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.

There's a reason wine and spirits are stored in glass: purity of taste. Plastic (and, to a lesser degree, metal) can impart various "flavors" into the liquids it comes into contact with. But that's just one reason that glass is an increasingly popular alternative to plastic and aluminum or stainless steel sport-style bottles. Another is peace of mind. About five years ago, scientists and the Food and Drug Administration started issuing warnings about bisphenol A, commonly called BPA, a chemical used in plastics and in the linings of some metal vessels.

It happened in September but Mike Weflen says it seems like it has been one long day since his wife, Julie, a Bonneville Power Administration worker, disappeared from a remote substation north of Spokane. "I work on it from the time I get up to the time I go to sleep," Weflen, 32, said of the search. "It's the only thing that keeps me going." Weflen, a painting contractor, quit working to spread more than 100,000 posters and buttons with Julie's picture throughout the Pacific Northwest.

The evidence for bisphenol A's negative health effects keeps piling up. In a study released Monday in the Proceeding of the National Academy of Sciences, researchers at the Harvard Medical School reported that the chemical interferes with reproduction in the roundworm Caenorhabditis elegans . Scientists had already shown that bisphenol A, which is used in many plastics and in the linings of food cans , is associated with...

A state panel will not require warning labels on metal cans, plastic bottles and other products that contain bisphenol A, despite more than 200 studies that have linked the chemical to cancer and reproductive problems. Wednesday's unanimous decision may speak to the limitations of the state Environmental Protection Agency's Developmental and Reproductive Toxicant Identification Committee. Dorothy Burk, chairwoman of the committee, acknowledged its reach is limited.

For consumers, a major problem with judging the threat posed by the chemical bisphenol A -- a chemical used in the manufacture of many plastics that can mimic estrogens in the body -- is that researchers disagree about how dangerous it really is. (For more on this controversy, check out the related links to the left.) Now researchers at the University of Missouri-Columbia studying deer mice are shedding light on another way to measure the chemical's effects: Look at subtle changes in animals' behavior and cognition -- specifically, sexually selected behavioral and cognitive traits that drive their ability to find and attract a mate.

Despite a fierce lobbying effort by the U.S. chemical industry, the state Senate narrowly approved a proposal Tuesday that would ban the use of a substance in baby bottles, toddler sippy cups and food containers that independent scientists say is a threat to childhood development. The bill by state Sen.

The U.S. Food and Drug Administration announced Friday that it would not ban the use of bisphenol A, also known as BPA, in food packaging but said it would continue research on the health effects of the widely used chemical. Although it rejected a petition by an environmental group to outlaw the compound in food and beverage containers, the agency did not close the door on future regulation. "This is not a final safety determination on BPA," FDA spokesman Douglas Karas said. "There is a commitment to doing a thorough evaluation of the risk of BPA. " Scientists are still working to determine what effects BPA, which mimics estrogen in the body, has on human health once ingested.

The synthetic chemical bisphenol A has long been found in many household products, but it's just starting to become a household name. Not to mention a hot topic in the scientific community. "Papers about it are being published at the rate of about one a day," says John Bucher, associate director for the National Toxicology Program, an agency of the National Institutes of Health.

Bisphenol A, the chemical used to make some hard-plastic products, has been linked in several studies with health problems in babies and children. A study published Monday again suggests a strong reaction from gestational exposure to the substance. Researchers at Harvard looked at the urine samples of 244 pregnant women in the Cincinnati area. The urine was tested again at birth for the presence of BPA. The children born to these women were also tested for BPA and underwent behavioral evaluations.
