The nationwide lockdown in India to flatten the pandemic COVID-19 curve has resulted reduction of anthropogenic emission sources a great extent. This study reports change air quality and its impact on environment during unique scenario at Bhubaneswar, coastal smart city east India. urban shows remarkable mean pollutant levels influenced by traffic viz. NOx (~ 67 %) BC 47 over pre-lockdown. Comparatively, lower CO 14 is attributed dominance natural atmospheric chemical regulation biogenic...
In this study, we assess the response of ambient aerosol black carbon (BC) mass concentrations and spectral absorption properties across Indian mainland during nation-wide lockdown (LD) in connection with Coronavirus Disease 19 (COVID-19) pandemic.The LD had brought near to total cut-off emissions from industrial, traffic (road, railways, marine air) energy sectors, though domestic remained fairly unaltered.This provided a unique opportunity delineate impact fossil fuel combustion sources on...

Abstract The impacts of wildfires along the wildland urban interface (WUI) on atmospheric particulate concentrations and composition are an understudied source air pollution exposure. To assess residual 2021 Marshall Fire (Colorado), a wildfire that predominantly burned homes other human-made materials, within fire perimeter escaped fire, we performed combination fine matter (PM 2.5 ) filter sampling chemical analysis, indoor dust collection community scale PurpleAir PM particle number...
To combat the present COVID-19 pandemic, a countrywide lockdown (LD) was imposed in India from 25 March until 31 May 2020.This unique scenario brought decline various anthropogenic activities leading to considerable decrease concentration of several atmospheric pollutants.In this scenario, CSIR-IMMT Bhubaneswar carried out black carbon (BC), PM10 and PM2.5 analysis through optical gravimetric measurements, respectively, during March-May 2020 followed by comparison with previous years...
The COVID-19 pandemic resulted in changed emission regimes all over the world. India also imposed complete lockdown on modes of travel and industrial activities for about 2 months from 25-March-2020 later unlocked these a phased manner. Here, we study signatures emissions changes levels atmospheric trace gases aerosols contributing to air pollution multiple sites India’s capital Delhi covering various unlock phases using satellite data in-situ observations. resulting species were compared...
AbstractAbstractThe present study deals with the determination of iron oxidation rate (IOR) Acidithiobacillus ferrooxidans in presence various heavy metal ions. Initially, IOR this particular strain was enhanced to 718 mg L–1 h–1 by several sets subculturing whole biomass fresh medium. In process, bacterial regeneration time determined be 3˙7 h. The effect ions (Hg, Ag and Pb) on active studied reaction kinetics concentrations solution has been determined. tolerance index culture metals also...
