“…Several other power plants also are located within 100 km upwind and downwind from Parsons. Garner et al 16 found that pollutants emitted high into the atmosphere can be dispersed in all directions, so even plants located downwind may be NO X contributors.…”

“…Recognition that sulfur releases from metal smelters and coalpower plants are a major contributor to atmospheric acid deposition is long standing (1). Natural analogues of these anthropogenic emitters are certain volcanoes, which persistently eject sulfur gases, mainly in the form of SO2, at rates of 0.1-100 kg s -1 into the atmosphere (2).…”

Certain volcanoes constitute the world's largest sources of SO 2 , HCl, and HF emissions and contribute significantly to regional acid deposition. However, the impact of volcanic acid emissions to nearby ecosystems remain poorly documented. In this paper, the spatial pattern of acid dry depositions was monitored within 44 km of Masaya Volcano, Nicaragua, with a network of sulfation plates. Measured SO 2 deposition rates were <2-791 mg m -2 day -1 . The plates also collected the dry deposition of HCl at rates of <1-297 mg m -2 day -1 . A similar deposition velocity V d (gas transfer) of 1.6 ( 0.8 cm/s was calculated for SO 2 and HCl above the plate surfaces. Quantities of SO 2 and HCl deposited daily within the area surveyed amounted to 1.5 × 10 8 g and 5.7 × 10 7 g, respectively, which correspond to about 10% of the total SO 2 and HCl released by the volcano. These depositions may generate an equivalent hydrogen flux ranging from <1 to 30 mg m -2 day -1 . Our results demonstrate that volcano emissions can dramatically affect acid deposition downwind and in turn cause extreme acid loading of the local ecosystems. This study opens exciting prospects for investigating the sensivity of volcanic ash soils to acid inputs.
