环境基质有机标准样品研究进展

Research progress on environmental matrix organic reference materials

有机污染物在环境中广泛存在,其在环境中的浓度和行为受到环境监测与研究人员的高度关注.然而,由于环境基质复杂,有机污染物浓度水平低,环境基质中有机污染物的分析检测十分复杂.环境基质有机标准样品能够对环境有机污染物分析检测过程进行质量控制与质量保证,是保证环境监测和科学研究数据可靠性的计量工具.本文系统综述了国内外土壤、沉积物、大气颗粒物和水基质有机标准样品的研究现状,并介绍了大气颗粒物和水基质有机标准样品的制备技术.根据目前环境监测与科学研究的需求,提出了未来环境基质有机标准样品的研究方向.

Organic pollutants exist widely in environment,and their occurence and behaviors have attracted great attention from environmental monitoring agencies and researchers. The complexity of environmental matrix and very low concentrations of organic pollutants lead to the complex analysis processes of organic pollutants. Environmental matrix organic reference materials（ RMs）, as metrology tools to ensure the data reliability of environmental monitoring and scientific research,can provide quality control and quality assurance for analysis processes. In this review,we systematically summarized the research progress of soil,sediment,air particulate material and water organic RMs,and introduced preparation technologies focusing on air particulate material and water organic RMs.Based on the current requirements,further research directions on environmental matrix organic RMs were also proposed.
