The study looked at urine samples of 1,469 U.S. adults, checking their levels of BPA based on how long it was since the subjects last ate. BPA has been thought to be fully eliminated from the human body within 24 hours of ingestion, with half of it being metabolized between four and six hours. However, the research found that the level of BPA present dropped up until eight hours, then leveled off and did not go away. In many cases, subjects who fasted for 15-24 hours had only moderately lower levels of BPA than subjects who ate more recently."

Studies: BPA Lingers in Bodies
GreenBiz.com: "Researchers at New York's University of Rochester say that bisphenol A (BPA) - a chemical found commonly in hard plastic bottles, food storage containers and a wide swath of other products - leaves the body about eight times more slowly than expected.

Don't throw it all away
Montreal Gazette: "While I recycle diligently at home, I must confess that I have tossed my share of refundable cans and bottles into the trash when given no other convenient option. (At this point you may be wondering, what is one of the Gazette's Green Life columnists doing drinking pop out of cans or plastic bottles? Why is she creating unnecessary waste? What about the Bisphenol A lining the can and its possible adverse health effects? And why doesn't she plan ahead, and carry a thermos of coffee and/or an aluminum bottle filled with tap water wherever she goes? Here is where I remind readers that we here at Green Life do not claim to be perfectly green, only trying to move in that direction."
