Abstract Blood lead concentrations (PbB), erythrocyte δ-aminolaevulinic acid dehydratase (ALA-D), blood haemoglobin and urinary δ-aminolaevulinic acid (ALA) were determined in 2,245 workers from 30 types of work. The PbB levels found are tabulated. Median values per 100ml blood were: brass foundry, 79µg; lead scrap melting, 79µg; storage battery manufacture, 66µg; shipbreaking, 49µg; crystal glass manufacture, 41µg; car radiator repairing, 37.5µg; PVC manufacture, 37µg. In all these industries there was a definite danger of clinical lead poisoning. ALA-D activity gave a fairly good estimate of PbB, and is especially suitable as a screening test. Blood haemoglobin is useful in monitoring lead exposure only if a series of measurements is available. Recommendations for regular health examinations of lead-exposed workers are given. If PbB values exceed 40µg/100ml, annual determination of ALA is also recommended. If several values exceed 70µg/100ml, the workers should be examined at least 6 times a year. Detailed summary in English.
