A harmonised procedure for the determination of the forms of phosphorus in freshwater sediments, developed in the frame of the European Programme, Standards, Measurements and Testing (SMT) has been used for a certification campaign for a reference material. This operationally defined scheme is a good compromise between method performance and reproducibility. Furthermore, the method is rather simple to implement and could be used by water managers on a routine basis. A homogeneous and stable sediment reference material has been prepared and will be available before mid 2001. The so-called SMT protocol, together with the reference material, are useful tools in the field of water management, especially at a time when quality assurance is of paramount importance in laboratory analyses. Knowledge of the bioavailable forms of phosphorus is important not only for analysis of sediments but also for sludge and soils. Therefore, the SMT protocol could be extended to these materials.
在欧洲标准、测量与测试计划（SMT）框架下制定的用于测定淡水沉积物中磷形态的统一程序，已用于一种参考物质的认证活动。这种基于操作定义的方案在方法性能和可重复性之间取得了良好的平衡。此外，该方法实施起来相当简单，水管理人员可将其用于日常工作。现已制备出一种均匀且稳定的沉积物参考物质，将于2001年年中之前提供。所谓的SMT方案以及参考物质，是水管理领域的有用工具，尤其是在质量保证对实验室分析至关重要的时期。了解磷的生物可利用形态不仅对沉积物分析很重要，对污泥和土壤分析也很重要。因此，SMT方案可扩展至这些物质。
