Abstract

Common analytical methods for detecting and quantifying polychlorinated biphenyls (PCBs) in environmental samples rely on matching a pattern of peaks to a series of Aroclor standards. Due to differences in degradation, partitioning, and metabolism, the PCB pattern in environmental samples can be very different from the Aroclor standards, making identification and quantification of PCBs difficult. To identify an appropriate approach for PCB analyses, the U.S. Environmental Protection Agency Region 9, Biological Technical Assistance Group (BTAG), has considered PCB environmental fate and ecotoxicity, reviewed methods and laboratory capabilities for PCB analysis, and evaluated site-specific data from California and elsewhere. Results of this review indicate analytical methods for routine measurement of specific PCB congeners are currently available, and are cost-effective in comparison with Aroclor-based methods. Accordingly, BTAG has developed a core list of congeners and a phased approach for PCB congener-specific analysis in ecological risk assessments.
多氯联苯同系物及同源物分析在生态风险评价中的应用
检测和定量环境样品中多氯联苯(pcb)的常用分析方法依赖于将峰值模式与一系列Aroclor标准相匹配。由于降解、分解和代谢方面的差异,环境样品中的PCB模式可能与Aroclor标准有很大不同,这使得PCB的鉴定和定量变得困难。为了确定合适的多氯联苯分析方法,美国环境保护局第九区生物技术援助小组(BTAG)考虑了多氯联苯的环境命运和生态毒性,审查了多氯联苯分析的方法和实验室能力,并评估了来自加利福尼亚和其他地方的特定地点数据。本综述的结果表明,目前可用于常规测量特定PCB同系物的分析方法,并且与基于aroclor的方法相比具有成本效益。因此,BTAG制定了一份核心同源物清单和分阶段的多氯联苯同源物生态风险评估分析方法。
