Abstract

Air pollution is one of the most critical environmental challenges and threats to humans. Ozone and nitrogen dioxide (their sum is defined as oxidant, OX) are among the criteria air pollutants and have serious health effects. Oxidant is affected by emission sources in local and regional domains. In this work, a systematic and critical review is conducted on the existing studies of the local and regional oxidant contributions. The systematic review focuses on the publication year, journal rank, study location, and keyphrase analysis. The critical review examines the analyzed parameters, and temporal variations and the data analysis of local and regional contributions of oxidant. The systematic review showed that the studies were conducted in 13 different countries and were published in 19 scientific journals. The critical review indicated that O3, NO, NO2, NOx, and OX were used in all the studies. Furthermore, meteorological parameters of temperature and wind speed were mostly employed in the literature. Due to the substantial effects of emission and meteorological parameters on OX, different time scales were defined so that these effects could be evaluated separately. Our findings revealed that the highest OX’s local and regional contributions belong to daily (24-h average) and daylight time scales, respectively. The statistical analysis of the present study shows that the regional contribution values have less variations than the local contribution ones. This is due to the fact that the regional contribution values are influenced by a larger spatial domain and are less dependent on emission sources of each location.

基于监测数据的地方和区域氧化剂(OX = O3 + NO2)水平贡献分析综述
空气污染是人类面临的最严峻的环境挑战和威胁之一。臭氧和二氧化氮(它们的总和被定义为氧化剂,OX)属于标准空气污染物,对健康有严重影响。氧化剂受本地和区域排放源的影响。在这项工作中,我们对有关本地和区域氧化剂贡献的现有研究进行了系统和严格的审查。系统性综述侧重于发表年份、期刊排名、研究地点和关键词分析。批判性综述审查了氧化剂对当地和区域贡献的分析参数、时间变化和数据分析。系统综述显示,这些研究在 13 个不同的国家进行,发表在 19 种科学杂志上。严格审查表明,所有研究都使用了 O3、NO、NO2、NOx 和 OX。此外,文献中大多采用了温度和风速等气象参数。由于排放和气象参数对 OX 的影响很大,因此界定了不同的时间尺度,以便分别评估这些影响。我们的研究结果表明,OX 对本地和区域的影响最大的时间尺度分别是每天(24 小时平均值)和白天。本研究的统计分析显示,区域贡献值的变化小于本地贡献值。这是因为区域贡献值受更大空间范围的影响,对各地排放源的依赖性较小。

期刊介绍: International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management. A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made. The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
