title: [Porphyrin equilibrium disorders in subjects exposed to contaminants emitted by nitrogen plants].
abstract: For purpose of investigating porphyrine balance in people exposed to contaminants emitted by nitric plant, porphobilinogen and coproporphyrin excretion with urine was determined. Methemoglobin level in blood was a basis for evaluating exposure to contaminants. The results obtained were compared with the results of investigations done in an adequately selected control group. In people exposed to contaminants emitted by nitric plant increased methemoglobin level and increased excretion of coproporphyrins with urine were found. No significant differences in porphobilinogen excretion were observed.
