Translated Title
Soil pollution and soil ecosystems: proposal for C-values based on ecotoxicological risks
Published in
Abstract
In the Leidraad Bodemsanering a list of C-values is given for levels of chemicals in soil. Exceeding of the C-values will generally lead to (an investigation on the need for) soil decontamination or excavation. In the Leidraad Bodemsanering the practical use of C-values is explained. And the scientific backgrounds with respect to the risks fo both public health and the environment as a consequence of soil pollution are discussed. In this report the ecotoxicological risk for soil organisms of the substances in the Leidraad Bodemsanering is evaluated, leading to a proposal for (new) C-values. In the Leidraad bodemsanering C-values are related to 'serious danger'. In this report the starting point is chosen, that there is a 'serious danger' for a soil ecosystem when the survival of 50% of the species in it is threatened. This will be the case when the NOEC (No-Observed-Adverse-Effect-Concentration) for effects on vital life-functions, like growth and reproduction, is exceeded.<br>
