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 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 temperate conditions.
The method is not applicable to volatile substances, i.e. substances for which H (Henry’s constant) or the air/water partition coefficient is greater than 1, or for which the vapour pressure exceeds 0,0133 Pa at 25 °C.
NOTE The stability of the test substance cannot be ensured over the test period. No provision is made in the test method for monitoring the persistence of the substance under test.
