disrupt human systems, regulators must ban them  More In This

plastic products we use every day could be interfering with our
hormone systems. Approximately 100,000 synthetic chemicals are
approved for consumer products and industrial processes—and
certain classes of them, it seems, are dangerous to our health.
One compound in the news, known as BPA, is of particular
