Dangerous Plastics:The BPA Problem
Rodent studies of bisphenol A, used in polycarbonate bottles, food cans and other products, have linked the synthetic estrogen to a host of human diseases. Scientists say the chemical can alter cell behavior at very low levels -- in the parts per trillion range -- yet humans are consistently exposed to BPA at levels 10 to 100 times greater.Time to Give BPA the Boot?

First Slide: Which Products Have It
Which Products Contain BPA
BPA is found in the resin in can linings, in the polycarbonate in baby bottles, in dental sealants and elsewhere. The longer a liquid sits in a container made of BPA, the more BPA can leach into the product.

When Worst Leaching Occurs
As we wash polycarbonates such as baby bottles in hot water or heat them in the microwave, more leaching of BPA can occur. The hotter the liquid in a container, the more BPA can leach. The older the container, the more BPA can leach.

Who's Most at Risk
Scientists say fetuses and infants are especially at risk because they are still developing major parts of their body and BPA can alter how their genes are activated. In experiments that looked at the reproductive systems of rodents -- which scientists say are comparable to humans -- doses similar to what a newborn would ingest from a bottle caused cells to divide at a faster rate and led to enlarged prostates and, eventually, prostate cancer.

How to Avoid BPA
BPA is found in polycarbonate plastic, including most shatterproof baby bottles and sports water bottles, toys, dental sealants, food cans and microwavable food containers. Some of these products are available without BPA. Consumers can also avoid any No. 7 plastic, which typically contains BPA.
Next: Retailers Take Action
Toys 'R' Us announced Monday that it will phase out bottles and other "baby feeding products" containing BPA by the end of the year. Wal-Mart last week said that it will stop selling baby bottles made with BPA by early next year.More Retailers Ban BPA
Nalgene, which makes plastic water bottles popular with hikers, and Playtex, which makes a variety of baby products, also say they'll stop using BPA, an ingredient in polycarbonate plastic.

Keeping Baby BPA-Free
Stanford University pediatrician Alan Greene, author of 'Raising Baby Green', encourages parents to reduce their children's exposure to BPA. "I wouldn't use it for my children," says Greene, a father of four.

The American Chemistry Council, an industry group, notes that BPA has been used safely for decades and is an important ingredient that makes plastics flexible and shatter-resistant.An Opposing View
And Rick Locker, an attorney for the Juvenile Products Manufacturers Association, says parents can be confident that products made with BPA are safe. Locker notes that the Food and Drug Administration has not found that BPA poses a risk to children.
