This study selected Bozhou of Xinjiang, the main cotton producing region in northern Xinjiang, as the research object, and collected hourly concentration data of six pollutants from 2017 to 2021, and analyzed the spatial and temporal distribution characteristics of each pollutant. At the same time, Morlet wavelet analysis was used to further analyze the variation period of PM2.5 (PM particles with aerodynamic diameters less than 2.5 \u03bcm) concentration. The Weather Research and Forecasting model coupled with the Community Multiscale Air Quality (WRF-CMAQ) model was used to evaluate the emissions reduction measures for the most polluted month. The results showed that the concentration of particulate matter (PM particles with aerodynamic diameters less than 2.5 \u03bcm and 10 \u03bcm) decreased from the southern mountains to the north; moreover, the concentrations of CO (carbon monoxide), NO2 (nitrogen dioxide), and SO2 (sulfur dioxide) in the suburbs were higher than those in the urban center. The concentration of O3 (Ozone) was the highest in summer, while the concentrations of other pollutants were high in autumn and winter. Under the time scale of a = 13, 24, PM2.5 had significant periodic fluctuation. The health risk values of PM2.5 and PM10 in this study were within the scope of the United States Environmental Protection Agency (USEPA) criteria, but it is still necessary to keep a close watch on them. In the context of emissions reduction measures, agricultural sources reduced by 20%, residential sources by 40%, industrial sources by 20%, and transportation sources by 20%; no change in the power source remains. Under these conditions, the daily average value of each pollutant met the first level of the national ambient air quality standard. The research results provide a reference for the local government to formulate heavy pollution emissions reduction policies.<\/jats:p>","DOI":"10.3390\/ijerph20032273","type":"journal-article","created":{"date-parts":[[2023,1,30]],"date-time":"2023-01-30T03:31:11Z","timestamp":1675049471000},"page":"2273","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Analysis of Pollution Characteristics and Emissions Reduction Measures in the Main Cotton Area of Xinjiang"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9333-4090","authenticated-orcid":false,"given":"Chunsheng","family":"Fang","sequence":"first","affiliation":[{"name":"College of New Energy and Environment, Jilin University, Changchun 130012, China"},{"name":"Key Laboratory of Groundwater Resources and Environment, Ministry of Education, Jilin University, Changchun 130012, China"},{"name":"Jilin Province Key Laboratory of Water Resources and Environment, Jilin University, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhuoqiong","family":"Li","sequence":"additional","affiliation":[{"name":"College of New Energy and Environment, Jilin University, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weihao","family":"Shi","sequence":"additional","affiliation":[{"name":"College of New Energy and Environment, Jilin University, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ju","family":"Wang","sequence":"additional","affiliation":[{"name":"College of New Energy and Environment, Jilin University, Changchun 130012, China"},{"name":"Key Laboratory of Groundwater Resources and Environment, Ministry of Education, Jilin University, Changchun 130012, China"},{"name":"Jilin Province Key Laboratory of Water Resources and Environment, Jilin University, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,27]]},"reference":[{"key":"ref_1","unstructured":"(2022, October 12).
