氮氧化物在闽南地区酸雨中的贡献

Contribution of NO x to Acid Rain in Minnan Area

通过对闽南地区降水、雾水和空气质量等数据的分析，说明闽南地区酸雨是燃煤和光化学烟雾混合型污染；闽南地区降水的ＳＯ２－４／ＮＯ－３比值是我国主要酸雨区中最低的，ＮＯｘ是闽南地区酸沉降形成的重要致酸前体物之一；

The data analysis of rainwater, fog water and air quality in Minnan area shows that acid rain in Minnan area is caused by the combined pollution of coal combustion and photochemical smog; the ratio of SO 2- 4 to NO - 3 of rainwater in Minnan area is the lowest among those in main acid areas of China; NO x is one of the most important precursors of acid rain; local source emission is the major source of NO - 3 of acid deposition in Minnan area.
