In compliance with the Water Framework Directive (Directive 2000/60/EC ), the diatoms are sampled as sub-element of the aquatic flora. Diatoms are particularly sensitive to saproby, trophy , acidification and salinity and allow to determine the water quality. The methodology are the standards EN 13946 "Water quality Guidance standard for the routine sampling and pre-treatment of benthic diatoms from rivers and lakes. (revised version to be published 2014) and EN 14407 "Water quality Guidance standard for the identification, enumeration and interpretation of benthic diatom samples from rivers and lakes" (revised version to be published 2014).
