摘　　要：研究了乙醛对白鲢幼鱼的毒性影响，试验结果表明：乙醛对白鲢幼鱼４８ｈ的半致死浓度（ＬＣ５０）为１４６．１８ｍｇ／Ｌ，安全浓度为１４．６２ｍｇ／Ｌ。该试验结果为制定废水中乙醛的排放标准及水环境中乙醛的污染评价提供了依据。A study on the toxicity of acetaldehyde to larva of hypophthalmichthys molitrix has been carried out.The reslts show that the LC 50 of acetaldehyde for 48h to larva of hypophtalmichthys molitrix is 146.18 mg/L and the safe concentration is 14.62 mg/L,forming a foundation for laying down discharge standard for acetaldehyde-containing wastewater and the assessment of acetaldehyde pollution in water environment.
