在欧盟委员会标准、测量和测试计划的框架内，通过实验室间的研究，协调了测定淡水沉积物中可提取磷含量的分析方案。在此基础上，研制了一种均匀稳定的沉积物标准物质，并在此基础上进行了验证，并将于2001年春季上市。SMT议定书和参考材料是水管理领域的有用工具，特别是在质量保证和数据可比性对实验室分析至关重要的时候。了解磷的生物可利用形式不仅对沉积物，而且对污泥和土壤都很重要。因此，SMT议定书可以扩展到这些材料，并可以编制新的标准物质。SMT协议被用于一个水库的研究，该协议允许计算P储量，从而有助于预测湖泊的恢复延迟。文中介绍了该协议和客户关系管理，并简要介绍了案例研究。
An analytical protocol for the determination of the extractable phosphorus contents in freshwater sediments has been harmonized through interlaboratory studies in the frame of the Standards Measurements and Testing program of the European Commission. A homogeneous and stable sediment reference material has been prepared and certified on the basis of this protocol named SMT protocol, and will be available in spring of 2001. The SMT protocol, together with the reference material, are useful tools in the field of water management, especially at a time when quality assurance and data comparability are of paramount importance in laboratory analysis. The knowledge of the bioavailable forms of phosphorus is important not only for sediments but also for sludge and soils. Therefore, the SMT protocol could be extended to these materials and new CRMs could be prepared. The SMT protocol was used in a study of a reservoir, which allowed to calculate the P stock, therefore helping to predict the restoration delay of the lake. The paper describes the protocol and the CRM, and gives a brief outline of the case study.
