Characteristics of Heavy Metal Pollution in Air Particulate Matter in Industrial and Urban Areas of a Certain City
This article monitors the atmospheric environment of an industrial zone and urban area in a certain city in 2023,analyzes the concentration distribution of ambient air particulate matter and the pollution characteristics of heavy metals in ambient air particulate matter,and uses the enrichment factor method to explore the sources of heavy metals.The results show that the concentration of ambient air particulate matter in a certain city shows a seasonal variation pattern,with particulate matter pollution in spring and winter being higher than in summer and autumn,And the concentration of particulate matter in the air of industrial areas is higher than that in urban areas.The concentration of heavy metals in the ambient air particulate matter shows a certain spatiotemporal distribution.The concentration of heavy metals in industrial areas is generally higher than that in urban areas,and arsenic pollution is more prominent.The heavy metal elements cadmium,lead,and arsenic have shown serious enrichment,indicating that human caused heavy metal pollution is extremely serious.Therefore,it is necessary to reduce the emission of heavy metals caused by human factors in actual production and life processes.
