Acta Oceanologica Sinica 2013年第2期32卷 76-80页

作者： ZHAng Yuanbiao HUO Yunlong LIU Xiyao KUAng Weiming YUAN Dongxing ji Weidong State Key Laboratory of Marine Environmental Science Xiamen University Third Institute of Oceanography State Oceanic Administration

Concentrations of total mercury （THg） and methyl mercury （MeHg） were determined for 32 surface sed- iments collected along the coastal line of Fujian Province and eastern Guangdong Province. The spatial distributions of THg and MeHg and their environmental impact factors were investigated. The average con- centrations of THg and MeHg in the sediments were 31.5 ng/g and 0.096 ng/g, respectively. Both sediment THg and MeHg concentrations showed relatively high value in the Minjiang Estuary and the coastal areas of Quanzhou and Putian. The concentrations overall decreased as the distance to the shoreline increased. The correlations among environmental impact factors and THg, MeHg were analyzed. The sediment THg concentration was highly correlated to the concentrations of organic matter, copper, total nitrogen （TN） and total phosphorus （TP）, and significantly correlated to pH value of the bottom seawater and concentration of sediment sulfide. The sediment MeHg concentration was highly correlated to the concentrations of organic matter and copper, and significant correlated to the concentrations of sulfide, TN, TP and pH value of the bottom seawater.
