| Abstract: | To study the antioxidant and neural responses of marine organisms exposed to tributyltin chloride(TBTCl),the semi-static toxicity test with different concentrations of TBTCl was conducted to determine median lethal concentration and biochemical indices of juvenile crimson snapper(Lutjanus erythopterus) after exposure of 6,24,48 and 96 hours,respectively.The results showed that:(1) The 24 h-LC50,48 h-LC50 and 96 h-LC50 of TBTCl for juvenile crimson snapper were 29.05,22.95 and 19.92 μg·L-1,respectively.Therefore,TBTCl was estimated to be a kind of high-toxicity pollutant for aquatic organism.(2) All physiological and biochemical indices differed in their sensitivity and timeliness of response to TBTCl,among which,SOD activity was most sensitive,followed by AChE activity and MDA content.The effects of TBTCl on AChE activity and MDA content were more obvious during the early stage of TBTCl exposure.(3) Changes of antioxidant enzymes were different between liver and gill.The SOD activity and MDA content in liver tissue were inhibited firstly,then promoted and afterwards inhibited.However,the activities of the two antioxidant indices in gill tissue were promoted and then were inhibited subsequently.The obvious toxic effect of TBTCl on biochemical indices of juvenile crimson snapper indicated that these indices such as SOD and AChE were good biomarkers for monitoring organotin pollution,and more attention must be paid to the potential hazards to inshore fishery resource and ecological safety. |
