ANCHOR LEAD: ENVIRONMENTAL EXPOSURE TO LEAD CONTINUES TO BE A PROBLEM, ELIZABETH TRACEY REPORTS
Even though lead has been taken out of gasoline in most parts of the world and is no longer a component of most paints, lead exposure and accumulation in the body continues to be a problem, with current research showing that even levels previously considered tolerable have deleterious effects on the brain. Tomas Guilarte, a lead expert at Johns Hopkins, uses an animal model to study low level lead exposure.
GUILARTE: The levels of lead that we exposed these animals are in the environmental range, these are levels of lead that continue to be measured in children here in the United States and there’s a very high percentage of children throughout the world that have levels of lead comparable to the ones that were given to these animals. :20
Children are especially sensitive to lead exposure. Guilarte recommends periodic testing of all children for their blood lead level. I’m Elizabeth Tracey reporting.
