Analysis of the Characteristics and Changing Trends of Anions and Cations in Atmospheric Particulate Matter in Guizhou Province
The anions and cations in atmospheric particulate matter not only affect air quality,but also human health and ecosystems.Taking Guizhou province as the research area,the atmospheric particulate matter samples are collected and measured,and the characteristics and changing trends of anions and cations are deeply analyzed in atmospheric particulate matter.The research results indicate that the composition of anions and cations in atmospheric particulate matter in Guizhou province is influenced by various factors,among which the increase in human activities significantly changes the source and proportion of anions and cations.The mass ratio of nitrate(NO3-)to sulfate(SO42-)can characterize the contribution of mobile sources to atmospheric particulate matter,and the larger the NO3-/SO42-,the higher the contribution of mobile sources to atmospheric particulate matter.The decrease in ammonium(NH4+)concentration in atmospheric particulate matter reflects the effective control of ammonia source emissions,which is closely related to the renovation of coal-fired small boilers and industrial source pollution control.Deeply exploring the concentration and structural characteristics of anions and cations in atmospheric particulate matter in Guizhou province,and analyzing the trend of changes in anions and cations in atmospheric particulate matter can help to clarify the current status and main influencing factors of regional atmospheric environmental quality,further reveals the complexity and dynamics of atmospheric particulate matter pollution,and provides important basis for formulating effective measures for air pollution prevention and control.
