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.

"The fact that we were able to detect similar effects of phthalate exposure on the function of central neurons for the low and 10-fold higher environmental concentration tested is important in this context: humans get exposed to phthalates mostly through ingestion and their indoor environment, while fish in this study got exposed to phthalates through the surrounding water. These differences in exposure may mean that humans generally take up fewer phthalates from the environment than the fish in the present study. However, even if fewer phthalates are taken up and reach/cross the BBB in humans, it must be assumed on the basis of our results that the effect could still be similar to that observed in our experiments on goldfish. "

It seems sloppy not to attempt to address the relevance of typical human exposure to the study amounts?

Now, for fun, plot the percentage of people exposed to toxic amounts over a map.
