Water quality. Guidance on quantitative and qualitative investigations of marine phytoplankton Ingestion-build-266356 This International Standard specifies a1 Scope This European Standard gives guidance for sampling, preservation, storage, quantification and qualitative analysis of phytoplankton from marine waters. Guidance for quantification is limited to the use of light microscopy with phase contrast and epifluorescence. This European Standard specifies: the development of the sampling programme; requirements for sampling equipment; procedures for sampling and treatment of samples in the field; methods
