Water quality - Guidance standard for the surveying, sampling and laboratory analysis of phytobenthos in shallow running water

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. This 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 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.

Wasserbeschaffenheit - Anleitung zur Beobachtung, Probenahme und Laboranalyse von Phytobenthos in flachen Fließgewässern

Diese Europäische Norm gibt Anleitungen für die Bestandsaufnahme/Probenahme, Identifizierung und grundlegende Quantifizierung des Phytobenthos (außer Makrophyten) in Fließgewässern. Sie ist in Fließ-gewässern anwendbar, in denen benthische Algen und Moose die Hauptprimärproduzenten sind. Dieses Verfahren umfasst alle phytobenthischen Wuchsformen und ermöglicht das Monitoring von Umwelt¬ereig-nissen über ein oder mehrere Jahre. In dieser Hinsicht bietet sie eine Alternative/Ergänzung zu Verfahren, die auf benthischen Diatomeen (EN 13946; EN 14407) und Makrophyten (EN 14184) basieren. Erhobene Daten zu den phytobenthischen Wuchsformen eignen sich für Einzeluntersuchungen, Bewertungen der Wasser¬qualität und für das Trendmonitoring. Diese Europäische Norm umfasst alle Aspekte von der Planung und Gestaltung der Bestandsaufnahmen und Probenahmeprogramme bis zur Bestimmung und grundlegenden Quantifizierung des Phytobenthos.

Qualité de l'eau - Guide pour l'étude, l'échantillonnage et l'analyse en laboratoire du phytobenthos dans les cours d'eau peu profonds

La présente Norme européenne donne des lignes directrices pour l’étude/l’échantillonnage, l’identification et la quantification de base du phytobenthos (autre que les macrophytes) dans les cours d’eau. Elle est applicable aux rivières dans lesquelles les algues benthiques et les bryophytes sont les principaux phototrophes. Cette méthode englobe toutes les formes de croissance phytobenthique et permet de surveiller les réponses biologiques à des événements environnementaux sur une ou plusieurs années. A cet égard, elle fournit une solution alternative aux méthodes basées sur les diatomées benthiques (EN 13946 ; EN 14407) et sur les macrophytes (EN 14184). Les données obtenues pour les formes de croissance du phytobenthos sont adaptées aux études pilotes, à l’évaluation de la qualité de l’eau et au suivi dans le temps. La présente Norme européenne englobe tous les aspects, de la conception des programmes d’étude et d’échantillonnage jusqu’à l’identification et la quantification de base du phytobenthos.

Kakovost vode - Smerni standard za rutinsko pregledovanje, vzorčenje in laboratorijske analize fitobentov v plitvih vodotokih

Ta evropski standard zagotavlja smernice za rutinsko pregledovanje/vzorčenje, prepoznavanje in osnovno količinsko opredelitev fitobentosa (razen  makrofitov) v tekočih vodah. Velja za reke, v katerih so glavni fototrofi bentoške alge in briofiti. Ta metoda obsega vse oblike fitobentoške rasti in omogoča eno- ali večletno spremljanje bioloških odzivov na okoljske dogodke. V tem smislu zagotavlja alternativo metodam na osnovi bentoških diatomej (EN 13946; EN 14407) in makrofitov (EN 14184). Podatki o oblikah fitobentoških rasti so primerni za pilotno rutinsko pregledovanje, ocenjevanje kakovosti vode in spremljanje trenda. Ta evropski standard obsega vse vidike, od zasnove rutinskega pregledovanja in programov vzorčenja do prepoznavanja in osnovnega količinskega določanja fitobentosa.
