There have been a lot of posts about the autism-mercury connection on Strollerderby of late, and a lot of skepticism on the part of a lot of readers because of a lack of compelling scientific evidence to support this theory.
Now, courtesy of The University of Texas Health Center, here it is.
Researchers compared Texas school district data on autism prevalence to industrial mercury-release data and found that students who lived closer to pollution sites were significantly more likely to develop autism than those who lived farther away. With every ten miles of distance from the mercury source, community autism rates dropped by 1-2 percent.
The study was published in the journal Health & Place. Researcher Raymond F. Palmer claimed the results "further the association between environmental mercury and autism . . . This study was not designed to understand which individuals in the population are at risk due to mercury exposure, however, it does suggest generally that there is greater autism risk closer to the polluting source."
These results can't help but bolster the claims of parents who believe their children's autism was caused by thimerosal, the mercury-based preservative that has recently been phased out of most childhood vaccines. After all, if children are more likely to develop autism from breathing mercury-tainted air, how much more dangerous is it to inject mercury directly into the bodies of those children?
