【摘要】 "十五"期间重庆市区雾水呈酸性,近郊区雾水呈弱酸性,远郊区基本未酸化;由市区向外,雾水的电导率逐步降低,阴离子浓度逐步降低,钙离子、铵根离子和钾离子浓度也逐步降低,但钠离子和镁离子则有所不同;重庆雾水的酸化类型以硫酸型为主,其次是盐酸型和硝酸型.雾水的碱化类型在市区和远郊区以钙—铵型为主,在近郊区以钙型为主.雾水中离子浓度比雨水高出数倍.更多还原

【Abstract】 This paper reports pollution and chemical characteristics of fogwater in Chongqing in the period of the 10th five-year plan.Fogwater was acidic in the urban area,weakly acidic in the outskirts and neutral in the suburbs.In space,fogwater conductivity,anion concentrations and NH+4,Ca2+ and K+ dropped steadily from the urban area,to the outskirts and to the suburbs.The distribution of Na+ and Mg2+ showed a different pattern.The primary type of fogwater acidification was H2SO4,and the secondary type was HCl and HNO3.The basification types of fogwater were primarily Ca2+ and NH+4 in the urban zone and suburbs,and Ca2+ in the outskirts.Ion concentration in the fogwater was several times higher than that in the rainwater.更多还原
