Study shows that urinary mercury is not correlated with autism

February 15, 2012 in Autism spectrum disorders

A recent study finds no statistically significant correlation between urinary mercury levels and autism, according to a Feb. 15 report in the open access journal PLoS ONE.

There has been some concern that mercury may play a role in autism development.

To investigate one aspect of this link, Barry Wright of North Yorkshire and York Primary Care Trust led a team of researchers in a study of 56 children with , and mainstream, special school and sibling controls.

The team found that the group with autism did not have elevated or reduced levels of urinary mercury relative to the control groups.

These results indicate that mercury excretion rates are unlikely to have a clear causal link to autism spectrum disorders, the authors write.
