DIN EN 15972:2011-11 EN 15972:2011 (E) 5 Introduction Investigations of phytoplankton are an important part of
35、 marine environment monitoring. Phytoplankton responds rapidly to environmental changes (supply of nutrient salts, climate, light access etc.), and monitoring of occurrence, species composition and biomass may therefore in many cases be used to characterise the environment and the degree of impacts.
36、 The European Union Water Framework Directive therefore requires monitoring of marine phytoplankton as a part of assessments of ecological conditions. Investigations of phytoplankton are also included in monitoring programmes connected with other European directives (Urban Waste Water Treatment Dire
37、ctive, Habitats Directive), international conventions and national regulations. Monitoring of harmful/toxic phytoplankton is carried out both for the aquaculture industry and in connection with authorities control of organisms for human consumption (shellfish). This requires uniform procedures for c
38、ollection and quantification of phytoplankton. Most principles for characterisation of environmental conditions based on phytoplankton require the use of quantitative methods, i.e. that the occurrence of species and quantities can be related to a known water mass. Data interpretation further require
39、s information on the physical and chemical properties of the water body (supporting parameters). In order for environmental authorities to utilise the information, it is important that the investigations are comparable in space and time and that the data is of high scientific quality. This European
40、Standard focuses on a limited selection of methods that can be documented precisely, reproduced and which have been in use for some time. This European Standard does not comprise chlorophyll determination. For chlorophyll determination see ISO 10260 1. WARNING Persons using this European Standard sh
41、ould be familiar with normal laboratory and fieldwork practice. This European Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the users to establish appropriate safety and health practices and to ensure compliance with any
42、 national regulatory conditions. 1 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 epifluorescen
43、ce. 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 for quantification; qualitative analysis. This European Standard describes minimum requirements for environment
