Toxicity Effect Persistent Toxic On Several Kinds Of Marine Life

Ocean of human modern economic development and meet the needs of the people’s welfare aspects isplaying a more and more important role, in recent years worldwide rise of ocean development boom is alsogrowing. At the same time also brought the Marine environment pollution problem, therefore, thedevelopment of Marine must protect the ocean. Persistence to in recent years, because of this, the oceanharmful material to the Marine biological poison, through phoxim, effective chlorine fluorine with ester andTBT and TPT in sea cucumber, scallop and toxic effects of several kinds of algae, describes the severalpersistence harmful substances on the Marine biological toxicity effect; And as the role of biomarkers interms of ecological monitoring. Biological selection experiments for common types, from the individualdevelopment and systematically studied the physiological and biochemical level persistence pests on Marinebiological toxicity effect. The main research contents and results are as follows:1. Phoxim in three kinds of scallops are higher toxicity, toxicity along with the increase of concentrationof phoxim and action time and gradually rising trend. ZhiKong scallops, shrimp scallops, bay scallops in96hLC50were18.662mu g/L,4.916mu g/L,5.65mu g/L. Phoxim on the toxicity of three kinds of scallopschildish shell size order: bay scallop> shrimp yi scallops> ZhiKong scallops. Reveals the half bay scallopshell can be used in some Marine ecological monitoring of environmental pollutants.2. Effective chloric fluorine with ester on trepang high toxicity, toxicity with ester with high chlorinefluorine concentration and action time increases gradually rising trend. According to the method of Bliss, it isconcluded that within24h,48h,72h,96h LC50are:20.850mu g/L,16.084mu g/L,7.786mu mu,5.014g/L g/L. Reveals the trepang young and index of acute toxicity experiment with high sensitivity, clear, simplemethod, conveniently, and the advantages of short experiment period, can be used in some Marine ecologicalmonitoring of environmental pollutants.3. The TBT and TPT stress can produce significant effect to salt the growth of algae, salt algae growsmore slowly. Organic tin salt alga protein content and MDA content has a significant impact; Has asignificant influence on chlorophyll content, the salt alga lipid peroxidation (expressed in malondialdehydeMDA content) can be used as biomarkers of monitoring Marine organotin pollution.4. The toxic effects of Cd2+, Pb2+, in zhanjiang and other whip chrysophyte soluble protein contentreduced. The activity of antioxidant enzymes and REDOX state change is heavy metal lead to algae of theimportant causes of death, lipid peroxide (MDA) in zhanjiang equilateral chrysophyte biomarkers can beused as a monitoring Marine organotin pollution.Conclusion:1. The persistence of harmful substances to the toxic effects of Marine biological effects and aging;Marine life is very sensitive to the toxicity of organic tin, phoxim effect on three kinds of scallops are highly toxic, visible shrimp scallops is sensitive to phoxim most. Explain scallops can serve as indicators of phoximpollution. And knowable ZhiKong scallops LC50> shrimp yi scallops LC50> bay scallop LC50.2. The persistence of harmful substances led to the deaths of the Marine biological process is a processof oxygen stress; The activity of antioxidant enzymes and REDOX state change is organic tin lead to Marinelife of the important causes of death, salt alga protein and lipid peroxidation (MDA) can be used as amonitoring Marine organotin pollution biomarkers.
