A study in Spain found that children with higher levels of lead, cadmium, copper, and antimony in their urine had increased odds of being diagnosed with attention-deficit/hyperactivity disorder (ADHD). More specifically, higher levels of copper and cadmium were associated with more severe inattention symptoms, while higher levels of copper and antimony were linked to greater hyperactivity-impulsivity severity. The paper was published in the Journal of Attention Disorders.
