Results The micronuclear rate in medium dosage group and high dosage group were significantly higher than that of control group(P＜0.01). The ratio of sperm malformation in middle group and high group were higher than those of controls (P＜0.01).The ratio of sperm malformation increased in dose-dependent manner with dose, a dose-response relationship was found. Conclusion The DBP contamination presents the positive results under the certain dosage to the mouse marrow micronucleus experiment and the spermatozoon abnormal experiment.
