摘要：

Wet and dry (dust) deposition was measured in the Serra dos Orgaos National Park. VWM pH was 5.3. Non-sea-salt (nss) SO42- comprised 97% of total SO42-. The molar ratio [2(nss-SO42-) + NO3-/[NH4+ + H+] was 1. 1, suggesting that pH is predominantly controlled by H2SO4, HNO3, and NH3. Wet deposition of NH4+, NO3-, and nss-SO42- was respectively 0.59, 0.25, and 0.30 kmol ha(-1) yr(-1). Assuming that dry deposition of N can comprise 30-50% of its total (dry + wet) deposition, the latter is estimated to be 1.2-1.7 kmol ha(-1) yr(-1) (17-24 kg N ha(-1) yr(-1)).
