PAH in surface water: sources and emission reduction measures

PAK in oppervlaktewater: bronnen en maatregelen. SPEED werkplan PAK


This plan of action is a product of SPEED (Source reduction cooperation Project aimed at Effective Emission reduction of Diffuse sources). For two polycyclic aromatic hydrocarbons, i.c. benzo(a)pyrene (BAP) and fluoranthene (FLU) dutch emissions to air and water reduction measures are presented. Using the STRAVERA model the future developments of the emissions and the surface water load are calculated for three situations: autonomous (1), planned policy (2) and extra measures (3). In the first two situations an increase of the surface water load is expected of 30 to 65%, mainly due to the expected increase of shipping. Assuming foreign emissions are reduced with the same percentage as in the Netherlands in 2000, the additional measures in this plan of action will result in reductions of the surface water load of 50% in 2010. In spite of the inaccuracy of the emission data, it can be concluded that these measures fail to reacht the governmental policy targets of 90% reduction. In action table is indicated which organisations should take initiative in reducing PAH emissions. A committee in which several departments are represented will supervise the progress of the emission reduction measures.
