TY - CHAP ID - 873323 AU - Hofman, Jakub - Hovorková, Ivana - Machát, Jiří PY - 2009 TI - Comparison and characterisation of OECD artificial soils VL - <I>Neuveden</I> PB - Springer CY - Berlin, Germany SN - 9780387889580 KW - artificial soil KW - cadmium KW - soil organic matter KW - phenanthrene KW - sorption KW - standardized tests N2 - OECD artificial soil is widely used substrate in soil toxicity tests. Despite its apparent necessity as a defined mixture relevant for solid phase exposure, several problematic issues have been revealed recently which must be seriously considered. It is not clear, if the OECD artificial soil is really a standardized reference material omitting the influences of varying natural soil properties or if there is still significant variability present which may influence toxicity results. Under the auspices of the EU ringtest for the ecotoxicity of wastes, a new project has been started with the aim to address the variability of nearly 20 artificial soils. Although the collected soils were declared to be prepared strictly according to OECD guideline, they were different even at the first look and the organic carbon content in the artificial soils varied from 1.4 to 6.0%. This indicates variability in organic carbon content of peat from different sources, producers and countries. The cadmium sorption experiment on selected soils suggests that the cadmium Kd varies among artificial soils over one order of magnitude. It is apparent from our pilot results, that there are differences between the OECD artificial soils from various labs in EU. ER -
