Recently implemented have been the thoroughly revised intervention values for soil clean-up. In this report, proposals will be presented for intervention values for 15 additional compounds on the basis of an ecotoxicological and a human-toxicological evaluation. For all compounds the human-toxicological serious soil contamination concentration was calculated using the CSOIL model and the human-toxicological maximum permissible risk levels. The ecotoxicological serious soil contamination concentration was determined by the methodology of Denneman and Van Gestel (1990, 1991), updated by Crommentuijn et al. (1994). Proposals for intervention values are determined by means of integrating the ecotoxicological and the human-toxicological serious soil contamination concentrations. The ecotoxicological serious soil contamination concentrations and the Maximum Permissible Risk levels in this report have been described in detail in report nos. 715810008 and 715810009, respectively. The proposals for the intervention values are derived according to the procedures described for the first and second series of compounds in a number of previous reports. Depending on sensitivity and reliability of the input parameters, various efforts have been made to obtain reliable input parameter values. In this report, intervention values for soil and groundwater are proposed for silver, ethylene glycol, diethylene glycol, acrylonitrile, formaldehyde, methanol, 1-butanol, butylacetate, methyl tert-butyl ether, 1,1-dichloroethane, 1,1,1-trichloroethane, cis- & trans-1,2-dichloroethene and a mixture of aromatic solvents (containing high concentrations of C3 en C4 alkyl benzenes). For dodecylbenzene a risk evaluation is executed but no intervention value is proposed because of lack of an ecotoxicological serious soil contamination concentration and reliable physicochemical data.
