Major toxic metals: Lead

video

Next, Prof. Liao will introduce lead. How can lead exist in food? In general, plant foods grown in industrialized areas and near freeways contain significantly higher levels of lead than foods grown in remote areas. For animal products, the highest levels of lead are found in bone; as a food group, seafood tends to contain the highest levels of lead.

Generally, lead affects children more than it does adults. Children tend to show signs of severe lead toxicity at lower levels than adults. Lead poisoning has occurred in children whose parent(s) accidentally brought home lead dust on their clothing. Neurological effects and intellectual disability have also occurred in children whose parent(s) may have job-related lead exposure.
