Water quality - Sampling in deep waters for macro-invertebrates - Guidance on the use of colonization, qualitative and quantitative samplers (ISO 9391:1993)

The colonization samplers described allow water quality to be assessed by providing a collection of macro-invertebrates indicative of the water quality at the sites of concern. They do not sample the natural invertebrate fauna, which may be restricted by physical conditions unrelated to water quality, and are to be used when studying lowland river waters of depth over 1 m. The deep water samplers described are for use in rivers deeper than 1 m on substrata ranging from mud to stones. They are unsuitable when sampling over macrophytes or stones of sizes greater than about 15 cm, or in very fast flowing water.

Wasserbeschaffenheit - Probenahme von Makro-Invertebraten aus tiefen Gewässern - Anleitung zum Einsatz von qualitativen und quantitativen Sammlern und Besiedlungskörpern (ISO 9391:1993)

Diese internationale Norm ist eine Hilfe zum Gebrauch von Besiedlungskörpern und dem Sammeln von Makro-Invertebraten mit qualitativen und quantitativen Sammlern in tiefen Flüssen. Besiedlungskörper erlauben die Bewertung der Wasserbeschaffenheit, indem sie die Ansiedlung einer Lebensgemeinschaft von Makro-Invertebraten ermöglichen, die für die Wasserbeschaffenheit von Bedeutung ist. Besiedlungskörper sammeln nicht die natürliche Invertebraten- Fauna, die durch die physikalischen Bedingungen, die in keiner Beziehung zur Wasserbeschaffenheit stehen, beschränkt wird.

Qualité de l'eau - Echantillonnage de macro-invertébrés en eaux profondes - Guide d'utilisation des échantillonneurs de colonisation, qualitatifs et quantitatifs (ISO 9391:1993)

La présente Norme internationale donne des directives générales sur l'utilisation des échantillonneurs de colonisation et sur l'échantillonnage des macro-invertébrés à l'aide d'échantillonneurs qualitatifs et quantitatifs pour les rivières profondes. Les échantillonneurs de colonisation permettent d'évaluer la qualité de l'eau en fournissant une collection de macro-invertébrés représentative de la qualité de l'eau sur les sites concernés; les échantillonneurs de colonisation n'échantillonnent pas la faune naturelle d'invertébrés, qui peut être réduite par des conditions physiques sans rapport avec la qualité de l'eau. Ils doivent être utilisés lorsqu'on étudie les eaux de rivières de plaine d'une profondeur supérieure à 1 m. Ils ne sont pas recommandés lorsqu'ils peuvent donner lieu à une accumulation de débris, subir des inondations, être exposés au-dessus du niveau de l'eau, faire l'objet d'actes de vandalisme ou de problèmes d'ancrage. Les échantillonneurs d'eaux profondes doivent être utilisés dans des rivières d'une profondeur supérieure à 1 m et sur des substrats allant de la boue aux pierres. Ils sont inutilisables pour un échantillonnage sur macrophytes ou pierres d'une taille supérieure à environ 15 cm, ou dans des eaux à courant rapide.

Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national Standards bodies (ISO member bodies). The work
of preparing International Standards is normally carried out through ISO
technical committees. Esch member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(1 EC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 9391 was prepared by Technical Committee
ISOnC 147, Water quality, Sub-Committee SC 5, Biological methods.
Annexes A and B form an integral part of this International Standard.

Introduction
A major Problem when using benthic macro-invertebrate communities as
indicators of water quality in rivers is the inherent natura1 differentes in
community structure caused by factors other than water quality, for ex-
ample current velocity and the nature of the substratum. In upland rivers,
riffles provide suitable comparable sampling sites where differentes in
water quality tan be detected biologically. In lowland rivers, suitably lo-
cated riffles may not be available, and in larger deeper rivers riffles may
be totally absent. In addition, methods suitable in shallow waters are not
practicable for deeper, waters where alternative methods have to be used.
Therefore, although desirable for purposes of comparison, it is not poss-
ible to adopt a Standard method of sampling for the benthos of all rivers.
In lowland rivers, riffles are not always available for sampling and therefore
a corresponding Standard benthic biotope for comparison using water
quality is not always available. Although the smaller, slow-flowing lowland
rivers with a depositing substratum and rooted plants support a charac-
teristic rich macro-invertebrate fauna, such biotopes are not always avail-
able in the lower stretches of larger rivers. In such rivers, the benthic
macro-invertebrate fauna may be severely restricted by adverse physi
