Analysis of the Main Components and Sources of Atmospheric Particulate Pollutants in Industrial Cities
Taking a specific industrial city as an example,the spatial distribution,temporal distribution,and chemical composition of suspended particulate matter in the atmosphere were analyzed using sample collection and chemical analysis methods.By collecting particulate matter samples in different regions,seasons,and time periods,advanced analytical techniques such as ion chromatography,thermal optical reflectance,inductively coupled plasma mass spectrometry,and gas chromatography-mass spectrometry are used to qualitatively and quantitatively analyze pollutants such as organic carbon,elemental carbon,inorganic ions,heavy metals,and polycyclic aromatic hydrocarbons in particulate matter.The results showed that the concentration of suspended particulate matter in industrial areas was significantly higher than that in commercial areas,residential areas,and suburbs.In winter and spring,the concentration of suspended particulate matter was much higher than in other seasons.Chemical composition analysis reveals a complex spectrum of pollutants,in which the presence of organic matter,inorganic ions,and heavy metals points to industrial emissions and traffic exhaust as the main sources of pollution.The research findings provide scientific basis for formulating air pollution prevention and control strategies,which is of great significance for improving air quality in industrial cities and protecting residents'health.
