During recent years, the awareness of quality assurance and quality control in environmental analyses has constantly increased, especially due to the implementation of new guidelines and regulations at both the national and international level. Achieving comparable results by using certified reference materials is one of the primary concerns of the scientific community. As a result, there is a growing demand for certified reference materials to cover different matrices and pollutants. Moreover, these CRMs should be in close relationship to the determinants and target concentrations required by environmental bodies and European Directives as well. Supplementary information to this paper presents an inventory of reference materials available on the market from different suppliers against the priority pollutants listed in the Water Framework Directive. These CRMs cover matrices such as water, sediment and biota. The use of CRMs in relationship to appropriate analytical methods and relevant determinants is discussed and the need for matrix-CRMs, particularly for organic pollutants is emphasised. The use of proficiency testing schemes as an alternative for the lack of appropriate CRMs and future trends in the production of CRMs within the BCR framework are also discussed.
近年来，环境分析中对质量保证和质量控制的认识不断提高，特别是由于国家和国际层面实施了新的指导方针和法规。使用经认证的参考物质获得可比结果是科学界的主要关注点之一。因此，对涵盖不同基质和污染物的经认证参考物质的需求日益增长。此外，这些有证参考物质应与环境机构和欧盟指令要求的决定因素及目标浓度密切相关。本文的补充信息列出了市场上不同供应商提供的针对《水框架指令》中列出的优先污染物的参考物质清单。这些有证参考物质涵盖水、沉积物和生物群等基质。讨论了有证参考物质与适当分析方法及相关决定因素的关系，并强调了对基质有证参考物质的需求，特别是对于有机污染物。还讨论了使用能力验证计划作为缺乏适当有证参考物质的替代方法以及在欧盟标准物质与测量局框架内有证参考物质生产的未来趋势。
