26、ervedBS EN ISO 11268-1:2015ISO 11268-1:2012(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 1579933 and ISO 1761634). ISO 15799 includes a list and short cha

27、racterization 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 potentially reaching the groundwater by the water path (r

28、etention 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 chronic test for reproduction are available.This par

29、t of ISO 11268 describes a method that is based on the determination of the acute toxicity of contaminated soils to adult earthworms of the species Eisenia fetida (Savigny 1826) and Eisenia andrei (Andr 1963). Optionally, the method can be used for testing chemicals added to a standard soil (e.g. ar

30、tificial soil) for their acute toxic 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 representatives of soil fauna and earthworms in particular. Ba

31、ckground 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 other species have not been proven to be more sensitive

32、in general, and the database and experience in testing soils is small 151623.This part of ISO 11268 has been drawn up taking into consideration test procedures adopted by the Organization for Economic Cooperation and Development 2627and by the European Union 9.

33、O 11268-1:2015BS EN ISO 11268-1:2015Soil quality Effects of pollutants on earthworms Part 1: Determination of acute toxicity to Eisenia fetida/Eisenia andreiWARNING Contaminated soils may contain unknown mixtures of toxic, mutagenic, or otherwise harmful chemicals or infectious microorganisms. Occup

34、ational 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 function of soils and determining the acute toxicity of soil contam

35、inants and chemicals to Eisenia fetida/Eisenia andrei by dermal and alimentary uptake. It is applicable to soils and soil materials of unknown quality, e.g. from contaminated sites, amended soils, soils after remediation, agricultural or other sites concerned, and waste materials.Effects of substanc

36、es are assessed using a standard soil, preferably a defined artificial soil substrate. For contaminated soils, the effects on survival are determined in the test soil and in a control soil. According to the objective of the study, the control and dilution substrate (dilution series of contaminated s

37、oil) 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 under temperate as well as under tropical conditions.The method is not applicable

38、 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 account the possible degradation of the substances or contaminants during the te

It is therefore not necessary, before using such a soil in a definitive test, to demonstrate the suitability of the artificial soil in complying with the validity
