研究了铜对缘管浒苔（Ｅｎｔｅｒｏｍｏｒｐｈａｌｉｎｚａ）的毒性效应，试验了不同的配合剂对铜的毒性效应及累积量的影响。结果发现，铜对缘管浒苔的毒性效应阈值为０．１０ｍｇ／Ｌ；０．５０ｍｇ／ＬＣｕ￣（２＋）可使缘管浒苔迅速死亡，培养９６ｈ后光合作用强度下降为零。ＥＤＴＡ可抑制铜在藻体中的累积，缓解毒性；８－羟基喹啉则促进铜在藻体中的累积，加刷了毒性。和铜污染的培养介质短期接触（＜１ｍ后，加入足量ＥＤＴＡ，藻体生长和对照组相当，较长时间接触（＞４ｈ）后，ＥＤ－ＴＡ不能使藻恢复生长。结合ＥＤＴＡ“洗脱”实验提出，Ｃｕ￣（２＋）可能首先经离子交换机制结合于藻体表面，之后，才逐步向细胞内转移。
The toxic effects of copper on Enteromorphalinza were studied, and the effects of different complexing agents on copper toxicity and accumulation were studied. The results showed that the toxic effect threshold of copper to edge tube Enteromorpha was 0.10mg / L; 0.50mg / LCu¯ (2+) could make the edge tube enteromorpha die quickly, and the intensity of photosynthesis decreased to zero after 96h culture. EDTA can inhibit the accumulation of copper in the algae, relieve toxicity; 8-hydroxyquinoline is to promote the accumulation of copper in the algae, plus brushing toxicity. ED-TA could not restore the growth of alga after a short period of exposure (> 4h) after incubation with copper-contaminated culture media for short-term exposure "The experiment proposed that Cu ~ (2+) may first be bound to the surface of algae by ion exchange, and then gradually transferred into the cell.
