| 摘 要： | 应用海上围隔实验技术现场模拟了疏浚物倾倒,并对倾倒引起的悬浮物浓度增加对海洋贝类的生态效应影响进行了研究.实验结果显示:倾倒引起的高悬浮物浓度易对贝类生物组织器官造成损害;贝类对疏浚物中溶出的重金属表现出较强的累积能力与一定的选择性,均优先累积Pb,且累积效应显著.海湾扇贝对Zn、Cu、Cd累积较明显,牡蛎对Cd累积较强,Cu、Zn有一定累积;菲律宾蛤仔对Zn、Cu、Cd均有一定累积.扇贝和蛤仔对Hg未呈现累积特征,而牡蛎对Hg有一定累积.倾倒所造成的悬浮物浓度增加直接加剧了贝类对重金属的累积.

| Abstract: | The mesocosm technique was used to study the biological effects of the suspend solid caused by the dumping materials on mollusks. The result showed the suspend solid of high content will be harmful to the construction mollusks. The mollusks show the great capacity of the accumulation metals, and Pb is accumulated firstly. The accumulated Zn, Cu, Cd were main in Argopecten irradirradians, and Cd, Cu, Zn in Crassostrea virginica. Zn, Cu, Cd in Ruditapes philippinarum. The heavy metals in mollusks were from the marine dumping act. |
