TL;DR: In this article, the authors compared surface air quality data in Delhi during four phases of lockdown and the first phase of the restriction easing period (25 March to 30 June 2020) with data from a baseline period (2018-2019).

TL;DR: Results of comprehensive analyses of data from the first 122 commercially available wireless environmental pervasive sensors (motes) developed by Newcastle University and deployed in England clearly illustrates the benefits and added value of pervasive concentration measurement in urban micro environments with potential to effectively evaluate human exposure to transport-related emissions.

TL;DR: Investigation of the measured roadside air-pollutant concentrations in terms of the traffic flow levels, the orientation of the street to the prevailing wind, the wind speed, temperature and barometric pressure confirms the complexity of the physical and chemical processes that govern roadside concentrations.

TL;DR: In this article, an attempt has been made to investigate the exhaust and non-exhaust emissions emitted from selected roads in Delhi city, based on the vehicular density per hour and speed, three categories of roads have been considered in the present study.
