Abstract
The Swedish Environmental Research Institute investigated the concentrations and total loads of reduced nitrogen compounds (ammonia and NH{sub 4}) around Ryssberget hill during the summer of 1992. This area has a high background load of nitrogen due to long range transported pollutants, as well as to local sources of ammonia, mainly extensive pig and mink farming in the Listerlandet region. The purpose of the study was to: provide detailed information on locally raised levels of ammonia in the air; and to measure the extent to which the local emissions of ammonia to the air are responsible for nitrogen loads deposited to forests in the vicinity of Ryssberget hill. The investigation consists of measurements of air concentrations of ammonia in agricultural areas and in forest stands, combined with deposition measurements of nitrogen and other compounds in a beech forest. Measurements were made during a warm summer period from June through August 1992. The decreasing values of ammonia between the coast and Ryssberget hill on the west side indicate that the main source of ammonia are to the south of the investigated region. The 1992 results indicate a local emission contribution of 0.5-1.5 kg NH{sub 4}-N/ha to the total deposition of nitrogen

The local sources of nitrogen that were studied adds significantly to the total nitrogen load on Ryssberget during the summer period. During winter the emissions from local sources are most likely low, but the high total deposition of long-range nitrogen can jeopardize the health of the Ryssberget forest and induce nitrogen leakage to the aquatic environment. 5 refs, 3 figs, 6 tabs}
