Part of the project is the realisation of a risk assessment system for new chemicals. Currently this system has the form of the computer program DRANC (Dutch Risk Assessment system for New Chemicals). This program is available for advisory tasks concerning the assessment of hazard and risk of new chemical substances (level 0, 1-100 ton/year). This manual describes the use of the program DRANC (version 1.1), which was developed using Turbo Pascal and can be run on all MS-DOS computers.26 pen1292-2risk assessmentrisk analysisevaluation systemwater quality; emissionsproductiondispersionconcentrations in the environmentReport2012-12-12
