Lead poisoning in galena miners

Autori razmatraju mogućnost trovanja kod rudara koji kopaju olovni sulfid, Pregledana su 233 radnika i urađene su hematološke pretrage.·Iznesene su toksikološke analize olova u krvi, olova i koproporfirina u mokraći. Ovi rezultati su statistički obrađeni i upoređeni sa drugim grupama: stanovnicima Beograda i sela Donji Dobrić koji nisu eksponovani olovu, zatim sa stanovnicima sela Malo Rudare koji zbog komunalno-higijenskih prilika dolaze u dodir sa olovnom prašnom i olovnim oksidom. Utvrđeno je da postoji značajna razlika (P > 0,01) između· aritmetičkih sredina olova u krvi, olova i koproporfirina u mokraći kod kopača galenita, stanovnika Beograda i sela Donji Dobrić s jedne strane i stanovnika sela Malo Rudare s druge strane. Eksperimentom je razmotrena teoretska mogućnost nastajanja trovanja olovom kod radnika koji kopaju galenit.The authors have considered the possibilities of poisoning in galena miners. 233 workers were examined and hematological analyses were performed. The results of blood lead, urinary lead and coproporphyrin analyses are compared with those obtained in the control groups: the inhabitants of Belgrade and the inhabitants of the village Donji Dobric who are not exposed to lead, and the inhabitants of the village Malo Rudare who are exposed to lead fumes and dust. The village M. Rudare is situated about 500 meters from the lead smelting plant. There is a significant difference (P > 0,01) between the means of blood lead, urinary lead and coproporphyrin in the galena miners, the inhabitants of Belgrade and D. Dobric on the one hand, and the inhabitants of the village M. Rudare on the other hand. The possibility of poisoning of galena miners was also considered by the experiments »in vitro«
