摘要
目的:监测分析当前贺州市主要蔬菜生产基地及农贸、批发市场中蔬菜有机磷、有机氯和拟除虫菊酯类农药残留情况,寻求相应的预防措施。方法:采用随机与定点抽样的方法采集贺州市主要蔬菜生产基地及农贸、批发市场中蔬菜样本120份,采用气相色谱和气质联谱法测定其中13种有机磷、有机氯和拟除虫菊酯类农药残留。结果:蔬菜中农药残留检出率与超标率分别为16.67%和5.00%(按国家标准),其中,有机磷禁用农药超标数占总超标数的100%;结论:贺州市蔬菜农药残留现象仍然普遍存在,某些地区仍存在农药使用不规范、不科学及超范围用药的情况,应加强管理,有机磷禁用农药残留是导致贺州市蔬菜超标的主要原因。

Methodology： Random sampling in the designated sites in the vegetable producing bases was conducted to collect 120 samples; Gas chromatography and gastity joining flocculus were adopted to test residues of 13 kinds of agro- chemicals such as organic Phosphorus, organic Chlorine and Dalmatian Chrysanthemum Ester remaining on vegetables from the producing bases, free markets and wholesale markets of Hezhou ciaty. Results： Residue contents were up to 16.67%, 5.0% higher than the national standard, of which organic Phosphorus exceeded 100% of the total amount; Conclusion： The phenomenon of residues of agro- chemicals were still very serious, overapplication of agro- chemicals were common in some area.
