Effect of Two Anionic Surfactants Sodium-Dodecylbenzene Sulfonate (SDBS) and Sodium Dodecyl Sulfate (SDS) on Biochemical Indice in Mytilus galloprovincialis
阴离子表面活性剂SDS和SDBS对紫贻贝生化指标的影响研究

We investigated anionic surfactants concentration in Jiaozhou Bay,China in May and August 2003.Two anionic surfactants sodium dodecylbenzene sulfonate(SDBS) and sodium dodecyl sulfate(SDS) were selected as contaminants to detect their effect on the biochemical indice in Mytilus galloprovincialis.Results show that after 72 days exposing,activities of superoxide dismutase(SOD),catalase(CAT) and induced nitric oxide synthase(iNOS) were significantly inhibited by challenged SDBS(except CAT activity in 0.1mg/L group).Activities of reduced glutathione(GSH),glutathione-S-transferase(GST) and glutathione peroxidase (GPx) were significantly higher than their corresponding control groups under 3.0 mg /L SDS and SDBS.Biochemical indice in Mytilus galloprovincialis were more easily effected by SDBS than by SDS.Statistical analysis suggested that significant positive relationships were found between GST and GPx,iNOS and SOD.But negative relationships were found between GSH and CAT,GSH and SOD under SBDS exposing.iNOS activity in the posterior adductor muscle may be a promising exposed biomarker in Mytilus galloprovincialis for anionic surfactants exposure.
