摘要
本文研究青岛市酸雨污染的状况及其发展趋势。研究结果表明,近年来青岛市酸雨污染相当严重,并有逐年加重的趋势。近年来,青岛市降水酸度 pH 峰值的平均值为3.48,降水酸度 pH 的平均值为4.47,酸雨的频率大于63%。研究还表明,SO_4^(2-)和 NO_3^-是降水的主要污染物,其浓度平均值为194μeq/l;而SO_4^(2-)是降水的最主要的污染物,平均浓度为181μeq/l。青岛市酸雨污染属于硫酸型污染。预测表明,未来青岛市酸雨污染的水平呈缓慢增加的趋势。
This report researches the present situation and the trend of acid rain in Qingdao.It is shown by study that in recent year acid rain pollution of Qingdao was very serious and the trend of the acid rain pollution will be serious year by year next year.In recent year the mean value of precipitation acidity pH peak value was 3.48,the mean value of precipitation acidity pH 4.47,the frequency of acid rain of Qingdao more than 63%.It is shown by study all that SO_4^(2-)and NO_3^- are main pollutants of the precipitation and the mean value of its concentration was 194μeq/l,but SO_4^(2-) most main pollutant of the precipitation and its mean concentration 181μeq/l.Acid rain pollution of Qingdao belongs pollution of Sulfuric acid tapy.It is shown by the prediction that acid rain pollution trend of Qingdao will be in- crease slowly for the future
