The exposure levels of chromium and nickel for chromeplating workers were evaluated. Chromium and nickel concentrations in urine and serum from 82 exposed workers and 69 controls, who were not exposed occupationally to metals, were analyzed by flameless atomic absorption spectrophotometry. The results were as follows:
1. Chromium concentrations in urine of exposed group and control were 3.491±1.83g/g of creatinine, 5.59±2.83g/g of creatinine, and in serum were 0.69±0.30g/ℓ, 2.31±1.16g/ℓ respectively.
There were significant difference of concentrations for chromium in urine and serum by group respectively.
2. Nickel concentrations in urine of exposed group and control were 0.92±0.23g/g of creatinine, 2.20±1.93g/g of creatinine, and serum concentrations were 0.52±0.34g/ℓ, 1.41 ±0.74g/ℓ respectively. There were significant difference of concentrations for nickel in serum by groups statistically.
3. Chromium and nickel concentrations in urine and serum of exposed groups were not significant by workplaces(grinding, electroplants, packaging).
