http://ehp.niehs.nih.gov/1206187/Objective: Air pollution contains many toxicants known to affect neurological function and to have effects on the fetus in utero. Recent studies have reported associations between perinatal exposure to air pollutants and autism spectrum disorder (ASD) in children. We tested the hypothesis that perinatal exposure to air pollutants is associated with ASD, focusing on pollutants associated with ASD in prior studies.
"Shocking" that pollution is being connected to what amounts to a birth defect. Maybe someday we will "know" the truth.
Results: Perinatal exposures to the highest versus lowest quintile of diesel, lead, manganese, mercury, methylene chloride, and an overall measure of metals were significantly associated with ASD, with odds ratios ranging from 1.5 (for overall metals measure) to 2.0 (for diesel and mercury). In addition, linear trends were positive and statistically significant for these exposures (P < .05 for each). For most pollutants, associations were stronger for boys (279 cases) than girls (46 cases) and significantly different according to sex.
Which is the same thing every other "study" finds. Let me guess, the conclusion will be more "research" is needed.
Conclusions: Perinatal exposure to air pollutants may increase risk for ASD.
After, what, 80 years of dumping pollution into every possible area of life, "it might be possible" the increase in disease is caused by shit dumped into our air, rives, soil, food, drinking water and pretty much anything else we come into contact with? I guess 50 years of "research" isn't enough. I mean, it's "almost impossible" to connect air pollution full of toxicants to illness. More research is "needed". We can't possibly "know" that mercury from burning coal is causing kids to be autistic. It's just so far beyond our current scientific "understanding". Medical science can't measure mercury levels in children, and compare them and figure out what is happening. It's "such a mystery".
