Abstract

A multiresidue method for determination of 15 organochlorine pesticides (OCPs), six polychlorinated biphenyls (PCBs), and seven organophosphorus pesticides (OPPs) is implemented for routine determinations of residues in honey. The method involves solid-phase extraction cleanup and determination by GC-ECD/NPD. Quantitation limits ranged from 0.1 to 0.6 microg kg-1 honey for OCPs and PCBs, and from 5.0 to 25.0 microg kg-1 honey for OPPs. Recoveries of OCPs ranged between 77.4 and 94.0%; for PCBs they were from 63.8 to 73.5%. Recovery assays for OPPs varied from 66.7 to 98.1%. The method was applied to the analysis of 111 honey samples from Aragon, Spain. The results obtained indicated a low level of contamination by pesticide residues and PCBs, which can contribute to ensuring the consumer has a safe wholesome supply of honey.

摘要

采用一种多残留方法测定蜂蜜中的15种有机氯农药（OCPs）、6种多氯联苯（PCBs）和7种有机磷农药（OPPs），用于蜂蜜中残留物的常规测定。该方法包括固相萃取净化和气相色谱 - 电子捕获检测器/氮磷检测器测定。OCPs和PCBs的定量限为0.1至0.6 μg kg⁻¹蜂蜜，OPPs的定量限为5.0至25.0 μg kg⁻¹蜂蜜。OCPs的回收率在77.4%至94.0%之间；PCBs的回收率为63.8%至73.5%。OPPs的回收率测定值在66.7%至98.1%之间。该方法应用于西班牙阿拉贡地区111份蜂蜜样品的分析。所得结果表明农药残留和PCBs的污染水平较低，这有助于确保消费者获得安全健康的蜂蜜供应。
