Water quality - Determination of the acute lethal toxicity of substances to a freshwater fish (Brachydanio rerio Hamilton-Buchanan (Teleostei, Cyprinidae)) - Part 2: Semi-static method (ISO 7346-2:1996)

Specifies a semi-static method for the determination of the acute lethal toxicity of stable, non-volatile, single substances, soluble in water under specified conditions, to a freshwater fish (Brachydanio rerio - zebra fish). Replaces the first edition.

Wasserbeschaffenheit - Bestimmung der akuten letalen Toxizität von Substanzen gegenüber einem Süßwasserfisch (Brachydanio rerio Hamilton-Buchanan (Teleostei, Cyprinidae) - Teil 2: Semistatisches Verfahren (ISO 7346-2:1996)

Dieser Teil der ISO 7346 legt ein semistatisches Verfahren zur Bestimmung der akuten letalen Konzentration von stabilen, nicht-flüchtigen, unter gegebenen Bedingungen wasserlöslichen Einzelsubstanzen gegenüber einem Süßwasserfisch (Brachydanio rerio Hamilton-Buchanan (Teleostei, Cyprinidae)- Trivialname Zebrabärbling) in Wasser einer festgelegten Beschaffenheit fest. Das Verfahren ist anwendbar auf die Ermittlung einer großen Bandbreite akuter letaler Toxizität der zu untersuchenden Substanz gegenüber Brachydanio rerio unter den Testbedingungen.

Qualité de l'eau - Détermination de la toxicité aiguë létale de substances vis-à-vis d'un poisson d'eau douce (Brachydanio rerio Hamilton-Buchanan (Téléostei, Cyprinidae)( - Partie 2: Méthode semi-statique (ISO 7346-2:1996)

La présente partie de l'ISO 7346 prescrit une méthode semi-statique pour la détermination de la toxicité aiguë létale de substances simples, stables, non volatiles, solubles dans l'eau dans les conditions prescrites, vis-à-vis d'un poisson d'eau douce [Brachydanio rerio Hamilton-Buchanan (Téléostei, Cyprinidae) -- nom commun, poisson-zèbre], dans une eau de qualité donnée. La méthode est applicable pour chaque substance à expérimenter, pour donner une idée globale de la toxicité aiguë létale vis-à-vis du Brachydanio rerio, dans les conditions de l'essai. Les résultats sont en eux-mêmes insuffisants pour définir des normes de qualité de l'eau en vue de la protection de l'environnement. La méthode est également applicable à certaines autres espèces de poissons d'eau douce comme organismes pour essai1). La méthode peut être adaptée pour d'autres poissons d'eaux douce, marine ou saumâtre avec des modifications appropriées des conditions d'essai, concernant notamment la quantité et la qualité de l'eau de dilution et la température.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each 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. IS0
collaborates closely with the International Electrotechnical Commission
(I 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 IS0 7346-2 was prepared by Technical Committee
ISO/TC 147, Water quality, Subcommittee SC 5, Biological methods.

Introduction
The three parts of IS0 7346 describe methods of determining the acute
lethal toxicity of substances to the zebra fish (Brachydanio rerio
Hamilton-Buchanan) but it must be emphasized that the recommended
use of the zebra fish does not preclude the use of other species. The
methodologies presented here may also be used for other species of
freshwater, marine or brackish water fish, with appropriate modifications
of, for example, dilution water quality and the temperature conditions of
the test.
Within the three parts of IS0 7346, a choice can be made between static,
semi-static and flow-through methods” The static test, described in
IS0 7346-1, in which the solution is not renewed, has the advantage of
requiring simple apparatus, although the substances in th
