| pubmed-article:8170373 | pubmed:abstractText | The authors present the results of a study of occupational exposure to carcinogenic metals: arsenic, nickel and chromium in four nonferrous plants. Air samples were collected from workplaces of a high potential exposure and measured by GFAAS (graphite flameless atomic absorption spectrometry). On the basis of the results obtained, potential health effects of exposure were assessed by comparing concentrations of arsenic, nickel and chromium with hygienic standard values and assessing cancer risk. It was found that concentrations of arsenic, nickel and chromium, expressed by geometric means, were lower at workplaces than hygienic standard values. A relative cancer risk induced by the occupational exposure to nickel and chromium was comparable with a relative cancer risk of environmental exposure of the population living in the Katowice region while in the case of arsenic, cancer risk was almost 50 times higher. | lld:pubmed |
