摘　　要：调查了深圳大鹏湾及大亚湾近岸海水及其潮间带动物有机锡的污染状况。结果显示,大鹏湾海水中三丁基锡(TBT)和二丁基锡(DBT)的含量分别为21.13—25.03和10.22—18.68ng·L-1;大亚湾中海水中TBT和DBT的含量分别为nd(低于检测限)—7.63和nd—8.56ng·L-1,所有水样均未检测出单丁基锡(MDT)。大鹏湾潮间带软体动物(近江牡蛎Ostrea rivularis Gould、团聚牡蛎Ostrea glomerata Gould、单齿螺Monodonta labio等)体内TBT、DBT、MDT、三苯基锡(TPT)的含量分别为3.02—26.48、nd—2.65、nd—1.57、13.10—164.08ng·L-1(湿重);大亚湾潮间带软体动物体内TBT、DBT、MDT、TPT的含量分别为nd—17.67、nd—1.50、nd、nd—17.66ng·L-1(湿重)。与国内外其他海港水体和软体动物的调查结果相比,大亚湾受有机锡污染的程度相对较轻,但大鹏湾的污染程度则不容忽视。由此可见,我国应尽早制定法规限制有机锡类化合物的应用。The authors investigate organotin contamination in seawater and marine animals along the intertidal zone at the Dapeng Bay and Daya Bay of Shenzhen.The concentrations of tributyltin（TBT） and dibutyltin（DBT） in seawater of the Dapeng Bay were 21.13-25.03ng·L-1 and 10.22-18.68ng·L-1,respectively.The concentrations of TBT and DBT in seawater of the Daya Bay were nd（lower than the detectable level）-7.63ng·L^-1and nd-8.56ng·L^-1,respectively.Monobutyltin（MBT） was not detected in any of the seawater samples.The concentrations of TBT,DBT,MBT and triphenyltin（TPT） in mollusks,including Ostrea rivularis Gould,Ostrea glomerata Gould and Monodonta labio,from the intertidal zone in the Dapeng Bay were 3.02-26.48,nd-2.65,nd-1.57 and 13.10-164.08ng.g-1（wet weight）,respectively.The concentrations of TBT,DBT,MBT and TPT in mollusks from the intertidal zone in the Daya Bay were nd-17.67,nd-1.50,nd and nd-17.66ng·g^-1（wet weight）,respectively.Comparing the present results with reported data worldwide,it is shown that the coastal water in the Daya Bay was just slightly contaminated by the organotin compounds.However,more attention should be given to the prob-lem of organotin contamination in the Dapeng Bay.Accordingly,legislative restriction is needed on the application of organo-tin compounds in China.
