Concentration ratio of coproporphyrine, porphobilinogen and deltaaminolevulinic acid in the urine of workers exposed to lead

Izvršeno je određivanje koproporfirina, delta-aminolevulinske kiseline i porfobilinogena u urinu grupe od sto radnika izloženih olovu. Utvrđeno je da koncentracije delta-aminolevulinske kiseline i porfobilinogena rastu s porastom koncentracije koproporfirina. Zaključuje se da su povišene koncentracije delta-aminolevulinske kiseline i porfobilinogena koristan dodatni indeks povišene apsorpcije olova u organizmu.Concentrations of coproporphyrine, deltaaminolevulinic acid and porphobilinogen were determined in the urine of a graup of 100 workers exposed to lead. It was established that deltaaminolevulinic acid and porphobilinogen concentrations grow with the increase of coproporphyrine concentration. Conclusion has been drawn that increased concentrations of deltaaminolevulinic acid and porphobilinogen present a useful additional index for increased lead absorption in the organism
