Emissions of aerial pollutants from poultry houses

For a better understanding of the present emissions of aerial pollutants from livestock production an extensive research project was started. The objective of this project was to provide emission figures that can be used to establish emission factors for aerial pollutants. Within this paper results from dust and ammonia emissions from broilers, layers floor housing, layers aviary housing, broiler breeders, and turkeys are reported. From the results it was concluded that the necessity of this study is shown by the high differences between measured PM10 emissions in this study and the emission factors estimated by conversion from total dust emissions in a previous study. Results show that PM2.5 contribution to PM10 is generally low (5 to 8%), except for turkeys where it was 47%.
