Long-Term Lead Exposure Linked to Heart Deaths: Current OSHA guidelines are probably inadequate, researchers say
Health Day
Exposure to lead over a lifetime may increase the risk of dying from heart disease, new research shows.
Researchers analyzed lead concentrations in the blood and bones of 868 mostly white men from the Boston area who participated in a veterans' aging study.
The men, whose average age was 67 at the start of the study, had lead concentrations in their blood and the bones of the patella (kneecap) and tibia (shin) measured over a nine-year period. During the course of the study, 241 died.
