reporting, science, was insulated from blatant bias. After all, there are facts, and it’s presumably easy to identify when data is being cooked. But that's naive, and a brewing ethical brouhaha at the Milwaukee Journal Sentinel underscores how the public can be short-changed when ideology, ambition, or hubris takes precedence over a news organization’s public responsibility to report controversies in context.This incident erupted after a comprehensive review of plastic...

    AP Science Writer Male factory workers in China who got very high doses of a chemical that's been widely used in hard plastic bottles had high rates of sexual problems, researchers reported Wednesday. Heavy exposure to BPA, or bisphenol A, on the job was linked to impotence and lower sexual desire and satisfaction, according to the study, which adds to concerns about BPA's effects on most consumers. The men in the study experienced BPA levels about 50 times higher than those faced by typical American men, said researcher Dr. De-Kun Li. "We don't know" whether more typical doses have similar...

If you're unfamiliar with Bisphenol A (BPA), it is a chemical used to make lightweight, versatile, durable, high-performance plastics.† It's...

    Retailers Pull Plastic Bottles From Shelves Citing Safety Concerns Concerns about the chemical component Bisphenol-A (BPA) lead several major Canadian retailers to pull plastic bottles from their stores today. Chains including The Bay, Zellers, Canadian Tire, Sport Chek and Athleteís World have removed conventional plastic water bottles from their stores following the lead of other retailers including Mountain Equipment Co-op, Lululemon and Aviva Natural Health Solutions. Health Canada is widely expected to officially list BPA, a chemical component frequently used in clear, moldable, polycarbonate plastics, as a potentially dangerous chemical substance as early as today. In the United States, the...

Health Canada made the announcement shortly after a U.S. company said it would stop selling hard-plastic Nalgene water bottles made with bisphenol A because of growing consumer concern over whether the chemical poses a health risk. Health Canada is the first regulatory body in...

    Associated Press A state advisory board on Monday called for a study to determine if sodas and energy drinks containing caffeine pose a risk to pregnant women. The review could lead to warning labels on the drinks under Proposition 65, a 1986 ballot measure that requires the state to identify chemicals that could cause cancer or birth defects. "If I were a pregnant woman or a woman thinking about being pregnant, I would want to know, should I be avoiding caffeine?" said Renee Sharp, a senior analyst with the Environmental Working Group, an environmental research organization that's based in Washington...
  • Programmed For Obesity: Early Exposure To Common Chemicals Can Permanently Alter Metabolic System

    Obesity is generally discussed in terms of caloric intake (how much a person eats) and energy output (how much a person exercises). However, according to a University of Missouri-Columbia scientist, environmental chemicals found in everyday plastics and pesticides also may influence obesity. Frederick vom Saal, professor of biological sciences in MU's College of Arts and Science, has found that when fetuses are exposed to these chemicals, the way their genes function may be altered to make them more prone to obesity and disease. "Certain environmental substances called endocrine-disrupting chemicals can change the functioning of a fetus's genes, altering a baby's...

    Mounting evidence suggests a plastic additive common in baby and sports bottles and used to line the inside of soda and tin cans is accumulating in our bodies at levels far beyond those known to cause considerable health problems in lab animals. At least that's the conclusion in research underwritten by the government or an independent source such as a university, a new review of 115 peer-reviewed publications has found. Industry-sponsored research has so far found no problem with the additive, bisphenol-A. And that, say the authors of a report published in the current edition of Environmental Health Perspectives, contributes...

    WASHINGTON (Reuters) - A common ingredient used to make plastics such as baby bottles causes birth defects in mice -- defects that could also occur in people, U.S. researchers said on Monday. They urged more research into the potential effects of bisphenol A, a chemical long criticized by environmentalists as being a hormone disruptor that could cause defects in embryos. The defects they found, when they occur in humans, can cause miscarriages or mental retardation such as Down Syndrome -- and they seem to be caused at what were considered to be low levels of exposure, the researchers report in...
