English Abstract This report presents the estimates which are used to
calculate the PEC's (Predicted Environmental Concentration) in air and soil
at or near the source for the use categories dealt with in the Dutch Risk
Assessment System for New Chemicals (DRANC) so far, i.e. textile dyes,
photochemicals, metalworking and hydraulic fluids, paperchemicals,
intermediates and "general". The estimates are based on data in available
reports on releases for these categories (see references) and the estimates
made for the Priority Setting System for Existing Chemicals. In those cases
where no data were available an educated guess was made.
