近三十年来，美国国家标准与技术研究所（Gaithersburg， MD）一直致力于开发用于测定环境基质中有机污染物的标准参考物质（srm）。这些材料中的有机污染物包括多环芳烃（PAHs）、多氯联苯（PCBs）、氯化农药，以及最近的溴化阻燃剂（多溴联苯醚[PBDEs]）。环境基质包括化石燃料、空气和柴油颗粒物质、室内灰尘、煤焦油、沉积物、贻贝和鱼类组织、鱼油和鲸脂。最近SRM的发展和活动导致了一些环境SRM，这些SRM对于确保环境法医学中分析测量的质量非常有用，在环境法医学中，有机污染物的来源概况通常在一系列环境或生物基质中进行。Particle-related SRM发展包括新房子的问题尘埃物质(SRM 2585有机污染物粉尘),和两个SRM的换发新证:柴油颗粒物材料(SRM 1650 b柴油机颗粒物)认证和引用值97多环芳烃和nitro-PAHs和河流沉积物(SRM 1939 b河流沉积物中多氯联苯)为更多的PCB同类浓度相对于前1998年认证以及多氯联苯。煤焦油SRM （SRM 1597a煤焦油中多环芳烃的复杂混合物）也已重新发布，扩大了多环芳烃的值范围（包括甲基和二甲基取代的多环芳烃，分子质量为302的多环芳烃异构体和多环芳烃硫杂环[PASH]）。最新的生物SRM发展包括新的鱼组织SRM （SRM 1947密歇根湖鱼组织）和鱼肝油（SRM 1588b鱼肝油中的有机物）和人血清（SRM 1589b人血清中的多氯联苯、农药、多溴二苯醚和二恶英/呋喃）的重新认证。SRM 1588b为124个成分分配了值，SRM 1589b为88个成分分配了值。本文概述了最近这些SRM活动，并介绍了新开发的颗粒相关SRM和生物SRM中选定的有机污染物值。讨论了这些材料在环境法医测量中保证质量的作用。
For nearly three decades the National Institute of Standards and Technology (Gaithersburg, MD) has been involved in the development of Standard Reference Materials (SRMs) for the determination of organic contaminants in environmental matrices. Classes of organic contaminants characterized in these materials include polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), chlorinated pesticides, and most recently, brominated flame retardants (polybrominated diphenyl ethers [PBDEs]). Environmental matrices include fossil fuels, air and diesel particulate matter, house dust, coal tar, sediment, mussel and fish tissue, fish oil, and whale blubber. Recent SRM developments and activities have led to a number of environmental SRMs that are useful for assuring quality of analytical measurements in environmental forensics where source profiling of organic contaminants is often conducted in a range of environmental or biological matrices. Particle-related SRM developments include the issue of a new house dust material (SRM 2585 Organic Contaminants in House Dust), and the recertification of two SRMs: a diesel particulate matter material (SRM 1650b Diesel Particulate Matter) for certified and reference values for 97 PAHs and nitro-PAHs and a river sediment (SRM 1939b PCBs in River Sediment A) for a greater number of PCB congener concentrations relative to its former certification in 1998 as well as for total PCBs. A coal tar SRM (SRM 1597a Complex Mixture of PAHs from Coal Tar) has also been reissued with an expanded range of values for PAHs (including methyl- and dimethyl-substituted PAHs, PAH isomers of molecular mass 302, and polycyclic aromatic sulfur heterocycles [PASH]). The latest biological SRM developments include the issue of a new fish tissue SRM (SRM 1947 Lake Michigan Fish Tissue) and the recertification of a cod liver oil (SRM 1588b Organics in Cod Liver Oil) and a human serum (SRM 1589b PCBs, Pesticides, PBDEs, and Dioxins/Furans in Human Serum). SRM 1588b has values assigned for 124 constituents, and SRM 1589b has values assigned for 88 constituents. An overview of these recent SRM activities is provided in this paper, and selected organic contaminant values in newly developed particulate-related and biological SRMs are presented. The usefulness of these materials for assuring quality in environmental forensic measurements is also discussed.
