Spredningsberegninger for ammoniakkutslipp. Leangen idrettsanlegg i Trondheim.
NILU has calculated concentrations of ammonia (NH3) caused by emissions at Leangen sport stadium for different emission heights. The outlet for ammonia should be at least 21 m above ground level in order to avoid exceedance of the limit value for working conditions. As long as the emission continues, the hourly average ground level concentrations will be above the odour threshold downwind from the emission.
