SPEED-document chloorkoolwaterstoffen

Abstract

This document is a product of the SPEED project (Source reduction cooperation Project aimed at Effective Emission reduction from Diffuse sources). An inventory has been drawn up for the emissions to air and surfacewaters in the Netherlands of seven chlorinated hydrocarbons: dichloromethane, chloroform, carbontetrachloride, 1,1-trichloroethane, 1,2-dichloroethane, tri-chloroethylene and tetrachloroethylene, for which abatement measures are presented. Using the STRAVERA model, future trends in emissions and surface water loading have been computed for three scenarios: (1) established policy, (2) planned policy and (3) additional measures. Because of the fast proceeding of the established and planned policy regarding the chlorinated hydrocarbons scenario (1) and (2) are presented together. The results of the calculations are compared with the government policy target (North Sea Action Plan). Although this target of 50% reduction in surface water loading in 1995 can be achieved for all seven chlorinated hydrocarbons, extra attention must be paid to the development of the emissions of chloroform, dichloroethane, and tetrachloroethylene. This study shows, in fact, that this extra attention is certainly necessary because replacement occurs of one chlorinated hydrocarbon by the other. In "action tabels", an indications is given of which abatement measures should be taken by which organization, in order to result in a decrease of the emissions of the chlorinated hydrocarbons.
