Abstract

This report concludes a series of reports which have to contribute to the technical-scientific basis of parts of part II of the Dutch Soil Protection Guidelines. The results of this study will be used in the periodical revision of this Guidelines. In this study the criterion "serious threat of (human) health or the environment" has a central position. In this report the results of the former published reports (nos. 725201001 to 725201006 and 725201008 are integrated. Relevant information derived from the formed reports is presented. This leads to a Further Investigation procedure in which the determination of the potential and acutal exposure and the risk assessment for man and environment are positioned. Moreover proposals are presented for adjusted and clarified, toxicologically based Dutch C-values. Finally methodological uncertainties are presented and a number of recommendations are made.
