29、ional and international levels. Currently available tests use soil-fauna organisms restricted to annelid (earthworms and Enchytraeidae) and arthropod phyla (insects: Collembola and Coleoptera). Among the latter, two standards assess acute toxicity earthworms (ISO 11268-1) and coleoptera larvae6and t

30、hree other standards address sublethal effects of soil contaminants on reproduction (earthworms3, Collembola2, Enchytraeidae4). In the biological cycles of organisms, it appears that growth is, like reproduction, a fundamental ecophysiological parameter to be taken into consideration for the sustain

31、ability of species and ecosystems38.Snails are relevant ecological indicators for assessing the quality of soils(See References 1618 to 20323340 to 42), as they are characteristic of the soil surface layer (saprophagous and phytophagous) of which a large part of the biological cycle takes place in t

32、he soil (egg-laying, hatching, initial stages of development, hibernation, etc.)71829. During the other phases of their cycle, they eat soil and are in contact with the soil via their moist pedal sole (foot) covered with mucus and participate in the permanent exchanges with the soil (water, mineral

33、salts, excrement and finally shell and organic matter when they die)71831. In addition, they constitute an important link between plants, fauna and soil microorganisms. They correspond fully to the criteria for a good biological indicator: easy to sample and identify, they are widely distributed; th

34、ey accumulate contaminants (See References9,11 to 15,171822242930,33 to 48); their ecological and physiological characteristics are well-known71032; and they are now easy to breed under controlled conditions222632. Their susceptibility to common contaminants of their environment has been demonstrate

35、d (See References 11 to 16,19 to 28,30,33 to 38,37 to 48).This International Standard describes a method for determining the effects on survival and growth of young snails of substances, preparations (i.e. a mixture or solution composed of two or more substances), soils or waste materials added to a

36、n artificial or a natural soil. The described method is thus applicable to test contaminated soils or to compare different uncontaminated soils. The recommended species is Helix aspersa aspersa Mller (also commonly called: common garden snail, brown garden snail, garden snail, land snail, “Petit-Gri

37、s”; synonyms: Cantareus aspersus, Cornu aspersum56). Among land snails (stylommatophoran pulmonate gastropod molluscs of the Helicidae family), Helix aspersa aspersa Mller is the most ubiquitous. This palearctic species can be acclimated to regions with different types of climate: Mediterranean, oce

38、anic temperate, midcontinental temperate and even tropical. Helix aspersa aspersa Mller is of European origin and has been introduced into all parts of the world. They are now on all continents except Antarctica10.Indeed, in their natural environment, snails integrate the contaminants by contact (wi

39、th various substrates such as soil, soil leachates, plant litter), by ingestion (of plants and soil), as well as through the respiratory tract729. So, for specific testing purposes (evaluation of pesticide toxicity, for example), another test design, which is focussed on exposure via food uptake, is

40、 optionally available (Annex F and Reference 6).

41、semi-static method for determining the effects of contaminants on growth and survival of young snails, usually Helix aspersa aspersa 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 whi

43、enewed every week during the 28-day test period.A static method may be implemented in addition to the semi-static method (optional). This method is described in Annex A.This method does not apply to substances for which the air/soil partition coefficient is greater than one, or to substances with va
