영문 초록

This study was performed to develope an acute toxicity evaluation model, by Daphnia magna, named as Equitox that imply how many times of pollutant’s toxicity equivalent to reference chemical (K₂ Cr₂ O₇). The method presented in this paper may be applied for control of toxic industrial wastewaters. The experimental results in crude data obtained from D.magna toxicity tests at a given conditions are as follows. 1. In cases of a single toxicant, mobility of D.magna tended to be linearly proportional to the extent of toxic element concentration. 2. In case of a metal surface treatment wastewater, mobility of D. magna showed a curved relation to applied concentrations of wastewater. 3. An acute toxicity evaluation model developed by D.magna， Equitox, is presented, but needed of a standardization in practice. 4. Further studies should be carried out in relation to evaluation of reference chemical toxicity at an optimum condition and to a long term or chronic toxicity evaluation methods.
