Abstract

The purpose of this study is, to find out the sensibility of the Simplebox model for the value of abiotic degradation constants. The 3scale version of Simplebox was used for this sensitivity test. 3scalbox is a spreadsheetmodel, programmed in Microsoft Excel. The basis of this model is the fugacitymodel of Mackay. This multicompartimental and 0-dimential model has been developed at the RIVM to predict the influence of partition properties and degradation data on the persistence of a chemical. Chemical properties taken for this test were the octanol-water partitioncoefficient (Kow), the vapor pressure and the pseudo first order degradation constant of a hypothetical chemical in water.
