title: [Determination of delta aminolevulinic acid in urine in a population exposed to lead].
abstract: Uninary levels of delta-aminolevulinic acid (ALA) were determined in 93 workers exposed to lead. Control groups were made up of 32 employees of the same factories of test group and of 24 patients with no history of lead exposure. In the first group, urinary concentration of ALA was 28.55 mg/1; it was 3.36 mg/1 in the second group and 2.98 mg/1 in the other control group. Differences between workers and controls were statistically significant.
