| 摘 要： | 悬浮颗粒物在水生态系统中普遍存在,为了研究悬浮颗粒物对氯酚类化合物生物毒性的影响,以高岭土为模拟悬浮颗粒物,考察了不同浓度的悬浮颗粒物(0、25、50、100、250和500mg·L~(-1))存在条件下五氯酚钠(NaPCP)对鲫鱼(Carassius auratus)的毒性效应。等温吸附实验结果显示,悬浮颗粒物对水体中五氯酚钠的吸附作用不明显(P>0.05)。96h急性毒性实验结果显示,五氯酚钠对鲫鱼的96h-LC_(50)随颗粒物浓度(SS])的增加而减小,两者间的关系为LC_(50)=146.7exp(-SS]/186.8)+121.7,r~2=0.99。等效线图法评价结果表明,悬浮颗粒物可增强五氯酚钠对鲫鱼的急性毒性,两者呈毒性增加作用。 |

| Abstract: | Suspended particles are ubiquitously distributed in aquatic ecosystem.In order to investigate the influence of suspended particles on biological toxicity of chlorophenols,the kaolinite was used as a model for suspended particles,and acute toxicity of sodium pentachlorophenol(NaPCP) to Carassius auratus was studied at different concentrations of suspended particles(0,25,50,100,250 and 500 mg·L~(-1)).The isothermal adsorption experiments revealed that NaPCP could not be significantly adsorbed onto suspended particles(P >0.05).Acute toxicity results showed that 96 h-LC_(50) of NaPCP to Carassius auratus decreased with increasing the concentrations of suspended particles.The relationship between the value of 96 h-LC_(50) and the concentration of suspended particles(SS]) could be described by the following equation:LC_(50)=146.7exp(-SS ]/186.8)+121.7,r~2=0.99.Results of isobole analysis demonstrated that suspended particles could potentiate the toxicity of NaPCP to Carassius auratus in a synergistic manner. |
