摘要 1993年3~4月,在闽南地区进行了一次综合性酸雨集中观测,探讨其雾水特征如下:闽南地区雾水已严重酸化,其最低pH值达到2.91,是该地区酸性湿沉降的重要组成部分;雾水中有机酸根的贡献占总阴离子量9%;雾水含较多四价硫,并与甲醛反应形成络合物;雾水受到周围海洋的影响。 From March to April of 1993, a centralized comprehensive observation of acid rain was carried out in Minnan area and the characteristics of fog water was probed into. The results show that fog water in Minnan area has been acidified, which is an important part of the wet deposition in this area while its lowest pH value reaches as low as 2.91; organic acid radical content in fog water accounts for 9% of total anion amount; fog water in this region contains much S(Ⅳ) which can react with formaldehyde to form complex; surrounding sea affects the fog water characteristics, which makes Cl - much loss in this region.
