Plastic Bottles

The study, published by Dr. Patricia Hunt in the April 2003 issue of Current Biology, reports that exposure to bisphenol A (BPA) causes a chromosomal abnormality in the oocytes or egg cells of female mice. Polycarbonate plastic is manufactured with BPA.

In her study, Hunt, a geneticist at Case Western Reserve University in Cleveland, detected a chromosomal error in cell division known as aneuploidy. Other researches linked aneuploidy to spontaneous miscarriages and birth defects in humans.
