30、tice. Long periods of analysis at the microscope can cause physical fatigue and affect eyesight. Attention should be given to the ergonomics of the microscope and advice from a health and safety practitioner should be sought to ensure that risks are minimized. The use of chemical products mentioned

31、in this standard can be hazardous and users should follow guidelines provided by the manufacturers and take necessary specialist advice. This standard does not purport to address the safety problems associated with its use. It is the responsibility of the user to establish appropriate health and saf

32、ety practices and to ensure compliance with any national regulatory conditions. The phytobenthos is an important component of aquatic ecosystems and an understanding of the composition of the phytobenthos present in a waterbody can provide useful information on the status of that waterbody, and on a

33、ppropriate management strategies. The Water Framework Directive (2000/60/EC) 3 requires monitoring of the phytobenthos as a quality element used for ecological status assessment, and phytobenthos assessments have also been used in monitoring programmes associated with other European Directives (e.g.

34、 Urban Wastewater Treatment Directive, Habitats Directive) and with national legislation (e.g. NORM M6231). This guidance standard specifically relates to the sampling of phytobenthos (other than aquatic macrophytes) in running water. An etymologically-correct application of the term “phytobenthos”

35、would cover all phototrophic organisms; however, this encompasses a vast range of organisms, from microscopic unicells to macrophytes 2 m in length. As separate survey methods for aquatic macrophytes are available (EN 14184), this document focuses on phototrophic algae and oxygenic cyanobacteria tha

36、t live on substrata. Bryophytes are common in shallow running waters and competitive interactions between these and larger algae are common. Similarly, aquatic macrophyte species may, themselves, act as substrata or competitors for algae and cyanobacteria. For these reasons, the standard provides op

37、tions for including these taxa in survey and sampling procedures. The term “periphyton” is sometimes used instead of “phytobenthos”; however, some definitions of “periphyton” include heterotrophic organisms that live attached to substrata (protozoa, sponges, hydroides). Methods described here deal o

38、nly with photosynthetic organisms but they could, if required, be adapated to encompass heterotrophic organisms too. Methods using phytobenthos to assess water quality in running water have been developed in several European countries 6, 8, 9, 10 and in the USA 2. Recent work is summarised in the pr

39、oceedings of four symposia 1, 7, 11, 12. Methods for the sampling and analysis of one group of phytobenthos, the diatoms, have already been the subject of harmonisation (EN 13946, EN 14407). However, these standards are concerned with only a single group of the phytobenthos and there are situations

40、where other phototrophs are more obvious and can contribute additional ecological information. According to the precise usage to which this standard is to be put it is essential for specifiers and users to mutually agree on any necessary variations or optional procedural details prior to use.

41、 15708:2010-03 EN 15708:2009 (E) 5 1 Scope This European Standard provides guidelines for the survey/sampling, identification and basic quantification of phytobenthos (other than macrophytes) in running waters. It is applicable to rivers where benthic algae and bryophytes are the main phototrophs. T

42、his method encompasses all phytobenthic growth forms and enables biological responses to environmental events over one or more years to be monitored. In this respect it provides an alternative to methods based on benthic diatoms (EN 13946; EN 14407) and macrophytes (EN 14184). Data obtained for the

43、phytobenthos growth forms are suitable for pilot surveys, water quality assessment and trend monitoring. This European Standard encompasses all aspects from the design of survey and sampling programmes to the identification and basic quantification of the phytobenthos. 2 Normative references The fol
