Abstract

Regulation of some lead-containing products (e.g., gasoline additives, paint, solder) has reduced some emissions of lead to the environment. This is reflected in reduced aerosol lead concentrations and falloutin both urban and remote regions. It is also evidenced by recent declines in median blood lead (PbB) levels in the US and several European countries. However, those declines in PbB levels are small relative tothe estimated natural PbB level in humans (0.016 mu g dL(-1) or 0.8 nmol L(-1)), and further reductions will be increasingly difficult to achieve because of globally elevated environmental sources of exposure (e.g., food, water, soil, dust). Moreover, despite local changes in lead use and emission patterns, trends over the past decade indicate that national (US) and international lead consumption is not declining. Therefore, international lead use and exposure-control programs are necessary to further reduce global lead poisoning.
