Mercury levels in fisherman and their household members in Zhoushan, China: Impact of public health
چکیده انگلیسی

Zhoushan Island is situated in the coast of the East China Sea. In order to assess the potential health risks associated with dietary consumption of mercury, hair samples from 59 piscatorial households, thirteen species of fish, crops and poultry samples were collected from the fishing villagers of Zhoushan. Total mercury (T-Hg) and methylmercury (MeHg) concentrations in the fathers' hair (mean, 5.7 and 3.8 μg/g) were approximately 2.5 and 2.1 times greater and 2.6 and 2.0 times higher than those of their wives (2.3 and 1.8 μg/g) and their children (2.2 and 1.7 μg/g), respectively. However, the mean quantity of the fish consumed by the fathers was 2.5 and 2.4 times higher than those of the mothers and children, implying that there was a wide variation in hair Hg concentrations between the fathers and the mothers and children of the same household, which was probably related to the quantity, frequency and type of fish consumed. The average T-Hg and MeHg concentrations in all species of fish were 0.26 and 0.18 μg/g, respectively. Approximately, 15% and 19% of the samples showed T-Hg and MeHg levels which exceeded the limit established by the Chinese National Standard Agency (CNSA) (0.3 and 0.2 μg/g), respectively. However, T-Hg and MeHg levels in crops, poultry, milk, drinking water, food oil and salt samples were all below the corresponding CNSA limit. The estimated total daily dietary intakes of T-Hg and MeHg via different food types showed that fish intake was the major source (> 85%) of Hg exposure. The consumption advisories for the total quantity of thirteen species of fish were 69.3, 58.7 and 15.0 g per day for fathers, mothers and children, respectively.
