摘要

为防止 COVID-19 扩散而实施的严格封锁减少了大城市的空气污染物排放量。利用伊朗大不里士空气质量监测站(AQMS)的数据,采用比较法分析了 COVID-19 封锁对环境空气污染浓度的影响以及气象参数对其的影响。与其他阶段相比,除 O3 外,封锁第一阶段所有污染物的空气质量均有明显改善。封锁(限制社会接触,关闭商店、学校、大学、餐馆以及许多行政中心和公司等)暂时减少了空气污染物。将封锁期间的气象参数与往年同期相比,结果显示差异无统计学意义(P 值为 0.05)。因此,在封锁期间,气象参数对减少空气污染物没有干预作用。封锁对空气污染物浓度的影响可为了解市民遵守检疫的程度、评估其他空气质量政策以及评估减少各种排放源的影响提供一种特殊的方法。

Air Quality Variations and Influence of COVID‑19 Lockdown Restrictions on it in Tabriz, Iran

The severe lockdown imposed to prevent the spread of COVID-19 decreased the emissions of air pollutants in large cities. A comparative approach was adopted to analyze the effect of the COVID-19 lockdown on ambient air pollution concentrations and the impacts of meteorological parameters on them using data from air quality monitoring stations (AQMS) in Tabriz, Iran. Air quality improvement was significant for all pollutants, except for O3, in the first phase of the lockdown compared to other phases. The lockdown (restricted social contact, closing of shops, schools, universities, restaurants, and many administrative centers and companies, etc.) temporarily reduced air pollutants. Comparing meteorological parameters between lockdown periods and the same period in previous years showed no statistically significant variations (P-value < 0.05). Therefore, the meteorological parameters did not intervene in reducing air pollutants during the lockdown. The effects of lockdown on the concentration of air pollutants could provide a special way to understand the extent of quarantine compliance by citizens, evaluate additional air quality policies, and assess the impacts of reducing various emission sources.

期刊介绍: International Journal of Environmental Research is a multidisciplinary journal concerned with all aspects of environment. In pursuit of these, environmentalist disciplines are invited to contribute their knowledge and experience. International Journal of Environmental Research publishes original research papers, research notes and reviews across the broad field of environment. These include but are not limited to environmental science, environmental engineering, environmental management and planning and environmental design, urban and regional landscape design and natural disaster management. Thus high quality research papers or reviews dealing with any aspect of environment are welcomed. Papers may be theoretical, interpretative or experimental.
