This International Standard specifies one of the methods for assessing the habitat function of soil and determining the effects of soil contaminants and substances on the reproduction of Folsomia candida Willem through skin and dietary intake. This chronic test is applicable to soil and soil materials of unknown nature, e.g. B. contaminated sites, impacted soil, post-remediation soil, industrial, agricultural or other affected sites and waste materials. The effects of the substances are evaluated using a standard soil, preferably a specified artificial soil substrate. In the case of contaminated soil, 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 the substrate used for dilution (dilution series of the 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 moderate conditions. The method is not applicable to volatile substances, ie substances for which H (Henry constant) or the air/water partition coefficient is greater than 1, or for which the vapor pressure at 25 °C exceeds 0.013 3 Pa. NOTE It cannot be guaranteed that the test substance will remain stable throughout the duration of the experiment. The persistence of the test substance is not monitored in the test procedure.
