一次酸性大暴雨分析
A CASE STUDY OF AN ACID RAINSTORM
-
摘要: 酸雨是当代世界上面临的主要环境问题,并已成为人们普遍关注的公害之一.近年来,我国各地区对大气污染和降水化学成分的分析表明,我国南方地区酸雨出现的频率大大高于北方地区.由于城市工业区排出的二氧化硫、氮氧化物等污染物,不只污染城市空气,而且可随着气流输送到很远的距离.加之污染物可以作为凝结核,在云滴、雨滴形成的时候,就可能具有酸的因素.Abstract: In this paper,we analysed an acid rainstorm on August 10-11,1984 in Changchun,and its time-space change of pH and electric conductivity,and the relation between the pH and the meteorological factors and amount of drop size.We also analysed chemical composition of precipitation.
