      다국어 초록 (Multilingual Abstract)

      The exposure level of chromium and nickel for chrome and nickel plating workers were evaluated. Chromium and nickel concentrations in serum from 82 exposed workers and 66 controls, who were not exposed occupationally to metals, were analyzed by flameless atomic absorption spectrophotometry. The results were as follows :
      1. The recovery percent of chromium and nickel concentrations in personal air samples were 95.9-108.2%, 88.0-107.7%, previsions (C.V. %) were 2.7-3.1%, 2.1-4.4%, respectively.
      2. The recovery percent of chromium and nickel concentrations in serum were 93.6-106.4%, 91.3-107.9%, and previsions (C.V. %) were 1.7-7.6%. 2.4-5.4% respectively.
      3. The exposure level of chromium and nickel concentrations in the place of preparation process were 2.0±2.00㎍/㎥, chromplating were 35.7±53.07㎍/㎥, 2.8±3.42㎍/㎥, nickelplating were 4.6±5.8㎍/㎥, 18.62±4.41㎍/㎥, and covering were 2.9±2.02㎍/㎥, 1.1±0.47㎍/㎥ respectively.
      There were significant difference of concentrations for chromium and nickel in workplaces by groups statistically.
      4. Chromium concentrations in serum of exposed group and control were 0.68±0.399 ㎍/l, 1.41 0.748㎍/1, respectively.
      There were significant difference of concentrations for chromium and nickel in serum by groups statistically.
      5. Chromium and nickel concentrations in serum of exposed group were not significant by workplaces.
