A team of researchers from the City of Hope in Duarte has developed a speedy way to identify drugs and chemicals that can disrupt the balance of sex hormones in human beings and influence the development and progress of diseases such as breast cancer. In a trial screening of 446 drugs in wide circulation, the new assay singled out the popular antidepressant paroxetine (better known by its commercial name, Paxil) as having a weak estrogenic effect that could promote the development and growth of breast tumors in women.

A ubiquitous chemical found in hard-plastic water bottles, DVDs, CDs and hundreds of other common items came under increased pressure Friday when Canada said it might ban the use of bisphenol A in baby bottles because it is potentially harmful. 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 increasing consumer concern over whether the chemical poses a health risk.

Bisphenol A is a chemical found in polycarbonate plastic used to make numerous consumer products. In recent years, studies have suggested that high levels of the chemical stored in the body can lead to adverse health effects. Prenatal exposure is thought to be particularly harmful because the chemical can mimic estrogen. High levels in pregnancy have been linked in some studies to an increased risk of obesity and behavioral problems in children. Research published Friday indicates that bisphenol A levels in pregnant women vary widely.

Exposure to high levels of bisphenol A, or BPA, appears to cause erectile dysfunction and other sexual problems in men, according to a new study by the Kaiser Foundation Research Institute. Funded by the federal government and published in the journal Human Reproduction, the study is the first to examine the impact of BPA on the reproductive systems of men. Previous studies have involved mice or rats. BPA is found in thousands of consumer products, including dental sealants and canned food linings, and has been detected in the urine of 93% of Americans tested.

Four Ohio parents have filed a federal lawsuit against makers of baby bottles, claiming the bottles were made with a harmful chemical that sparked congressional hearings and prompted the world's largest retailer to phase out the products. The complaint filed last week in U.S. District Court alleges the companies knew that bisphenol A was associated with health problems but didn't disclose the risk. It cites scientific studies concluding that BPA, as the chemical is also known, seeps from bottles and sippy-cups into liquid.

SAN FRANCISCO - For more than two decades, Leland Yee climbed the political ladder in San Francisco. A child psychologist turned politician, Yee straddled opposing camps in the city's bare-knuckled political fights, appealing to both right and left and catering to constituents with a strong, attentive staff. Elegant in appearance and charming in manner, he courted financial contributors and built a reputation as a canny pol with an enviable knack of identifying the high-profile issue of the day and then weighing in before a thicket of cameras.

Re "Scientists issue group warning on plastic chemical's hazards," Aug. 3 Reading the comments of Steve Hentges of the American Chemistry Council's polycarbonate/BPA group gave me a profound feeling of deja vu. Hentges' denigration of scientific evidence of the probable health dangers of bisphenol A (BPA) echoed the comments, over years, of "scientists" from the tobacco industry denigrating scientific findings of tobacco's health risks.

Even amid the growing barrage of presumably well-intentioned health warnings now flying around cyberspace, this one is a doozy. It warns that microwaving food in plastic containers releases dioxin, a carcinogen, or cancer-causing agent. The e-mail notes that the warning about dioxin had been sent out in a newsletter from Johns Hopkins, the esteemed medical institution in Baltimore, and that similar information is "being circulated" at Walter Reed Army Medical Center in Washington, D.C.

Male babies exposed in the womb to chemicals that mimic estrogen -- compounds found in birth control pills and some plastics -- are at risk of being born with deformities in their prostate and urethra that may lead to diseases in adulthood, a new study of lab animals has shown. Some researchers say the wider use of the chemicals may have contributed to a surge in prostate cancer in the last two decades, particularly in men under 65.
