Diatoms are widely used for monitoring rivers in many European countries, where standard methods are applied. The study of specific composition of epilithic diatoms can give useful information on biological quality of rivers. In Italy a method (EPI-D eutrophication pollution index with diatoms) has been developed for Appenine watercourses, based on sensibility of diatoms towards organic pollution, mineralization of water and chloride. Sampling protocols for epilithic diatoms and determination of EPI-D are described, together with application perspectives in Italy.
硅藻在许多欧洲国家被广泛用于河流监测，这些国家采用标准方法。对附着在石头上的硅藻特定组成的研究可以提供有关河流生物质量的有用信息。在意大利，基于硅藻对有机污染、水的矿化作用和氯化物的敏感性，已经为亚平宁山脉的水道开发了一种方法（带硅藻的EPI-D富营养化污染指数）。文中描述了附着在石头上的硅藻的采样方案和EPI-D的测定方法，以及在意大利的应用前景。
