Clinical evaluation of 58 organolead manufacturing workers.

Fifty-eight workers were evaluated at a university-based occupational health clinic for potential health effects related to organic and inorganic lead exposures. The clinical evaluation included a history, physical, and laboratory examination, and in a subset of workers, neurobehavioral tests and nerve conduction studies. Workers reported symptoms that predominantly involved the central and peripheral nervous systems. Findings for which no alternative medical explanations could be found included neurobehavioral abnormalities (18 of 39 workers) and sensorimotor polyneuropathies (11 of 31 workers). The clinical presentation and evaluation of workers exposed to organic lead are discussed.
