摘要
目的 分析克拉玛依市大气颗粒物(PM2.5、PM10)污染分布特征及其对人群的暴露风险.方法 获取2018年1月—2022年12月克拉玛依市大气PM2.5、PM10及空气质量指数资料,采用描述性分析和环境暴露风险评估模型,分别对该市大气污染物浓度特征及人群暴露风险进行研究.结果 2018-2022年克拉玛依市大气PM2.5、PM10浓度值在逐月、季节、年际变化中的差异均有统计学意义(P＜0.01),浓度值分别在1、2、11、12月和冬季较高;空气质量为优良的天数所占比例逐年增加.克拉玛依市2018-2022年PM2.5、PM10暴露风险值均低于最大可接受水平(1×10-6).结论 克拉玛依市大气质量状况明显改善,但在冬季仍需加强大气防治.
Abstract
Objective To understand the distribution characteristics of particulate pollution in the atmosphere and people exposure risk in Karamay,Xinjiang.Methods PM2.5,PM10 and air quality index data of Karamayfrom January 2018 to December 2022 were collected.The mathematical statistics method and environmental exposure risk assessment model were used to study the characteristic distribution of particulate matter pollution and the people exposure risk.Results From 2018 to 2022,there were significant differences in the concentrations of particulate pollutants among the months,seasons and years,which were higher in January,February,November,December and winter,respectively,the ratio of fine days increased year by year.During 2018-2022,the risk of exposure to PM2.5 and PM10 was below the maximum acceptable level(1× 10-6).Conclusion The air quality in Karamay is getting better year by year,but the prevention and control of the atmosphere should be strengthened in winter.
