Pollution characteristics and health risk of air pollutants in Longkou City,Shandong province in 2023
Objective To understand and master the pollution characteristics and people health risks of air pollutants in Longkou City,and provide the technical support for air pollution control work.Methods Descriptive analysis of the pollution characteristics of air pollutants in Longkou City in 2023,correlation analysis between pollutants,and health risk assessment of each air pollutant.Results The annual average mass concentration of the three monitoring points in Longkou City in 2023 met the national second level standard.The health risk values of SO2,NO2,PM10 and PM2.5 did not exceed the potential risk range specified by EPA.PM10(66.55 μg/m3)and PM2.5(31.83 μg/m3)had the highest quality concentrations at monitoring point C,and their coefficient(rs=0.895)and health risk value(R=1.33×10-6,R=1.27×10-6)were both highest.NO2(23.65 μg/m3)and SO2(10.53 μg/m3)had the highest quality concentrations at monitoring point A,and their coefficient(rs=0.776)and health risk value(R=2.89×10-6,R=1.62×10-6)were also high.Conclusion The air quality in Longkou City meets the related standards,and there are spatial differences in the content of air pollutants.It is recommended to carry out targeted air quality management based on the situation of monitoring points.
