20、ISO 11268-2:2012(E)ForewordISO (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. Each member body interested in a sub

21、ject 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 (I

22、EC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committe

23、es 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.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be he

24、ld responsible for identifying any or all such patent rights.ISO 11268-2 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 4, Biological methods.This second edition cancels and replaces the first edition (ISO 11268-2:1998), which has been technically revised.ISO 11268 con

25、sists of the following parts, under the general title Soil quality Effects of pollutants on earthworms: Part 1: Determination of acute toxicity to Eisenia fetida/Eisenia andrei Part 2: Determination of effects on reproduction of Eisenia fetida/Eisenia andrei Part 3: Guidance on the determination of

26、effects in field situationsiv ISO 2012 All rights reservedBS EN ISO 11268-2:2015ISO 11268-2:2012(E)IntroductionEcotoxicological test systems are applied to obtain information about the effects of contaminants in soil and are proposed to complement conventional chemical analysis (see ISO 15799 34and

27、ISO 17616 35). ISO 15799 includes a list and short characterization of recommended and standardized test systems and ISO 17616 gives guidance on the choice and evaluation of the bioassays. Aquatic test systems with soil eluate are applied to obtain information about the fraction of contaminants pote

28、ntially reaching the groundwater by the water path (retention function of soils), whereas terrestrial test systems are used to assess the habitat function of soils. As standardized test systems using earthworms as indicator organisms for the habitat function of soil, an acute test for survival and a

29、 chronic test for reproduction are available.This part of ISO 11268 describes a method that is based on the determination of sublethal effects of contaminated soils on adult earthworms of the species Eisenia fetida (Savigny 1826) and Eisenia andrei (Andr 1963). Optionally, the method can be used for

30、 testing chemicals added to standard soils (e.g. artificial soil) for their sublethal hazard potential to earthworms. Finally, information is provided on how to use this method for testing chemicals under tropical conditions (see Annex A).Eisenia fetida and Eisenia andrei are considered to be repres

31、entatives of soil fauna and earthworms in particular. Background information on the ecology of earthworms and their use in ecotoxicological testing is available. Other species, e.g. Aporrectodea caliginosa, Lumbricus rubellus and Lumbricus terrestris, have also been used as test organisms. These or

32、other species have not been proven to be more sensitive in general, and the database and experience in testing soils is small 1617.This part of ISO 11268 has been drawn up taking into consideration test procedures adopted by the Organization for Economic Cooperation and Development 2728and by the Eu

34、 otherwise harmful chemicals or infectious microorganisms. Occupational health risks may arise from dust or evaporated chemicals during handling and incubation. Precautions should be taken to avoid skin contact.1 ScopeThis part of ISO 11268 specifies one of the methods for evaluating the habitat fun

35、ction of soils and determining the effects of soil contaminants and chemicals on the reproduction of Eisenia fetida/Eisenia andrei by dermal and alimentary uptake. This chronic test is applicable to soils and soil materials of unknown quality, e.g. from contaminated sites, amended soils, soils after

36、 remediation, agricultural or other sites concerned, and waste materials.Effects of substances are assessed using a standard soil, preferably a defined artificial soil substrate. For contaminated soils, the effects are determined in the test soil and in a control soil. According to the objective of

37、the study, the control and dilution substrate (dilution series of contaminated soil) should be either an uncontaminated soil comparable to the soil sample to be tested (reference soil) or a standard soil (e.g. artificial soil).Information is provided on how to use this method for testing chemicals u

38、nder temperate as well as under tropical conditions.The method is not applicable to volatile substances, i.e. substances for which H (Henrys constant) or the air/water partition coefficient is greater than 1, or for which the vapour pressure exceeds 0,013 3 Pa at 25 C.This method does not take into

39、account the persistence of the substance during the test.2 Normative referencesThe following referenced documents are indispensable for the application of this document.
