Evaluation and revision of the CSOIL parameter set.Proposed parameter set for human exposure modelling and deriving Intervention Values for the first series ofcompounds

摘要

Intervention Values are generic soil quality standards used to classifyhistorically contaminated soils, sediments and groundwater (i.e. before1987) as seriously contaminated in the framework of the Dutch SoilProtection Act. In 1994 Intervention Values were published for 70(groups of) compounds. Intervention values are based on potential risksfor both human health and ecosystems. Human toxicological Serious RiskConcentrations for soil, sediment and groundwater (SRChuman) aredetermined using the human exposure model CSOIL. This report presents anevaluation and revision of the CSOIL parameter set as part of thetechnical evaluation of the Intervention Values. The evaluation of theCSOIL parameter set comprises the physicochemical data of all compoundsfor the first series, as well as the soil, site and exposure parameters. The evaluation results in a revised CSOIL data set with an improvedunderpinning and traceability of the data set. Another improvementconcerns the revision of the soil-water partition coefficients. Thereport also provides insight into the impact of the revised data set onthe SRChuman and resulted in a better insight into the uncertainties andvariation of the model input parameters.
