British Standards Institution (BSI) has recently published BS EN ISO 11268-2:2023 Soil quality – Effects of pollutants on earthworms – Part 2: Determination of the effects on reproduction of Eisenia fetida/Eisenia andrei and other earthworm species. It is available for purchase from the BSI bookshop.
This document specifies one of the methods for evaluating the habitat function of soils and determining the effects of soil contaminants and chemicals on the reproduction of Eisenia fetida/Eisenia andrei by dermal and alimentary uptake. This chronic test is applicable to soils and soil materials of unknown quality, e.g. from contaminated sites, amended soils, soils after remediation, agricultural or other sites concerned, and waste materials.
This method is designed mainly for determining the effects of soil contaminants and chemicals on the reproduction of Eisenia fetida/Eisenia andrei. Technical information is also provided on how to use Eisenia fetida/andrei for testing chemicals under tropical conditions (see Annex A). Finally, this method also includes technical information on how to use it with other environmentally relevant earthworm species: e.g. Dendrodrilus rubidus and Aporrectodea caliginosa (see Annexes B and C).
This method does not apply to substances for which the air/soil partition coefficient is greater than one, or to substances with vapour pressure exceeding 300 Pa, at 25 °C. This method does not take into account the persistence of the substance during the test.
