Bisphenol-A (BPA) is used in polycarbonate plastic baby products. Environment California's report, "Toxic Baby Bottles," in 2007 questioned the safety of this chemical. Study found this hormone-disrupting chemical was found to be leaking from baby bottles. Earlier studies have already shown harmful effects of this chemical.

Suffolk County legislature passed a rule on Tuesday to ban the use of the chemical BPA in baby bottles and sippy cups sold for use by children under 4.

Officials claim that if the measure receives final approval it would be the first of its kind in the U. S.

This deadly chemical has already been banned by Canada. FDA said it was doing research regarding safety of this chemical.

UT grad Brodwick at thinkbaby(thinkbabybottles. com) said: "The media attention has helped bring the issue to the forefront. It was probably Canada's ban of BPA, though, that caused sales to escalate dramatically."

"Many states are in the process of banning the chemical, and we're seeing a lot more interest from the government in reviewing chemicals, especially when they are to be used by little ones."
