By Thomas H. Maugh II Times Staff Writer
Texas researchers have found a possible link between autism and mercury in the air and water.
Studying individual school districts in Texas, the epidemiologists found that those districts with the highest levels of mercury in the environment also had the highest rates of special education students and autism diagnoses.
The study does not prove that mercury causes autism, cautioned the lead author, Raymond F. Palmer of the University of Texas Health Science Center in San Antonio, but it provides a "provocative" clue that should be further investigated. <snip>
California has the highest environmental burden of mercury of any state in the country, and it also has what appears to be the highest rate of autism as well — although some critics attribute this perceived high rate to enhanced surveillance associated with the state's special education program.
Autism is a severe developmental disorder in which children seem isolated from the world around them. There is a broad spectrum of symptoms, but the disorder is marked by poor language skills and an inability to handle social relations. <snip>

The purported link between autism and mercury has been a subject of intense debate. In the past it has centered primarily on the mercury-containing preservative thimerosal, which was once widely used in vaccines.
