"As scientific evidence mounts against bisphenol-A, a chemical used in plastic baby bottles, soup cans and other containers, many states -- including Maryland -- are starting to take action to limit the chemical ahead of any federal regulation.

The states are responding to some scientists, consumer groups and now even federal officials who have been sounding alarms about the chemical better known as BPA, which has been linked to developmental disabilities in children and reproductive problems in women.

Minnesota and Connecticut, Chicago and four counties in New York have banned BPA in baby bottles and sippy cups. Maryland is among 20 states that are considering legislation, according to the consumer group Maryland PIRG."
