【摘要】 从⁶⁵Zn为示踪元素,进行了⁶⁵Zn从褐指藻到贻贝的传递实验。实验进行了5天。结果表明:（1）贻贝从藻中累积锌的能力比直接从海水中累积锌的能力高41.5～72.0倍;（2）⁶⁵Zn从褐指藻到贻贝有明显的传递,实验第5天时的传递比率为6.18％;（3）在实验过程中,贻贝体内锌的贪量从未超过藻中的锌含量。更多还原

【Abstract】 An experiment on the transfer of zinc from marine unicellular algae Phaeo-dactylum tricornutum Bohlin to Mussel Mytilus edulis L. was carried out by using 65Zn as a tracer element during 5 days. The results show: 1. the ability of the mussels to accumulate zinc from the algae is 41.5 to 72.0 times higher than that of directly from sea water; 2. there is a transfer coefficient of 6.18% on the fifth day of the experiment; and 3. the amount of zinc in the mussels, however, never exceeds that in the algae during the experiment.更多还原
