Children are frequently exposed to toxic metals in the environment, and their developing central nervous system is particularly vulnerable to their effects. This study examined the blood level of heavy metals in children with learning disorder (LD) as compared to children without LD in the United Arab Emirates (UAE). Significantly high blood concentrations of seven heavy metals were found in children with LD. Further analysis using forward stepwise logistic regression showed that molybdenum levels and family history of developmental problems were the best predictors of LD. Our findings suggest the need for monitoring for toxic metals in the environment.
