Understanding the Leaching Process
Leaching is a critical process in soil science, involving the movement of soluble substances through soil. This standard provides a detailed methodology for simulating this process, allowing for the assessment of potential contaminant release. By using a liquid to solid ratio of 2 l/kg dry matter, the standard ensures that the leaching test accurately reflects real-world conditions, providing valuable insights into soil behavior and contaminant mobility.
Importance of Leaching Tests
Leaching tests are vital for understanding the environmental impact of soil contaminants. They help determine the potential for pollutants to migrate from soil into groundwater or surface water, posing risks to ecosystems and human health. By following the BS EN ISO 21268-1:2019 standard, professionals can conduct these tests with confidence, knowing that their methods are scientifically sound and internationally recognized.

BS EN ISO 21268-1:2019
This standard BS EN ISO 21268-1:2019 Soil quality. Leaching procedures for subsequent chemical and ecotoxicological testing of soil and soil-like materials is classified in these ICS categories:
- 13.080.05 Examination of soils in general
This document specifies a test providing information on leaching of soil and soil-like materials under the experimental conditions specified hereafter, and particularly at a liquid to solid ratio of 2Â l/kg dry matter.
The document has been developed to measure the release of inorganic and organic substances from soil and soil-like material as well as to produce eluates for subsequent ecotoxicological testing. For ecotoxicological testing, see ISO 15799[ 6] and ISO 17616[ 7].
Volatile organic substances include the low-molecular-weight substances in mixtures such as mineral oil.
It is not always possible to optimise test conditions simultaneously for inorganic and organic substances and optimum test conditions can also vary between different groups of organic substances. Test requirements for organic substances are generally more stringent than those for inorganic substances. The test conditions suitable for measuring the release of organic substances will generally also be applicable to inorganic substances.
Within the category of organic substances, a significant difference in behaviour exists between the more polar, relatively water-soluble compounds and apolar, hydrophobic organic substances (HOCs). In the latter case, mechanisms of release (e.g. particle-bound or dissolved organic carbon-bound) can be more crucial as well as sorption losses of soluble HOCs on different materials with which they come in contact (e.g. bottles, filters). The test and the results should be used for leaching of organic substances only with thorough consideration of the specific properties of the substances in question and the associated potential problems.
For ecotoxicological testing, eluates representing the release of both inorganic and organic substances are needed. In this document, ecotoxicological testing is also meant to include genotoxicological testing.
This test method produces eluates, which can subsequently be characterized by physical, chemical and ecotoxicological methods in accordance with existing standard methods. The test is not suitable for substances that are volatile under ambient conditions.
This procedure is not applicable to materials with a dry-matter-content ratio lower than 33Â %.
This test is mainly aimed at being used for routine and control purposes, and it cannot be used alone to describe all leaching properties of a soil. Additional leaching tests are needed for that extended goal. This document does not address issues related to health and safety. It only determines the leaching properties as outlined in Clause 4.
