Exposure to phthalate compromises brain function in adult vertebrates

Obviously this is baseless speculation, but I sure do wonder if various psychological conditions that are so diverse and hard to pin down (i.e. 3 out of these 9 symptoms around attention, social behavior, or impulse control) are ultimately just going to be proven to be purely biological. And since genetics can only explain less than half of it, it sure seems that something messing with chemical signaling would be a reasonable explanation for the rest.

I've been speculating on industrial pollutants that act as endocrine disruptors for years now, and every so often some evidence emerges. People understandably don't like such mundane explanations when they've built large parts of their identity around the issues it may have caused them though.
