WASHINGTON (Reuters) -

Children with autism have mercury levels similar to those of other kids, suggesting the mysterious disorder is caused by a range of factors rather than “a single smoking gun,” researchers said on Monday. The researchers at the University of California, Davis, initially found that children aged 2 to 5 with autism had mercury levels lower than other children because the autistic kids ate less fish, the biggest source of mercury that shows up in the blood.
