The public health dilemma, then, is what policy to pursue in the face of incomplete information. Industry argues it can never absolutely prove the safety of chemicals, but others argue the policy is skewed in favor of industry at the expense of potential health effects. It's very difficult to prove that a chemical is a public health threat because we just can't do the experiments on humans. Every experiment you do is an approximation. I think the goal should be that no child should be exposed until we know it's safe.
Chemicals make the world go 'round.
We could go back to the Stone Age. Industry representatives argue that current testing for Bisphenol-A are more than adequate. The bulk of tests has focused on how much of it leaches into food and drink, and the results vary widely. Some studies indicate no measurable leaching, and in others, industry and regulators dismiss the amount of BPA migration as minimal under normal use. The concern over endocrine disruptors stems in part from the cautionary tale of DES, a potent estrogen given to millions of pregnant women beginning in the late 1930s.
