2018年嘉峪关市大气降水的化学特征及其成因分析

Analysis on the Chemical Characteristics and Causes of Atmospheric Precipitation in Jiayuguan City in 2018

降水是快速去除大气中颗粒物和污染气体的有效方式。通过对2018年嘉峪关市降水pH值、电导率、离子的浓度水平和季节变化研究,笔者确定城市大气污染的成因,旨在为防治大气污染提供科学的控制措施。

Precipitation is an effective way to quickly remove particulate matter and pollutants from the atmosphere. Through the research on the pH value, conductivity, ion concentration level and seasonal variation of precipitation in Jiayuguan City in 2018, the author determined the cause of urban air pollution, in order to provide scientific control measures for the prevention and control of air pollution.
