Water quality. Guidance standard on assessing the hydromorphological features of lakes Ingestion-build-47786 It determines the PTPB concentration1 Scope This European Standard is applicable to lakes, which are water bodies occupying one or more basins with surface areas greater than 1 ha (0,01 km2) and maximum depths (at mean water level) greater than 1 m. All types of permanent lakes, including natural, modified and artificial, freshwater and brackish, except for those systems which regularly connect to the sea, are included in this European Standard, though canals are excluded.
