The gem-polishing industry in Jaipur, India employs a substantial proportion of children. The process of polishing may result in exposure to chromium in working children. Thus, this study aims to find out the levels of chromium in these working children and the associated factors. Blood samples were analysed for chromium using atomic absorption spectrophotometer. The mean blood chromium levels were 2.51 ± 1.11 mg/100 ml and 2.33 ± 1.10 mg/100 ml in working and school children, respectively, which is well within the permissible levels. However, the practice of employing children should be totally curbed.
