There was a highly inverse significant correlation (negative correlation) between the BLL and full scale IQ (r = - 0. 157) P = 0. 043). As regards to usage of canned food; there was statistical significance high BLL among students with high rate of canned food consumption. Conclusions The problem of the lead pollution in Madinah KSU is not serious because 83. 2% of the studied medical students had BLL less than 10 μg/dl.
