Abstract

Abstract: Collaborative samples of soil and rice were collected to assess the characteristics of mercury pollution and its environmental risk in paddy fields around Wanshan Mercury Mine. The potential ecological risks and human health risks of Hg were evaluated, and the extraction efficiency of available Hg in soils were compared among different extracting agents. Results show that the concentrations of total Hg and MeHg in paddy soils was 0.95-16.27 mg·kg^-1 and 2.06-3.99 μg·kg^-1, respectively. The Hg content in soils exceeded the risk screening values for soil contamination of agricultural land, being moderate and serious level of pollution. Most proportion of soil Hg were in the residue fraction (92.9%-94.6%), and the contents of MeHg only accounted for 0.016%-0.285% of total Hg. The amount of total Hg in rice grain was 27.38-74.29 μg·kg^-1, and exceeded the Chinese national standard limit of 20 μg·kg^-1, but the potential health risk of Hg was low according to the values of probable daily intake (PDI) and target hazard quotients (THQ). The contents of MeHg in rice grain were 27.38-74.29 μg·kg^-1, and the PDI of some sampling sites exceeded the USEPA recommended limit of 0.1 μg·kg^-1·d^-1, suggesting the potential exposure risk of MeHg. Pearson correlation results indicate that the available Hg extracted by 0.01 mol·L^-1 Na₂S₂O₃ and 0.1 mol·L^-1 HCl had significant positive correlations with total Hg and MeHg in soil and rice grain (P < 0.01), suggesting the two agents could be used to estimate Hg availability in paddy soils.

Key words: mercury, methylmercury, paddy field, risk assessment, availability
