Analysis of the Chemical Characteristics of Atmospheric Precipitation in Luzhou District from 2013 to 2022

为了解潞州区大气降水的化学特征,本文基于2013—2022年潞州区大气降水监测资料,研究分析了当地近10年大气降水量以及各离子的浓度变化情况。结果表明,5—9月为大气降水的主要时段;潞州区大气降水p H值、电导率比较稳定,无酸雨;主要离子的比例从大到小顺序依次为:SO_(4)^(2-)、NH_(4)^(+)、Ca^(2+)、NO_(3)^(-)、Mg^(2+)、Na^(+)、Cl^(-)、F^(-)、K^(+)、NO_(2)^(-);潞州区大气环境质量较好。

In order to understand the chemical characteristics of atmospheric precipitation in Luzhou District,based on the atmospheric precipitation monitoring data from 2013 to 2022,this paper analyzes the changes in precipitation amount and the concentrations of various ions over the past decade.The results indicate that the main period for atmospheric precipitation is from May to September.The pH value and conductivity of atmospheric precipitation in Luzhou District are relatively stable,with no acid rain observed.The order of concentrations of major ions from highest to lowest is as follows:SO_(4)^(2-)、NH_(4)^(+)、Ca^(2+)、NO_(3)^(-)、Mg^(2+)、Na^(+)、Cl^(-)、F^(-)、K^(+)、NO_(2)^(-).Overall,the atmospheric environmental quality in Luzhou District is good.
