Development and application of a sensitive short-time bioassay method for evaluating long-term safety of environmental water

用D. magna，进行了使用浓缩有机物的慢性试验和急性毒性试验。结果表明，D. magna可作为评价河流沃茨长期生态毒性的可靠方法。此外，在慢性试验中观察到的后代的减少率和在急性试验中的抑制效果之间的正相关。本研究结果提示，急性毒性试验可用于短期内预测长期效应。

For evaluating the ecotoxicity of various river water samples by using D. magna, both chronic test and an acute toxicity test using concentrated organics were conducted. As the results, chronic tests with D. magna can be used as a reliable method for evaluating long-term ecotoxicity of river waters. Moreover, a positive relationship was observed between the decrease ratio of offspring in chronic test and the inhibition effect in the acute test. Results of this study suggest that the acute toxicity test can be used for predicting long-term effect in a short term.
