A biochemist friend warned me many years ago that our ability to detect chemical substances was improving by an order of magnitude every three years. The environmental movement has long since turned this increasingly sensitive testing into a weapon of war. The cheat is, they don't tell you that the amounts discovered are infinitesimal.

Which is the reason they are finding these things. Before they were undetectable. The real question is what is the tolerance level and how long are they there?
When a mother smokes, takes drugs, or drinks there is a much greater concentration of problematic chemicals than those in the article.
I think the real question is how the human race ever managed to make it to this time. What with eating red meat, spraying with DDT when we were young, parents smoking inside the house, good smelling fumes when filling the tank, no signs telling us that some chemicals are known to the state of California to cause cancer, and the big one, sun tans every summer. Egad I feel old.
