Chemical BPA Linked to Heart Disease Risk

BusinessWeek: "New research raises the possibility that people who have the highest levels of a chemical known as BPA in their urine are more likely to be diagnosed with heart disease.

But the findings don't prove that bisphenol A (BPA) actually causes heart disease -- one scientist even suggests other factors may be at play -- and researchers can't explain why statistics suggest that urinary levels of the chemical dropped by one-third over just two years during the last decade.

Still, the numbers raise more questions about BPA, which is found in a huge variety of plastic products. 'The risks associated with exposure to BPA may be small, but they are relevant to very large numbers of people,' said study author Tamara S. Galloway, a researcher at the University of Exeter in England."
