摘要： In 1963, selenosis occurred in Yutangba Village, Enshi City, China. Subsequently, local residents migrated to a new area of Yutangba to avoid high selenium (Se) exposure. In this study, 19 soil samples, 43 food samples, 60 hair samples and 58 plasma samples from local residents were randomly collected in New Yutangba Village. The mean total Se concentrations in cultivated soil samples were 1753.6 +/- 742.8 mu g/kg (n = 14). The estimated daily Se intake in New Yutangba Village decreased to 63.2 +/- 39.8 mu g/day, slightly higher than the recommended dietary Se intake for adults in China (60 mu g/day). The mean Se concentrations in hair and plasma samples were 549.7 +/- 165.2 mu g/kg (n = 60) and 98.4 +/- 32.1 mu g/L (n = 58), respectively. The result indicated that appropriate activities, such as relocation, consuming a mixture of local foods and market foods containing low Se concentration, could effectively reduce the risk of high Se exposure.
