Abstract: Nereis diversicolor is an ecologically keystone species of invertebrate that lives in the mud of marineterrestrial interlaced zone.This species can accumulate a large number of toxic heavy metals such as copper,cadmium and zinc in its body,and thus,shows a high endurance against toxic heavy metals.This paper summarized the latest research advance at home and abroad in the characteristics and mechanisms of N.diversicolor endurance against heavy metals and organic contaminants.N.diversicolor could achieve its heavy metals-endurance through several eco-chemical processes,e.g.,mucus secretion and contaminants excretion.The former could form a protective layer or integrate with dissolved ions of pollutants,and thus,decrease the bioavailability of pollutants,while the latter could lessen the pollutants^,bio-toxicity.More researches believe that the toxic heavy metals in N.diverdicolor body are stored in non-toxic physicochemical forms,i.e.,bound to metalbinding protein,such as metallothionein (MTs),metallothionein-like proteins (MTLP) and cytosolic heat-stable thiolic compounds (CHSTC),or incorporated into insoluble deposits or granules.The pivots of future researches on the ecotoxicology of N.diversicolor and its endurance mechanisms against pollutants were proposed.
