Cross-media environmental control in selected areas Hirnsdorf

For the first time, the environmental situation was examined across media at the site of an intensive livestock farm. The air emissions of particulate matter (PM10), ammonia (NH3), methane (CH4) and nitrous oxide (N2O) were estimated, and waste was collected. Other priorities were the description of the status of groundwater and surface waters and the assessment of local and supra-regional transport emissions. An agricultural assessment has been carried out and nearby protected areas have been described. An expert from the Styrian state government carried out an air quality and odour modelling. The air quality measurements carried out by the Federal Environment Agency do not show any direct influence of the company’s emissions on the local PM10 and NOx pollution, but the operation proves to be a relatively striking source of NH3.
