Halogenated organic contaminants, including legislated and potential persistent organic pollutants and their precursors, represent a major environmental concern due to their hazardous effects in humans and wildlife as well as their ability to bioaccumulate through the food chain, their high resistance to environmental degradation, and their long-range atmospheric transport potential. The monitoring of these compounds in the environment at ultra-trace concentration levels requires highly selective and sensitive analytical methodologies. The lack of reference step-by-step methods led to a high number of reliable determinations depending on analytes, the complexity of the sample, and available instrumentation. Thus, this review article is mainly focused on the last advances in the analytical methodologies for the determination of halogenated organic contaminants. Methodologies regarding sample treatment, chromatographic separation, and mass spectrometry analysis have been reviewed to finally highlight the future perspectives for the improvement of the analytical determinations of these compounds and the throughput of environmental control laboratories in this field.

基于质谱分析方法对卤代有机污染物进行环境分析的最新进展

卤化的有机污染物,包括经立法和潜在的持久性有机污染物及其前体,由于对人类和野生生物具有有害影响以及它们在食物链中的生物蓄积能力,对环境退化的高度抵抗力以及对人体的危害,因此成为主要的环境问题。远距离的大气运输潜力。以超痕量浓度监测环境中的这些化合物需要高度选择性和灵敏的分析方法。缺乏参考逐步方法,导致取决于分析物,样品的复杂性和可用仪器的大量可靠的测定。因此,这篇综述文章主要侧重于测定卤代有机污染物的分析方法的最新进展。审查了有关样品处理,色谱分离和质谱分析的方法,以最终突出显示改进这些化合物的分析测定方法和该领域环境控制实验室的通量的未来前景。
