Toxic effects of tributyltin (TBT) on the growth, peak diameter and photosynthetic activity (F(v)/F(m)) of fifteen predominant phytoplankton species in China coastal sea of Leptocylindru danicus, Skeletonema marinoi, Asterionella japonica, Bacilaria paxillifera, Chaetoceros debilis, Chaetoceros socialis, Thalassiosira, Amphidinium carterae, Karenia mikimotoi, Prorocentrum minimum, Gymnodinium sp., Scrippsiella trochoidea, Gymnodinium simplex, Prorocentrum triestinum and Heterosigma akashiwo were systematically studied. 96 h-EC50 of TBT were 136.42, 3.55, 3.15, 2.95, 1.90, 1.08, 0.70, 21.60, 7.71, 4.77, 3.81, 2.04, 0.53, 0.51, 1.76 microg/L, respectively. The no detectation effect concentration were 112.62, 1.19, 1.17, 3.70, 0.95, 1.07, 0.80, 6.28, 1.84, 0.99, 3.73, 1.63, 0.23, 0.16, 1.76 microg/L, respectively. The results indicated that the toxic effects of TBT were very different among different phytoplankton species and the resistance of Leptocylindru danicus was stronger than those of other microalgae. The TBT not only inhibited the growth of phytoplankton, but also changed the peak diameter and decreased the photosynthetic activity (F(v)/F(m)). Besides that, we infer that there may have a relationship between the toxicity of TBT and the composition of predominant phytoplankton population in harbour.
研究了三丁基锡（TBT）对中国沿海15种优势浮游植物，即丹麦细柱藻、海洋骨条藻、日本星杆藻、扇形藻、柔弱角毛藻、聚生角毛藻、海链藻、卡氏前沟藻、米氏凯伦藻、微小原甲藻、裸甲藻、锥状斯氏藻、简单裸甲藻、三角原甲藻和赤潮异弯藻的生长、最大直径和光合活性（F(v)/F(m)）的毒性效应。TBT的96小时半数有效浓度（EC50）分别为136.42、3.55、3.15、2.95、1.90、1.08、0.70、21.60、7.71、4.77、3.81、2.04、0.53、0.51、1.76微克/升。无可见效应浓度分别为112.62、1.19、1.17、3.70、0.95、1.07、0.80、6.28、1.84、0.99、3.73、1.63、0.23、0.16、1.76微克/升。结果表明，TBT对不同浮游植物种类的毒性效应差异很大，丹麦细柱藻的耐受性强于其他微藻。TBT不仅抑制浮游植物的生长，还改变最大直径并降低光合活性（F(v)/F(m)）。此外，我们推断TBT的毒性与港口优势浮游植物种群组成之间可能存在关系。
