摘　　要：本研究选用大型蚤(Daphnia magna)作为实验生物,研究了邻苯二甲酸二丁酯(DBP)对其急性毒性作用和慢性毒性作用,同时还研究了环境因素(温度、硬度、腐殖酸)对DBP24h-EC(50)的影响.结果表明DBP对大型蚤的24h-EC_(50)为10.35mg·1^(-1),温度、硬度和腐殖酸对DBP24h-EC_(50)均有一定影响.DBP对大型蚤的捕食行为产生抑制,EC_(50)在 6—7mg·1^(-1)之间.慢性毒性实验结果表明DBP对大型蚤的生长繁殖产生一定影响,低浓度DBP对大型蚤生长繁殖有一定的刺激作用,高浓度DBP对大型蚤生长繁殖存在抑制作用,BDP的最大允许安全浓度为1—2mg·1^(-1).The acute and chronic toxic effects of dibutyl phthalate (DBF) on Daphnia magna were studied. The influence of environmental factors (temperature, humic acid and hardness) on 24h-EC50 was also discussed. The results showed that 24h-EC50 of DBF on D. magna was 10. 35mg·l-1, and the temperature, humic acid and hardness all had influences on the 24h-EC50. DBF influenced the feeding behavior of D. magna, EC50 being 6 -7mg·l-1. The results of chronic test disclosed that low concentration of DBF stimulated the growth and reproduction of D. magna and high concentration of DBF inhabited the growth and reproduction of D. magna. The MATC of DBF was 1-2mg@l-1
