| 摘 要： | 分时段对每次降雨连续采样,对pH值、电导率、硫酸根离子、硝酸根离子、氯离子、铵、氟离子、钾离子、钠离子、钙离子、锾离子等共11项进行监测.分析了各种离子的组成、所占比例、时段变化规律和对部分离子的来源进行了探讨.分析结果表明.山形的降雨为硝酸型酸雨,有别于我国大多教城市的硫酸型酸雨类型. |

| Abstract: | Samples were continually collected in separate time period for each precipitation,11 components were measured,which were pH,EC,SO_4~(2-),NO_3~-,Cl~-,NH_4~+,F~-,K~+,Na~+,Ca~(2+) and Mg~(2+).The study is focus on each iron component,ratio,character with time period change and the source of some chemicals.The result shows that the precipitation in Yamagata is nitrate acid rain,which is different from sulphate acid rain in most cities in China. |
