UNE-EN ISO 11267:2023

This International Standard specifies one of the methods for evaluating the habitat function of soilsand determining effects of soil contaminants and substances on the reproduction of Folsomia candidaWillem by dermal and alimentary uptake. This chronic test is applicable to soils and soil materialsof 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 substrate.For contaminated soils, the effects are determined in the soil to be tested and in a control soil. Accordingto the objective of the study, the control and dilution substrate (dilution series of contaminated soil) areeither 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 substancesunder temperate conditions.The method is not applicable to volatile substances, i.e. substances for which H (Henry's constant) or theair/water partition coefficient is greater than 1, or for which the vapour pressure exceeds 0.013 3 Pa at25 °C.NOTE The stability of the test substance cannot be ensured over the test period. No provision is made in thetest method for monitoring the persistence of the substance under test.
