Of course, even if a link to air pollution is not yet proved, that does not mean it can be ruled out. “It’s hard to disagree with the opinion that exposure to neurotoxins and air pollution is bad for our health and that we should be doing more to protect our environment and prevent these exposures,” Maureen Durkin, chair of the Department of Population Health Sciences at the University of Wisconsin-Madison, said in an email. “Credible research into the causal links of these exposures to autism specifically is difficult to do but should be done and critically evaluated to inform environmental policies.”
