DIN EN ISO 11268-1:2015-11 EN ISO 11268-1:2015 (E) 3 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 176163
33、4). 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 potentially re
34、aching 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 chronic t
35、est for reproduction are available.This part 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
36、chemicals added to a standard soil (e.g. artificial 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
37、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 other species
38、 have not been proven to be more sensitive 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 Unio
39、n 9.DIN EN ISO 11268-1:2015-11 EN ISO 11268-1:2015 (E) 4 WARNING Contaminated soils may contain unknown mixtures of toxic, mutagenic, or otherwise harmful chemicals or infectious microorganisms. Occupational health risks may arise from dust or evaporated chemicals during handling and incubation. Pre
40、cautions 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 contaminants and chemicals to Eisenia fetida/Eisenia andrei by dermal and alimentary uptake. It is applica
41、ble 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 substances are assessed using a standard soil, preferably a defined artificial soil substrate. For contamina
42、ted 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 soil) should be either an uncontaminated soil comparable to the soil sample to be tested (reference s
43、oil) 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 to volatile substances, i.e. substances for which H (Henrys constant) or the air/water partition co
44、efficient 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 test.2 Normative referencesThe following referenced documents are indispensable for the application of
