| Abstract: | The aim of this research is to verify influences of sample pretreatment on toxic assessment of organic pollutants.Luminescent bacteria P.phosphoreum T3 and Virbrio qinghaiensis sp. Nov Q67 were applied to assay the acute toxicity and river water pretreated with either liquid liquid extraction using dichloromethane or sequestration by a triolein filled semi permeable membrane device (triolein SPMD).The results indicated clearly that substances that lead to stimulating effects influenced the toxic assay performed on original water. After extraction with CH 2Cl 2 or preconcentration with triolein SPMD,acute toxicity of organic pollutants in river water can be monitored.When triolein SPMD was applied,both toxic assays by P.phosphoreum T3 and Vibrio qinghaiensis sp.Nov Q67 gave an accordant result (EC 50,t3 =1.47 EC 50,Q67 +63.16, r 2=0.9848).Based on the comparison,triolein SPMD was recommended for sequestration of organic pollutants from river water for toxic assessment. |
