Current issues in the epidemiology and toxicology of occupational exposure to lead.
Occupational exposure to lead is widespread in the United States. Clinically evident lead poisoning as well as subclinical toxicity occur in populations with occupational lead exposure. The focus of current research on lead toxicity in industrial populations is in the definition of dose-response relationships, particularly at low levels of exposure. Major interest surrounds the development of biochemical and physiologic markers of subclinical toxicity. Need exists to better delineate the toxicity of lead on the peripheral and central nervous system, the kidneys, the cardiovascular system, and the reproductive organs using newly developed markers. To obtain more accurate information on cumulative individual exposure to lead, future research on lead toxicity will increasingly use X-ray fluorescence analysis for determination of the lead content in home.
