This chapter concerns atmospheric changes in ozone-depleting substances (ODSs), such
as chlorofluorocarbons (CFCs), halons, chlorinated solvents (eg, CCl 4 and CH 3 CCl 3) and …

Chloroform contributes to the depletion of the stratospheric ozone layer. However, due to its
short lifetime and predominantly natural sources, it is not included in the Montreal Protocol …

With the successful implementation of the Montreal Protocol on Substances that Deplete the
Ozone Layer, the atmospheric abundance of ozone-depleting substances continues to …

Emissions of chloroform (CHCl3), a short-lived halogenated substance not currently
controlled under the Montreal Protocol on Substances that Deplete the Ozone Layer, are …

Large and effective reductions in emissions of long-lived ozone-depleting substance (ODS)
are being achieved through the Montreal Protocol, the effectiveness of which can be seen in …

This study aims to evaluate the air quality on Langkawi Island, a famous tourist destination in
Malaysia, using 13 years of data (1999–2011) recorded by the Malaysian Department of …

We exploited a novel sampling vehicle, a multi-rotor drone carrying a remote-controlled
whole air sampling device, to collect aerial samples with high sample integrity and …

Benzene, toluene, ethylbenzene and xylene isomers (BTEX) are volatile organic air
pollutants of concern which arise from natural and anthropogenic sources. This study aims …

Abstract Dichloromethane (CH2Cl2) and perchloroethylene (C2Cl4) are chlorinated very
short lived substances (Cl‐VSLS) with anthropogenic sources. Recent studies highlight the …

Abstract Chloroform (CHCl3), dichloromethane (CH2Cl2), perchloroethylene (C2Cl4), and 1,
2‐dichloroethane (C2H4Cl2) are chlorinated Very Short‐Lived Substances (Cl‐VSLS) with a …
