Occupational lead neurotoxicity: improvement in behavioural effects after reduction of exposure.

Occupational lead neurotoxicity: improvement in behavioural effects after reduction of exposure.

To evaluate critical exposure levels and the reversibility of lead neurotoxicity a group of lead exposed foundry workers and an unexposed reference population were followed up for three years. During this period, tests designed to monitor neurobehavioural function and lead dose were administered. Evaluations of 160 workers during the first year showed dose dependent decrements in mood, visual/m...

Occupational lead neurotoxicity: a behavioural and electrophysiological evaluation. Study design and year one results.

To evaluate the effects of chronic lead exposure on the nervous system in adults, a set of neurobehavioural and electrophysiological tests was administered to 99 lead exposed foundry employees and 61 unexposed workers. Current and past blood lead concentrations were used to estimate the degree of lead absorption; all previous blood lead concentrations had been less than or equal to 90 microgram...

Renal effects of environmental and occupational lead exposure.

Environmental and industrial lead exposures continue to pose major public health problems in children and in adults. Acute exposure to high concentrations of lead can result in proximal tubular damage with characteristic histologic features and manifested by glycosuria and aminoaciduria. Chronic occupational exposure to lead, or consumption of illicit alcohol adulterated with lead, has also bee...

In-vivo determination of lead in the skeleton after occupational exposure to lead.

Lead speciation and occupational exposure.

A field of growing interest in environmental health is that of lead speciation, the study of the various chemical forms of lead. Different lead compounds have different solubilities, which in turn affect bioavailability. Descriptions of lead exposure such as concentrations in air or settled dust are telling quantities, but can only relate part of the story. A variety of biological and geochemic...
