摘要

本文对越南红河河口地区四种双壳类动物的不同组织(鳃、套膜、肝胰脏和身体“足”)中的汞含量进行了测定。在本文中，作者确定了软体动物组织中汞含量与组织长度和质量指标以及污染物在溶解、悬浮形式和底部沉积物中的含量的依赖关系。软体动物组织中汞的含量在30.5±1.2 ~ 415.8±6.3 ng/g之间。其中，波氏奥地利菊的肝胰腺中毒性物质含量最高，而柳霉的“足”中毒性物质含量最低。软体动物组织中汞的浓度与底层水层和底层沉积物中汞悬浮形态的含量呈正相关(r为0.68 ~ 0.92,p <0.05)。在研究红河河口区汞的分布时，双壳类可以作为生物监测的对象之一。

MERCURY CONTENT IN BIVALVES AT THE ESTUARY AREA OF THE RED RIVER (VIETNAM)

This article evaluates the content of mercury in various tissues (gills, mantle, hepatopancreas, and body "foot") in four species of bivalves in the estuary area of the Red River in Vietnam. In this article, the authors determine the dependencies of the mercury content in the tissues of mollusks on the indicators of the length and mass of tissues and on the content of the pollutant in dissolved, suspended forms and in bottom sediments. The content of mercury in the tissues of mollusks varies from 30.5±1.2 to 415.8±6.3 ng/g. The highest content of the toxicant was observed in the hepatopancreas of Austriella corrugate, while the lowest was seen in the “foot” of Lutraria rhynchaena. Close, reliable, positive correlations between the concentration of mercury in the tissues of mollusks and the contents of its suspended form in the bottom water layer and in bottom sediments (r from 0.68 to 0.92, p <0.05) were observed. Bivalves can be used as one of the objects of biomonitoring when studying the distribution of mercury in the estuary area of the Red River.
