Abstract
 Nematodes offer perspectives for eco-toxicological research as their characters and most
of toxicity assessment focused on Caenorhabditiselegans.In order to enrich the limited numbers of nematodes peciesused for toxicity test,this study assessed the subacute effects of copper and zinc to the life history characters of nematode Acro-beloidesnanus.Compared withcontrol,the72-h effectiveconcentration(EC) ,EC ,and EC50 2010 for reproduction in A.nanus were1.35,0.49,and 0.20mg/L,respectively,for Cuand 829.46,330.29,and163.90mg/L,respectively,for Zn.The EC10 for grow that 72h and 96h of the2nd generation in A.nanus were 1.13 and 0.97mg/L,respectively,for Cu,and 353.46 and284.20 mg/L,respectively,for Zn.During the exposure,the effect of copper¨zinc on reproduction was less than additive,and the copper¨C zinc effect on growth changed from synergistic to antagonistic.
