Persons using this European Standard should be familiar with normal laboratory pra
18、ctice. 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
19、 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 sa
20、fety 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
21、appropriate 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
22、. 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”
23、 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 th
24、at 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 o
