通过1998年7月至10月在油坪湾和东京湾进行的为期8周的移植实验，研究了蓝贻贝和绿色贻贝对多氯联苯（PCBs）、滴滴涕（DDT及其代谢物）、滴滴涕及其相关化合物（CHLs）、六氯环己烷异构体（HCHs）和六氯苯（HCB）的吸收动力学。移植后2周，移植贻贝中PCBs和DDTs的浓度水平达到了本地贻贝和牡蛎的水平。DDT相关化合物和氯丹相关化合物的组成也发生了类似于同期天然产物的变化。这一观察结果表明，这些蓝色和绿色贻贝有能力对环境有机氯水平的变化做出快速反应。因此，这些物种可以被认为是了解短期可变污染的良好生物指示剂。在整个移植实验中，蓝贻贝和绿色贻贝的有机氯含量和组成没有显著差异，这表明在海洋污染监测中，不一定要使用单一的贻贝作为生物指示物。
The uptake kinetics of PCBs (polychlorinated biphenyls), DDTs (DDT and its metabo lites), CHLs (chlordane and related compounds), HCHs (hexachlorocyclohexane isomers) and HCB (hexachlorobenzene) were examined in blue and green mussels through the transplantation experiment that was conducted in Aburatsubo Bay and Tokyo Bay in a period of 8 weeks from July to October, 1998. Concentration levels of PCBs and DDTs in the transplanted mussels reached those in native mussels and oysters after 2 weeks of transplantation. The compositions of DDT-related compounds and chlordane-related compounds also changed similar to the native ones with the same period. This observation suggests that these blue and green mussels have the ability to respond rapidly to changes in ambient levels of organochlorines. Thus, these species could be considered as good bioindicators for understanding short-term variable pollution. No significant difference was observed for organochlorine concentrations and compositions between blue and green mussels in the overall transplantation experiment, implying that in marine pollution monitoring, it is not always necessary to use single species of mussels as bioindicator.
