摘　　要：以平菇为介质，研究了贮藏法、紫外照射法、超声波处理法、臭氧处理和降解酶五种不同处理方法对甲氰菊酯、高效氯氟氰菊酯和吡唑醚菌酯3种农药残留去除效果。结果表明，各种处理对平菇中三种农药均有一定的去除作用，贮藏、紫外照射、超声波处理、臭氧处理和降解酶五种处理方法对3种农药的去除率分别为45.3%~55.2%、26.3%~36.3%、86.7%~96.2%、79.5%~88.1%和21.7%~92.5%。超声波、臭氧处理法去除效果最为理想，紫外照射法对3种农药去除率较低，降解酶仅对甲氰菊酯降解效果好，而超声波和臭氧处理法为去除平菇中甲氰菊酯、高效氯氟氰菊酯和吡唑醚菌酯三种农药残留最理想方法。This paper compares the five methods of （store,UV irradiation,ultrasonic,ozone and degrading enzyme） to remove fenpropathrin,lambda-cyhalothrin and pyraclostrobin residues of Pleurotus ostreeatus. Experimental results show that, five kind of methods all can reduce the Pleurotus ostreeatus of fenpropathrin and lambda-cyhalothrin and pyraclostrobin residues. The removal ratios of fenpropathrin and lambda-cyhalothrin and pyraclostrobin in Pleurotus ostreeatus were 45.3%-55.2%,26.3%-36.3%,86.7%-96.2%,79.5%-88.1%and 21.7 %-92.5 % respectively. Among all these method, ultrasonic and ozone can remove residual pesticide effectively. The three pestcides have been removed much lower with UV irradiation. And the enzyme only degraded fenpropathrin much more. Therefore, ultrasonic and ozone treatment was the ideal method for the degradation of fenpropathrin, lambda-cyhalothrin and pyraclostrobin.
