It supersedes BS 7755-4.2

2、.4:1999 (dual numbered as ISO 11267:1999), which is withdrawn. This revised version of ISO 11267:1999 primarily relates to the inclusion of a methodology for the testing of field or “contaminated” soil. In the opinion of the committee, the standard appears to have been prepared without satisfactory

3、validation trials. During the drafting of this revision, the UK committee raised three primary concerns relating to this standard, as follows: Field soils from potentially contaminated sites may be clayey or contain stones, plant roots and other matter. It may be difficult to achieve the 30 g repres

4、entative soil sample using a 4 mm sieve (as stated in subclause 5.2.1 of the standard). Hand sorting and larger mesh sizes may be more practical. Field-collected soils may contain high fungal loading. Under the optimal growth conditions used in the incubation phase of the Collembola test, fungal hyp

5、hae can undergo considerable growth such that they may form a mat covering the surface of the soil. This can prevent movement of the Collembola at the soilair interface, thereby reducing survival and reproduction. It can also hinder successful measurement of the survival and reproduction endpoints.I

6、f the growth of fungal mats occurs, further guidance can be found in the Environment Agencys Standard Operating Procedures for Bioassays, published in the series An ecological risk assessment framework for contaminants in soil (Science report SC070009/SR3). When applying the validation criteria, par

7、ticularly concerning field-collected soil past experience has suggested these performance criteria may be difficult to achieve even during tests conducted in OECD standardised soil. This means that for tests using field soils it is very likely that one of the validation criteria will not be met1.The

8、 UKs ecological risk assessment (ERA) framework for land contamination (Environment Agency, 2008)2, recommends accepting the results of Collembola bioassays used incontaminated land assessment that do not meet all the required criteria. Professional judgement and the experience of the testing labora

9、tory should be used when applying this standard in relation to UK regulations, for example by considering data with results obtained in other Collembola tests undertaken by the laboratory. As experience is gained it may be possible to refine the acceptance criteria.The UK participation in its prepar

35、:2014(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 2 and 4). Reference 2 includes a list and short characterization of recommended and standardized test syste

36、ms and 4 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 (retention function of soils), whereas terrestrial test systems are

37、 used to assess the habitat function of soils.Soil-dwelling Collembola are ecologically relevant species for ecotoxicological testing. Springtails are prey animals for a variety of endogeic and epigeic invertebrates and they contribute to decomposition processes in soils. In acidic soils they may be

38、 the most important soil invertebrates besides enchytraeids with respect to that function, since earthworms are typically absent.19Additionally, Collembola represent arthropod species with a different route and a different rate of exposure compared to earthworms1and enchytraeids.3Various species wer

39、e used in bioassays of which four species were used most commonly, Folsomia candida, Folsomia fimetaria, Onychiurus armatus, and Orchesella cincta.20Numerous soil toxicity tests supported by Environment Canada (EC) resulted in the development and standardization of a biological test method for deter

40、mining the lethal and sublethal toxicity of samples of contaminated soil to Collembola.10The method prepared by EC includes three species, Orthonychiurus folsomi, Folsomia candida, and Folsomia fimetaria. As standardized test systems using Collembola as indicator organisms for the habitat function o

41、f soil, another two methods exist. One is designed for assessing the effects of substances on the reproductive output of the Collembola, Folsomia fimetaria L. and Folsomia candida Willem in soil,19,21, and the other method described here, focuses on testing contaminated soil. Optionally the method c

42、an be used for testing substances added to standard soils (e.g. artificial soil) for their sublethal hazard potential to Collembola.This International Standard describes a method that is based on the determination of sublethal effects of contaminated soils to adult Collembola of the species Folsomia

43、 candida Willem. The species is distributed worldwide. It plays a similar ecological role to Folsomia fimetaria.10,19Folsomia candida reproduces parthenogenetically and is an easily accessible species as it is commercially available and easy to culture. Folsomia candida is considered to be a represe

44、ntative of soil arthropods and Collembola in particular. Background information on the ecology of springtails and their use in ecotoxicological testing is available.22 ISO 2014 All rights reserved vBS EN ISO 11267:2014BS EN ISO 11267:2014Soil quality Inhibition of reproduction of Collembola (Folsomi

45、a candida) by soil contaminants1 ScopeThis International Standard specifies one of the methods for evaluating the habitat function of soils and determining effects of soil contaminants and substances on the reproduction of Folsomia candida Willem by dermal and alimentary uptake. This chronic test is

46、 applicable to soils and soil materials of unknown quality, e.g. from contaminated sites, amended soils, soils after remediation, industrial, agricultural or other sites of concern and waste materials.Effects of substances are assessed using a standard soil, preferably a defined artificial soil subs

47、trate. For contaminated soils, the effects are determined in the soil to be tested and in a control soil. According to the objective of the study, the control and dilution substrate (dilution series of contaminated soil) are either an uncontaminated soil comparable to the soil to be tested (referenc

48、e soil) or a standard soil (e.g. artificial soil).This International Standard provides information on how to use this method for testing substances under temperate conditions.The method is not applicable to volatile substances, i.e. substances for which H (Henrys constant) or the air/water partition

49、 coefficient is greater than 1, or for which the vapour pressure exceeds 0,013 3 Pa at 25 C.NOTE The stability of the test substance cannot be ensured over the test period. No provision is made in the test method for monitoring the persistence of the substance under test.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
