| 摘 要： | 对影响长江口滨岸带河蚬体内重金属富集量的4个主要非生物因子依次进行分析。结果表明,较高温度有助于河蚬对Cu、Zn、Cr、Ni的吸收;盐度对河蚬的重金属累积量影响比较复杂,仅在秋季表现出一定相关性,春季盐度影响不大;河蚬体内Cu含量与沉积物粒径存在显著正相关,Zn与沉积物中有机质含量存在一定正相关,Pb与沉积物中有机质含量存在着负相关;河蚬体内重金属元素两两间的相关性明显,多种元素间的相互作用机理值得进一步探讨。

| Abstract: | Four main abiotic factors which affect the accumulation of heavy metals by Corbicula fluminea along the coastal zone of Yangtze Estuary were analyzed.The results showed that higher temperature did help to accumulate copper,zinc,chromium and nickel by Corbicula fluminica.The effect of salinity to the accumulation of heavy metals was relatively complicated,only showing definite correlation in autumn.The concentration of copper in C.fluminea showed dramatically positive correlation with the particle size of sediment.The concentration of zinc showed definite positive correlation with organic content of sediment,while lead was relative to zinc.The pairwise correlation between heavy metals in C.fluminea was significant.The mechanism of interaction among different heavy metals deserved further investigation. |
