title: [Toxic effects of chloride tributyltin on the predominant phytoplankton species of China coastal sea].
abstract: 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.
