33、ay a major role in the aquatic food web. They are high-order consumers (often final consumers) and have important functions of regulation in aquatic ecosystems. They are a confirmed part within test concepts regarding aquatic organisms from different trophic levels. The eggs of the zebrafish (Danio

34、rerio Hamilton-Buchanan) are used as test material. The zebrafish belongs to the family of Cyprinidae (carp-related fish) within the class of Osteichthyes (teleost fish). Zebrafish are easy to keep and produce transparent, nonadhesive eggs (diameter about 1 mm) throughout the whole year. Their embry

35、onic development is well described. The zebrafish is one of the most important model fish in research on the developmental biology of vertebrates and is recommended as a test fish, i.e. in the OECD Guidelines 203, 204 and 210. The development of fertilized fish eggs can be affected by water constitu

36、ents and effluents. Death of embryos and certain defined disturbances of embryonic development, which finally lead to death, are considered effects. EN ISO 15088:2008 (E) 4DIN EN ISO 15088:2009-06 WARNING Persons using this International Standard shall be familiar with normal laboratory practice. Th

37、is International Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. IMPORTANT It is absolutely es

38、sential that tests conducted according to this International Standard be carried out by suitably qualified staff. When applying this International Standard, it is necessary in each case to determine if and to what extent additional conditions should be established. 1 Scope This International Standar

39、d specifies a method for the determination of degrees of dilution or of concentrations as a measure of the acute toxic effect of waste water to fish eggs within 48 h. This International Standard is also applicable to treated municipal waste water and industrial effluents. NOTE This International Sta

40、ndard has been elaborated as a substitute for the acute fish toxicity test. Applied to waste water, it gives the same or similar results as achieved from the acute fish toxicity test (e.g. ISO 7346-1 or ISO 7346-2). If used for single substances, different sensitivities from both test systems are po

41、ssible. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

45、me of 1 000 ml (volume fraction of 25 %) represents dilution level D = 4. NOTE See ISO 5667-16. 3.3 EC50concentration at which there is an effect on 50 % of the organisms in line with the test criterion NOTE In this International Standard, LC50is the lethal concentration at which 50 % of the organis

46、ms are dead. 3.4 fish egg generally used term for all development stages of an egg cell (inside the chorion) within this International Standard NOTE If necessary, the following qualifiers for this term are used: “not fertilized”, immediately after spawning; “freshly fertilized”, between 4-cell stage

47、 and 128-cell stage; “embryo”, if the developing embryo is visible inside the egg before hatching. 3.5 lowest ineffective dilution dilution factor LID lowest ineffective dilution tested, expressed as dilution level D (3.2), at which no inhibition, or only effects not exceeding the test-specific vari

48、ability, are observed 3.6 LIDegglowest ineffective dilution within a test batch in which at least 90 % of the fish eggs do not show any effect according to this International Standard NOTE See Clauses 11 and 12 and Figure 2. 3.7 test batch defined dilutions with fertilized fish eggs 4 Interferences

49、The differentiation of eggs can be difficult in the case of heavily coloured and/or turbid waste water. In such cases, the following modified preparation order is used before starting the exposure: spawning; differentiation into fertilized and unfertilized eggs (8.2.2); transfer into dilution water (7.10, crystallization bowls); transfer into microplates without previous exposure. While transferring into microplates, the error in dilution caused by adherent water should be kept as small as possible
