Abstract
The final report is presented for the project 'Dry deposition from plumes of coal-fired installations', which formed part of the air pollution research programme. Purpose of this exploratory project was to collect literature data on the dry deposition of important air pollutants emitted by coal-fired power stations, and on measuring methods for dry deposition. Measuring equipment has been built for measuring dry deposition. Preliminary measurements of dry deposition of oxides of nitrogen and of sulfur, and of ozone and aerosol particles have been carried out over grass. Dry deposition is described as transport across consecutive layers. Transport through most of the atmospheric boundary layer can be calculated from meteorological quantities only. Uptake by the surface (e.g. soil, water or vegetation) depends on the nature of the pollutant as well as on the physical, chemical and biological properties of the surface. It is commonly characterized by the surface resistance. Literature data on deposition velocity and surface resistance have been collected for sulfur dioxide, nitrogen oxides and their conversion products, for hydrogen chloride and hydrogen fluoride, and for trace compounds in aerosol form. The deposition velocity of the last-mentioned depends strongly on the particle size distribution of the aerosol. Measurements were carried

Measurements were carried out with the gradient method for nitrogen oxides (NO and NO/sub x/), for ozone (O/sub 3/), and for sulfur dioxide (SO/sub 2/). For NO and NO/sub x/ fluxes towards the surface as well as upward fluxes were measured. Fluxes for ozone and for aerosol particles with diameter larger than 0.5 micrometer were measured with the eddy correlation method. The flux for ozone was generally directed towards the surface. 110 refs.}
