The environmental movement exaggerating something? Oh I simply don't believe it:

Leading toxicologists have warned green groups are "misleading" the public with chemical contamination campaigns.

They said they are deliberately and unfairly scaring the public.

In particular, they criticised a WWF campaign that has highlighted the presence of chemicals in blood, food and in babies' umbilical cords.

And why are we suddenly getting these notices?

The researchers said the chemicals were being found in trace amounts because of advances in detection techniques that could uncover substances at ever smaller concentrations.

Just like if you take a big enough dose of anything it's poison, if you look hard enough you'll probably find trace amounts of anything everywhere.
