EN ISO 18772:2014 (E) DIN EN ISO 18772:2014-07 3 Introduction Current soil and soil-materials management (risk assessment practices or regulations) is often based only on the total amount of contaminants in soil. However, total composition is inadequate for the assessment of several
28、 types of impacts such as impacts on soil, groundwater and surface water due to leaching and subsequent transport of contaminants (inorganic, organic and natural radionuclides) with water. Indeed, for many constituents, a significant fraction of the total content is essentially non-leachable, that i
29、s to say non-removable when it comes into contact with a liquid. Thus, a key aspect to assess the possible management solutions for soil and soil materials in relation to the presence of contaminant is the release-to-the-water phase. This can be addressed with leaching tests which can be used to cha
30、racterise the source term when performing impact assessment and also for the determination of a leached amount of contaminants when checking compliance with respect to existing limits or for comparison purposes (e.g. quality control, treatment efficiency). These statements are relevant for natural,
31、contaminated and agricultural soils and also for soil materials. Leaching tests, particularly those developed for soil and soil materials, are suitable for the following applications: a) Application of leaching tests to determine the leaching behaviour in the framework of impact assessment Generally
32、, impact assessment is based on the source/pathway/receptor framework. Source: assess the release, identify speciation of constituents and retention mechanisms. Receptor: determine the potential targets. Pathway: estimate the transfer of the source towards the target (e.g. underground water, surface
33、 water, plants, soil organisms, ecosystems). In this process, leaching tests are used to characterise the source term (so-called characterisation tests) in accordance with a given scenario (e.g. contamination of the groundwater due to a contaminated site or a soil amended with sludges), which can ei
34、ther be generic or site-specific. Leaching tests may also be used as a tool to assess bioavailability (see ISO 17402). b) Application of leaching tests for compliance and comparison Based on the background information on the soil and soil materials sampled (e.g. origin, nature of constituents and co
35、ntaminants, existing documented information, leaching behaviour), relatively simple and quick leaching tests can be performed for compliance and comparison purposes. In contrast to characterisation tests, this type of test is not designed to provide information on leaching mechanisms and controlling
36、 factors. However, it should be possible to link the information obtained with compliance tests to the more elaborate characterisation tests. EN ISO 18772:2014 (E) DIN EN ISO 18772:2014-07 4 1 Scope This International Standard provides guidance on the appropriate use of leaching tests on soil and so
37、il materials, in order to determine the leaching behaviour in the framework of impact assessment, or for compliance and comparison purposes, including information on the following: the choice of leaching tests, depending on the nature of the problem to be solved and the specific features of the diff
38、erent tests; the interpretation of the test results; the limitations of the tests. In this respect, it is important to keep in mind that leaching tests do not aim to simulate real field conditions, but are designed to address the contact between a solid and a liquid phase for different purposes that
39、 are described in this International Standard. This International Standard only concerns natural, contaminated and agricultural soils and soil materials. Questions relating to the leaching of wastes are not covered by this International Standard. It also does not cover the subject of bioavailability
40、 of contaminants to living organisms, which is covered by ISO 17402. Leaching tests are designed and used for characterisation of the source term. It may be possible to address transport aspects with leaching tests if some basic requirements are known (e.g. hydrodynamic), thus allowing the determina
41、tion of key transport parameters (e.g. retardation factors, particle-facilitated transport, attenuation processes). In this International Standard, when the term “soil” is only quoted to simplify the writing, the broader term “soil and soil materials” shall be considered. 2 Normative references The
