摘要/Abstract

摘要： 目的综合探讨可吸入颗粒物（inhalable particle,PM₁₀）、细颗粒物（fine particle,PM_2.5）、NO₂、SO、CO和O₃的时空变化特征,旨在为“乌昌石”地区大气污染物防控提供科学依据。方法利用2016—2020年“乌昌石”地区国控站点监测数据,对该地区6种大气污染物的时空分布特征和相关性进行分析。结果 2016—2020年“乌昌石”地区6种污染物浓度空间分布具有明显差异性,除了SO₂和O₃外,其他污染物5年平均浓度最大值均出现在乌鲁木齐市。2016—2020年“乌昌石”地区PM₁₀、PM_2.5、NO₂、CO和SO₂年均值整体呈下降趋势,降幅分别为13.3%、9.3%、17.9%、25.9%和45.2%;O₃年均值整体呈增加趋势,增幅为23.8%。PM₁₀、PM_2.5、NO₂、CO和SO₂浓度的季节变化呈现“冬高夏低”的特征,而O₃浓度在春、夏季高,冬季最低。PM₁₀、PM_2.5、CO和NO₂浓度日变化呈现“双峰”的特征,PM₁₀和PM_2.5浓度夜间波峰均出现在00：00~02：00,而白天波峰分别出现在10：00~13：00和14：00~16：00;NO₂和CO浓度波峰出现在23：00~01：00和09：00~11：00;SO₂和O₃浓度最大值分别出现在13：00~16：00和16：00~17：00。“乌昌石”地区PM₁₀、PM_2.5、NO₂、SO₂和CO浓度之间均呈显著正相关,与O₃浓度呈显著负相关。结论除O₃外,“乌昌石”地区其他大气污染物浓度整体有向好趋势,但PM₁₀和PM_2.5浓度仍未达到国家二级标准,今后“乌昌石”地区应重点关注O₃和大气颗粒物污染协同防治。

Abstract: Objective To systematically analyze the spatial and temporal variation characteristics of inhalable particle（PM₁₀）,fine particle（PM_2.5）,NO₂,SO₂,CO and O₃,provide scientific basis for the prevention and control of air pollutants in "Wuchangshi" area. Methods Based on data from national air quality monitoring sites in "Wuchangshi" area from 2016 to 2020,the spatial and temporal variation characteristics and correlation of six air pollutants were analyzed. Results As for spatial distribution patterns,obviously differences existed for six pollutants in "Wuchangshi" area from 2016 to 2020. Except SO₂ and O₃,the mean concentration of all pollutants was the highest in Urumqi. From 2016 to 2020,the annual mean concentrations of PM₁₀,PM_2.5,NO₂,CO and SO₂ decreased by 13.3%,9.3%,17.9%,25.9% and 45.2%,respectively. In contrast,the annual mean concentration of O₃ increased by 23.8%. The concentrations of PM₁₀,PM_2.5,NO₂,CO and SO₂ were more serious in winter,and the lowest in summer. The highest concentration of O₃ occurred in spring and summer,and the lowest in winter. The daily concentrations of PM₁₀,PM_2.5,CO and NO₂ presented double peaks distribution,the peak of PM₁₀ and PM_2.5 concentration occurred at 00：00-02：00 at night,while the daytime peaks occurred at 10：00-13：00 and 14：00-16：00,respectively. The peak of NO₂ and CO concentration occurred at 23：00-01：00 and 09：00-11：00,respectively. The peak of SO₂ and O₃ concentration occurred at 13：00-16：00 and 16：00-17：00,respectively. The concentrations of PM₁₀,PM_2.5,NO₂,SO₂ and CO in "Wuchangshi" area were significantly positively correlated with each other,while O₃ and the five pollutants were significantly negatively correlated. Conclusion Except O₃,the air pollution in "Wuchangshi" area has been improving year by year,but the pollution of PM₁₀ and PM_2.5 still exceeds the second-level concentration limit,so the emphasis should be placed on the coordinated prevention and control of O₃ and atmospheric particulate pollution in "Wuchangshi" area.
