Title Biological exposure tests for the early detection of lead exposure
Original title Biologické exposiční testy jako časný indikátor zvýšené exposice olovu [in Czech]
Bibliographic information Jan. 1982, Vol.34, No.1, p.19-24. 23 ref.
Abstract Study to determine the value of free erythrocyte protoporphyrin concentrations as an early indicator of lead exposure, in comparison with other exposure tests (blood lead concentration and blood haemoglobin levels, urinary delta-aminolaevulinic acid and coproporphyrins, erythrocyte count, haematocrit). The study covered 230 lead workers (divided into subgroups on the basis of lead exposure levels), 10 persons disabled due to chronic lead poisoning and 44 non-exposed controls. Erythrocyte protoporphyrin levels gave better information about lead absorption than did blood lead concentrations or urinary ALA and coproporphyrin levels. They can indicate a danger of lead poisoning and can be used to assess working capacity following chronic poisoning.
