浙江省猕猴桃主产区果实农药残留水平与评价

以无公害落叶浆果类果品标准为评价标准,对浙江省猕猴桃主产区180个猕猴桃样品中农药残留情况进行了分析与评价.结果表明:浙江省猕猴桃农药品种检出率71.4％,样品农药检出率52.2％.在所检测的7种农药中,敌敌畏、乐果2种有机磷农药均未检出,4种拟除虫菊酯类农药均有不同程度的检出,检出率依次为:氯氰菊酯25.6％,百菌清17.2％,三唑酮12.2％,溴氰菊酯0.56％,杀菌剂多菌灵检出率26.7％,有机磷类农药和拟除虫菊酯类农药来发现超标现象,多菌灵存在超标现象,超标率2.22％.不同产地和取样场所果实中农药残留检出率存在一定差异.经单项农药污染指数和综合农药污染指数评价发现,浙江省猕猴桃未受到农药污染,品质基本安全.

Monitoring and evaluation of the pesticide residues in kiwi fruit in Zhejiang

The pollution degrees of pesticide residues in 180 kiwi fruits of the main kiwi fruit-producing areas of Zhejiang were evaluated by the State non-environmental pollution deciduous fruit berry standards.The results showed that 5 pesticide residues of the 7 pesticides were detectable in fresh kiwi fruits.The detectability rate of pesticide varieties was 71.4%,and sample detectability rate was 52.2%.Dichlorvos and dimethoate were not detected.The pesticide detectability rates of cypermethrin,chlorothalonil,triadimefon and deltamethrin were 25.6%,17.2%,12.2% and 0.56%,respectively.The detectability rate of carbendazim was 26.7%,which exceeded the tolerance of State standards.There were some differences in the pesticide detectability rates in different regions and sampling sites.The detectability rate in the production base was lower than that in free markets.After integrating evaluation into single pollution index and the intergrated pollution index,kiwi fruits were not polluted by pesticides.
