Lead is a neurotoxin that severely impairs cognitive development and intellectual performance in children. It causes blood pressure and cardiovascular diseases in adults in addition to inducing calcium deficiency by replacing calcium in bones. Agriculture, mining and the general chemical industry are increasingly contaminating the environment, resulting in toxic heavy metal(loids) such as lead getting into agricultural food products. The level of environment contamination is not monolithic across the globe, thanks to geography and differences in environmental regulations. However, with the globalized food market, populations in both polluted and non-polluted geographical areas are equally at risk of lead exposure through food. We measured the levels of lead in rice that is imported into the U.S. using XRF and the data was validated using a NIST1568a reference sample. Lead levels ranged from 5.95±0.72 to 11.9±0.6 mg/kg and the calculated Daily Exposure amounts were significantly higher than the Provisional Total Tolerable Intakes for all age groups.
