脐橙和蜜桔农药残留调查及风险评估

Pesticide Residue Investigation and Risk Assessment of Navel Orange and Orange

调查江西省脐橙和蜜桔的农药残留情况并进行风险评估。对江西省2013年脐橙和蜜桔的144个送检样品中的36种农药残留进行定量检测分析。2013年9月至12月江西省的脐橙和蜜桔质量安全较为稳定,农药残留超标率为0。毒死蜱、啶虫脒、杀扑磷、抑霉唑4种农药有检出,12月份抑霉唑的检出率最高。3个月的农药安全指数均小于1,说明检测的36种农药均在可接受的风险程度内,没有安全风险。本研究可为江西省脐橙和蜜桔质量安全监管提供参考。

The aim was to investigate and estimate risk of pesticide residue in navel orange and orange in Jiangxi province. 36 pesticides residues in 144 samples of navel orange and orange in Jiangxi province were determined by quantitative analysis. The results showed that the quality of navel orange and orange in Jiangxi province is stable and safety from september to october in 2013. Pesticide residues over standard in navel orange and orange were zero. Chlorpyrifos,acetamiprid,methidathion,imazalil were checked out,the detection rate of imazalil is highest in December. Safety indexes of all pesticides were lower than 1 in each sample during three month,showing that 36 pesticide residues were safe. The paper provides a theoretical basis for supervising navel orange and orange safety in Jiangxi province.
