【摘要】 为彻底了解衡阳市降雨酸化现状,在衡阳市区设置3个监测点,2001～2005年间对市区内每月选取1～2个样品测定pH、电导率、降水量、SO42-、NO3-、F-、C1-、NH4+、Ca2+、Mg2+、Na+、K+等指标.结果表明:衡阳市酸雨呈现冬季>春季>秋季>夏季迹象,为典型的硫酸型酸雨.分析表明市区内酸雨频次有上升的可能,并提出了防治措施。更多还原

【Abstract】 In order to understand the actuality of acid rain pollution in Hengyang City,Hunan Province,three monitoring spots were established and one to two samples each month in 2001～2005 were selected to measure parameters including pH, conductivity,rainfall,SO42-,NO3-,F-,Cl-,NH4+,Ca2+,Mg2+,Na+ and K+.Results showed that the evidence of acid rain was in the rank of winter,spring,autumn and summer,with typical vitriol acid rain.Frequency of acid rain would raise in urban area,and prevention and control measures were also proposed.更多还原
