Paracelsus famously noted that the dose makes the poison.

What did peasants in the 17th century understand about science that modern environmental scientists lack? Skepticism. Modern academics are armed with gavage tubes and cell cultures, and in those, any "toxic chemical" can change hormones.

While I write this, the coffee I am drinking changed my hormones. It's detectable. Have you seen the LD50? It's 10X as toxic as glyphosate, which activists and trial lawyers are suing over in California. (Yes, they are suing over coffee also, California is a good state for anti-science beliefs)

If you are selling fear and doubt, the presence of any pathogen is equal to pathology - if you can detect a molecule in 160 Olympic-sized swimming pools full of water, you can't say it is bad, you can just show it "changes" the water.

You know, like homeopathy.

And that is the problem endocrine-disrupting chemical activists like Pete Myers and Andreas Kortenkamp face. In order for their beliefs to get attention, they have to say Paracelsus is wrong and homeopathy is right. Unless they can convince people that a "cocktail" of harmless chemicals is somehow doing something when the individual chemicals cannot. And that is what Kortenkamp
