Impact of COVID-19 on Black Carbon and Carbon Monoxide Levels and Its Health Risk Assessment Over East India
The present research aims to describe the measurement of the changes in air pollutants such as black carbon (BC), PM2.5, and CO concentrations levels, and estimation of their source apportionment and health risk during normal period (NP) as well as lockdown period (LP) in Jamshedpur city. The urban atmospheric pollutants mostly BC, PM2.5 and CO concentrations were observed gradual fall during LP. The averaged mass concentration of BC, PM2.5 and CO was found about 38.46 ± 1.91 µgm−3, 176.55 ± 21.72 µgm−3, 840 ± 282 ppbv in NP and 9.68 ± 2.36 µgm−3, 42.86 ± 18.97 µgm−3, 175.88 ± 121.82 ppbv during LP, respectively. BC, PM2.5, and CO concentrations were shown to be lower during LP as compared to NP. This may be because of prohibited of all human activities due to COVID-19 pandemic. The source apportionment analysis of BC indicated that the biomass burning (62.5%) contribution was high as compared to fossil fuel emission (37.5%) at LP. The air trajectory model showed that most of the air masses were coming from western part of India and also some fresh marine air masses were received at the located position. The health risk for respective health effects of CVM (cardiovascular mortality), LC (lung cancer), LBW (low birth weight), and PLEDSC (percentage lung function decrement of school-aged children) due to exposure to BC was evaluated as 9.76, 4.8, 8.59 and 19.59 PSC in NP and 8.35, 4.1, 7.35 and 16.77 PSC in LP.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
