TL;DR: It is concluded that urban vegetation can facilitate broad health benefits, but there is little empirical evidence linking these benefits to air pollution reduction by urban vegetation, and appreciable efforts are needed to establish the underlying policies, design and engineering guidelines governing its deployment.

TL;DR: Investigating impacts of COVID-19 mitigation measures on ambient air quality in five Indian cities using in-situ measurements from 2015 to 2020 indicated improvements in air quality may be considered a temporary lockdown benefit as revitalising the economy could reverse this trend.

TL;DR: In this article, the authors obtained the spatiotemporal characteristics of daily-averaged particulate matter (PM10 and PM2.5) and trace gases (NOX,O3,SO2, and CO) within a network of 12 air quality monitoring stations located over 2000 km2 across Delhi-NCR from January 2014 to December 2017.

TL;DR: It was concluded that car-users in the least affluent cities experienced disproportionately higher in-car PM2.5 exposures, indicating filter effectiveness in removing coarse particles and a need for filters that limit the ingress of fine particles.

TL;DR: The database of PM emission profiles developed from the sources investigated can be used to assist source apportionment studies for accurate quantification of the causes of air pollution and hence assist governmental bodies in formulating relevant countermeasures.
