Abstract
|
|
|
Objectives: The purpose of this study was to identify the exposure level of airborne hexavalent chromium in the plating industry and the exposure level compared to domestic and international occupational exposure limits.
Methods: A total 92 samples were collected from ten industrial plating sites. Hexavalent chromium samples were collected using a three-stage cassette equipped with a 37 mm, 5 ㎛ pore size PVC filter. The analysis was performed by ion chromatography.
Results: The geometric mean of hexavalent chromium concentration in the plating industry was 0.052 ㎍/㎥, and it was found that the average exposure level was 0.8 times the South Korean exposure limit. When applying the US ACGIH TLV, however, the average concentration was more than twice as high.
Conclusions: The South Korean exposure limit for hexavalent chromium needs to be strengthened due to significant differences in exposure levels according to domestic and international occupational exposure limits. Furthermore, respiratory and dermal sensitization should be labeled.
