Chemical Characteristics and Pollution Analysis of Atmospheric Precipitation in Mining District of Yangquan City from 2018 to 2022
In order to know the chemical characteristics and pollution sources of atmospheric precipitation in Mining District of Yangquan City,samples of atmospheric precipitation from 2018 to 2022 were collected,and pH,conductivity,ions composition were measured.The chemical characteristics and pollution situation of precipitation were analyzed.The results show that the pH value of precipitation in Mining District is between 6.34 and 8.80,a weak alkalinity.The electrical conductivity ranges from 23 μS/cm to 289 µS/cm.Ca2+,NH4+,SO42-and NO3-are major inorganic ions.The ratio of SO42-/NO3-ranges from 1.20 to 6.88,with an average of 3.43,indicates that the precipitation type is sulfuric acid.However,over time,the precipitation type is likely to shift towards a compound type.
