* " **Prenatal exposure to lead during the third trimester has significant

impacts on childhood intellectual development, with lasting and possibly

permanent effects.* The study, carried out in Mexico City, found no

evidence of a threshold. The steepest part of the dose-response curve

was within the first few µg/dL of blood lead, indicating that much of

the damage is already occurring at the lower levels of exposure. " (1).
