Soil quality. Effects of pollutants on juvenile land snails (Helicidae). Determination of the effects on growth by soil contamination Ingestion-build-224916 The first five mechanisms do1 Scope This document specifies a semi static method for determining the effects of contaminants on growth and survival of young snails, usually Helix aspersaaspersa Mller. 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, mixtures or preparations; soils (contaminated or of unknown
