Characteristics and Sources of Chemical Composition of Atmospheric Precipitation in Tianjin

  • 摘要: 为了解天津市大气降水的化学组成及其来源,2013年1—12月在天津市环境监测中心、天津市塘沽区环境保护监测站、天津市蓟县环境保护监测站采集降水样品,分析了pH、EC(电导率)和主要离子的分布特征. 结果表明:天津市降水的pH、EC雨量加权平均值分别为5.58、98 μS/cm. 降水中各离子雨量加权平均当量浓度(当量浓度=质量浓度×离子价数/分子量)为Ca2+>SO42->NH4+>NO3->Cl->Mg2+>Na+>F->K+. 其中,Ca2+、SO42-、NH4+、NO3-和Cl-是降水中的主要离子,占总离子当量浓度的91.3%. 降水中SO42-/NO3-(当量浓度比)为2.1,近10年来呈逐渐降低趋势,表明天津市大气污染向复合型转变趋势明显. 总离子当量浓度季节差异大,冬季高、夏季低;SO42-、NH4+、NO3-等当量浓度在冬季最高,Ca2+当量浓度在春冬季基本相当. 从空间分布上看,降水化学组成在天津市环境监测中心、天津市塘沽区环境保护监测站、天津市蓟县环境保护监测站分别表现为受综合源、工业源和海洋源、工业源和农业源的影响特征. 富集因子计算结果表明:降水中Ca2+和K+主要来自地壳;Mg2+主要来自地壳,同时也受海洋源的影响;Cl-的海洋源和人为源的贡献基本相当;但降水中的SO42-、NO3-主要来自人为活动.
