Elevated blood lead and erythrocyte protoporphyrin levels of children near a battery-recycling plant in Haina, Dominican Republic

A survey of children from a community adjacent to an auto-battery-recycling smelter in Haina, the Dominican Republic, revealed alarming elevations of blood lead (B-Pb) and erythrocyte protoporphyrin (EP-ZnPP) compared with controls. The authors recommend follow-up confirmation and treatment of severely lead-poisoned children, shutdown of the plant, controlled disposal of the hazardous waste from the site, and relocation of the community.
