<p>ISO 15952:2005 specifies a semi-static method for the determination of the effects of contaminants on growth and survival of young snails, usually <i>Helix aspersa</i> <i>aspersa</i> Müller. The animals are exposed via the cutaneous and digestive route using a test substrate (artificial or natural soil according to the objective of the study) to which defined amounts of the following are added: substances or preparations; and soils (contaminated or of unknown quality) or waste materials. A static method is also described.</p>
<p>ISO 15952:2005 does not apply to volatile substances, i.e. substances for which the Henry constant, H, or the air/water partition coefficient is over 1, or for which the vapour pressure is over 0,013 3 Pa at 25 °C.</p>
<p>This test takes into account possible changes in the test substance, preparation, soil or waste material because the test mixture is prepared and renewed every 7 days during the 28-day test period.</p>
