Abstract
In order to accurately grasp the pollution characteristics,changing trends,influencing factors of non-methane total hydrocarbon pollution in the urban area of Mianyang City and provide technical support for air pollution prevention and control,the study selected non-methane total hydrocarbons,conventional 6 parameters and particulate carbon components automatic monitoring data from January to December of 2021 for comprehensive analysis.The results showed that the overall performance of non-methane total hydrocarbons in the urban area of Mianyang City in 2021 was high in winter and spring and low in summer and autumn,the main sources were motor vehicle exhaust and industrial pollution sources.The concentration of non-methane total hydrocarbons was significant positively correlated with NO2,CO,PM2.5,PM10,OC and EC,and was negative correlated with O3.The concentration of non-methane total hydrocarbons showed a significant negative correlation with air temperature and wind speed and a significant positive correlation with air pressure.Non-methane total hydrocarbons were greatly affected by east and southeast winds.The research results provide scientific support for the formulation of air pollution prevention and control policies in Mianyang City.关键词
