摘要
在庐山电视台采集的云雾水与同时段、同一地点采集的雨水相比,除Cl^-外各种离子浓度前者明显高些,pH值也较高。云雾水和地面同时段雨水相比较,云雾水中NO^-_3,SO^-_4,NH^+_4,Ca^(++),F^-及Mg^(++)等离子浓度也较高,但云雾水和雨水二者比值较小,云雾水的pH值也较高。云雾水中离子浓度和上风向污染源关系密切,其主要通过气溶胶的输送从而影响云雾水成份。有雨情况下云雾水中的离子浓度随时间推移而逐渐减少。
Ion concentrations without Cl-and pH value in cloud-fog water collected at TV station in Lu Shan mountain were higher than in the rain water collected in same site during similar period. For comparison it with rain water on ground during similar period, the character of NO3-, SO4=, NH4+, Ca++, F- and Mg++ were same to above. But the ratio values of cloud-fog water with rain water for former were higher than for later. The ion concentration of cloud-fog water was closely related to up-wind pollution source. The source influences the constituent of cloud-fog water mainly through transport of aerosol. The ion concentration of cloud-fog water with time gradually decreases in rainning.
