选择了几种生物（口蛤Lutraria rhynchaena、颗粒方舟Anadara granosa、波纹光泽蛤Corrugata和亚洲文蛤Meretrix lyrata）作为研究对象，因为它们具有较高的生物积累性、定居生活和滤食性。在3个地点检测到水中总汞浓度：Lan Ha湾- Cat Ba岛、Hoang Tan公社-广宁省、Dong Bai公社-海丰市。研究结果表明，四种植物组织中的蓄积量不同，但均低于卫生部的允许值（0.5微克/克）。波纹蛤、颗粒方舟、文蛤和卢氏蛤的生物富集系数分别为1.344、344、333和158。这些因素表明，总汞在4种贝类体内的积累具有自然趋势。
Some organisms (snout otterclam Lutraria rhynchaena, granular ark Anadara granosa, corrugated lucine Austriella corrugata and lyrate Asiatic hard clam Meretrix lyrata) were chosen as subjects of this research because of their high bioaccumulation, their sedentary life and their filter feeding habit. Concentration of total mercury in the water was detected at 3 positions: Lan Ha bay - Cat Ba island, Hoang Tan commune - Quang Ninh province, Dong Bai commune - Hai Phong city. Result of this research showes the different levels of accumulation in tissues of 4 species but they are lower than MOH’s allowable value (0.5 micrograms/g). The bioaccumulation factors (BAF) of corrugated lucine Austriella corrugata, Granular ark Anadara granosa, Lyrate Asiatic hard clam Meretrix lyrata and Snout Otterclam Lutraria rhynchaena were 1.344, 344, 333 and 158 respectively. These factors show that accumulation total mercury in 4 species of mollusca is in natural tendency.
