A tentative model to calculate the emission amounts of particulates from livestock buildings.

Particles emitted from livestock buildings are supposed to cause health imp lications in nearby residents. This increasingly causes conflicts between f armers and neighbours. At the same time the national emission control regul ations are tightened and focus also on the environmental impact of particul ated emissions. In front of this background a calculation model is presente d by which the emitted masses of PM10 and PM2.5 from animal houses can be e stimated. The model may help to establish emission inventories for particul ates in rural areas with livestock production and can become a valuable ins trument of the emission control act. The validity of the proposed model dep ends largely on the quality and amount of the input data. The more valid da ta are available the more precise the model can work. Therefore it will be necessary to improve the data sets on emission amounts for PM10 and PM2.5. Inspite of these limitations it appears that a first and reliable estimatio n of particulate emission amounts from animal buildings can be given by the proposed model calculation.
