摘要 研究了过氧化氢降解田间农药,并对过氧化氢降解农药的室内生物活性进行测定.结果表明,经H2O2处理后田间农药残留量明显下降,经10 mL/L H2O2 处理1 d后,甲胺磷和毒死蜱的残留量下降率分别为10.57%和16.95%,处理3 d后残留量下降率分别为39.62%和30.49%,而处理7 d后则为45.21%和64.05%.室内生物测定表明,H2O2溶液浸泡处理60 min内,对植物表面的甲胺磷、毒死蜱和久效磷的毒力有微弱降低作用. The efficiency of removal of pesticide residues on vegetables was evaluated by the toxicity bioassay. The results showed that treatment with H2O2 at concentration of 10 mL/L for 1 day, the residue of methami-dophos and chlorpyrifos decreased 10.57% and 16.95%, and the degradation rates were 39.62% and 30.49% at 3 days after treatment, and 7 days later, the degradation rates were 45.21% and 64.05% . The toxicity bioassay of the pesticides on the surface of plant leaf against 3rd-instar larvae of Spodoptera litura showed that treatment with H2O2 for 60 min was able to decrease the toxicity of methamidophos, chlorpyrifos, monocrotophos to a certain extent.
