Immission approach

The emission approach should be strengthened, the EU-WFD should not be minimized to an immission approach directive. 

Determination of environmental carcinogens is not an end in itself. Although often misunderstood or misinterpreted, the aim of scientific work in this area is to collect data on human exposure, to pinpoint emission and immission sources and to determine the causes of potential health risks to humans. The ultimate aim is always elimination or reduction of human exposure and thereby prevention of human cancer. In view of the slow progress in the treatment of human cancer this approach is an important strategy in the fight against this disease. 

However, we must keep in mind the limitations of this approach, especially the transfer of consistent sets of dispersion parameters to the propagation of air pollution in the vicinity of a source. The Gaussian plume formula should be used only for those downwind distances for which the empirical diffusion coefficients have been determined by standard diffusion experiments. Because we are interested in emissions near ground level and immissions nearby the source, we use those diffusion parameters which are based on the classification of Klug /12/ and Turner /13/. The parameters are expressible as power functions,...
