Reactive nitrogen (Nr) emissions and nitrogen deposition have increased rapidly and will continue to increase with the increasing fossil fuel combustion and application of N fertilizer since the industrial revolution. Nitrogen deposition has led to a series of negative effects on ecosystems such as soil acidification, water eutrophication, and loss of biodiversity in grasslands and forests. Therefore, atmospheric Nr pollution and deposition induced by excessive anthropogenic Nr have become an environmental concern worldwide. However, little is known about N deposition in Shanxi Province. The temporal variation of atmospheric N deposition was quantified using DELTA system, passive samplers, and particulate samplers at Gu Cheng, Shanxi Province, in a one year study. Results showed total wet N precipitation was up to 12.43 kg N hm^-2 a^-1 in this area, which was far below the average value (28.0 kg N hm^-2 a^-1) in the North China Plain. During wet precipitation, the concentration of NO₃^--N, NH₄⁺-N, and dissolved organic N averaged 1.24 mg N/L, 1.27 mg N/L, and 1.26mg N/L, respectively. In a year, wet precipitation of N showed a distinguished monthly variation due to different monthly rainfall, and 60% of wet deposition occurred from April to October. The major form of dry deposition was NO₃^--N, the rate of which was 1.12 times that of NH₄⁺-N. As a typical dry land, the rate of dry deposition was 3 times that of wet deposition. The total amount of nitrogen deposition was up to 47.86 kg N hm^-2 a^-1. There was a positive line corelation between NO₃^--N and NH₄⁺-N in rainwater, and that was a power corelation in PM₁₀ particulates. However, dissolved C and N showed a positive line corelation in rainwater and a quadratic polynomial corelation in PM₁₀ particulates. All these relationships can provide a way to determine one of them through another. Such high deposition rates of Nr species in the Shuozhou area indicated a serious pollution from anthropogenic sources and significant atmospheric N input to croplands.
