"Mercury Pollution, Autism Link Found - U.S. Study"
SAN ANTONIO, TEXAS -- Mercury released primarily from coal-fired power plants may be contributing to an increase in the number of cases of autism, a Texas researcher said on Wednesday."The main finding is that for every thousand pounds of environmentally released mercury, we saw a 17 percent increase in autism rates," she said in an interview.
About 48 tons of mercury are released into the air annually in the United States from hundreds of coal-burning plants.
The study looked at Texas county-by-county levels of mercury emissions recorded by the government and compared them to the rates of autism and special education services in 1,200 Texas school districts, Miller said.
"The study shows that there may be a very important connection between environmental exposure to mercury and the development of autism," she said in an interview.
The U.S. Centers for Disease Control has said it does not know how many cases of autism there are in the country or whether the number has increased, but that the issue is under study.
Some experts estimate there are 1.5 million people in the United States with autism, most of them children, and say the number of cases has risen rapidly in recent years.
