地下水中多氯联苯分析方法标准适用性探讨

Discussion on Applicability of Analytical Method Standard for Polychlorinated Biphenyls in Groundwater

针对我国现有地下水中多氯联苯(PCBs)分析方法标准尚不能涵盖地下水质量标准中全部PCBs目标物的标准缺口问题,总结了国内外水中PCBs质量标准和分析方法标准,对比了各分析方法标准在适用介质、PCBs目标物、采样要求、前处理方法、分析方法、方法检出限(MDL)、测量范围和加标回收率等方面的差异,探讨了其PCBs目标物和MDL适用性,确立了我国目前地下水中PCBs分析方法标准的选择策略,提出了完善我国地下水中PCBs分析方法标准的需求和建议。

Focusing on the standard gap problem that the current analytical method standard of polychlorinated biphenyls (PCBs) in groundwater cannot cover all the PCBs target compound in groundwater quality standards in China, the quality standards and analytical methods standards of PCBs in water at home and abroad were summarized. The differences of various analytical method standard in applicable matrixes, PCBs target compound, sampling requirement, pretreatment method, analysis method, method detection limit (MDL), measuring range and recovery were discussed. The applicability of PCBs target compound and MDL were discussed and the selection strategy for the PCBs analysis method standard in groundwater in China was established. The requirements and suggestions for improving the analysis method standard of PCBs in groundwater in China are put forward.
