[Current problems of epidemiology and toxicology of the occupational action of lead (review of the literature)].

The focus of current research on industrial lead toxicity is on 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. To obtain more accurate information on cumulative individual exposure to lead, future research on lead toxicity will increasingly utilize X-ray fluorescence (XRF) analysis for determination of the lead content in bone.
