29、al test systems are applied to obtain information about the effects of contaminants in soil and are proposed to complement conventional chemical analysis. ISO 15799 includes a list and short characterization of recommended and standardized test systems. Aquatic test systems with soil eluate are appl

30、ied 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 used to assess the habitat function of soils. For the latter, a standardized test system using Enchytraeidae (a chro

31、nic test with end-point reproduction) is proposed.This International Standard describes a method that is based on the determination of acute and sublethal effects of contaminated soils to adult Enchytraeidae of the genus Enchytraeus. Optionally, the method can be used for testing substances added to

32、 standard soils (e.g. artificial soil) for their sublethal hazard potential to Enchytraeidae.Soil-dwelling annelids of the genus Enchytraeus are ecologically relevant, i.e. they are abundant in many soils where earthworms are scarce, but can also reach high population densities in soils well inhabit

33、ed by earthworms. Enchytraeidae can be used in laboratory tests as well as in semi-field and field studies. From a practical point of view, many Enchytraeus species are easy to handle and breed, and their generation time is significantly shorter than that of earthworms the test duration for a reprod

34、uction test with Enchytraeidae is four weeks to six weeks, compared to eight weeks (12 weeks including synchronization) with earthworms. In addition, a much smaller volume of soil is needed in the enchytraeid test compared to the amount needed in earthworm tests.This International Standard has been

35、drawn up taking into consideration test procedures recommended by the Organization for Economic Cooperation and Development (see22,24).4DIN EN ISO 16387:2014-05 EN ISO 16387:2014 (E) 1 ScopeThis International Standard specifies one of the methods for evaluating the habitat function of soils and dete

36、rmining effects of soil contaminants and substances on the reproduction of Enchytraeus sp. by dermal and alimentary uptake in a chronic test. It is applicable to soils and soil materials of unknown quality, e.g. from contaminated sites, amended soils, soils after remediation, agricultural or other s

37、ites under concern 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 soil to be tested and in a control soil. According to the objective of the study, the control and

38、 dilution substrate (dilution series of contaminated soil) are either an uncontaminated soil comparable to the soil to be tested (reference soil) or a standard soil (e.g. artificial soil).This International Standard provides information on how to use this method for testing substances under temperat

39、e 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.NOTE No provision is made in the test method for monitoring the persis
