Variation characteristics and source analysis of atmospheric particles in dry continental climate city:Take Turpan City as an example
Takings Turpan,a typical dry city with continental climate in Xinjiang as an example,based on the monitoring date of sulfur dioxide(SO2),nitrogen dioxide(NO2),inhalable particulate matter(PM10),carbon monoxide(CO),ozone(O3)and fine particulate matter(PM2.5)from 2015 to 2017,to analyze the characteristics of atmospheric en-vironmental quality change.The results show that:particulate matter is the primary pollutant in Turpan City and even Xinjiang,PM2.5 is the primary pollutant with the highest frequency in the heating period,PM10 is the primary pollutant with the highest frequency in the dust season,O3 is the primary pollutant with the highest frequency in summer.After deducting dust,PM2.5/PM10 in Turpan City continued to be in a high range,which could not completely eliminate the in-fluence of dust days on the average annual PM2.5 concentration.To improve the air environment quality in Turpan City,must make joint efforts to solve the three major problems of coal burning,industrial pollution and traffic pollution.
