Published in 2020 at "Environmental pollution"

DOI: 10.1016/j.envpol.2020.116305

Abstract: The spatial distributions, fluxes, and environmental effects of non-methane hydrocarbons (NMHCs) were investigated in the Yellow Sea (YS) and the East China Sea (ECS) in spring. The average concentrations of ethane, propane, i-/n-butane, ethylene, propylene… read more here.

Published in 2022 at "Journal of environmental management"

DOI: 10.2139/ssrn.4166138

Abstract: Despite being directly related to anthropogenic consumption and production, researchers have paid less attention to understanding the dynamics of non-methane volatile organic compounds. The primary objective of this research is to investigate the persistence of… read more here.

Published in 2022 at "Toxics"

DOI: 10.3390/toxics10040184

Abstract: The characterization of vehicle exhaust emissions of volatile organic compounds (VOCs) is essential to estimate their impact on the formation of secondary organic aerosol (SOA) and, more generally, air quality. This paper revises and updates… read more here.

Published in 2020 at "Atmospheric Chemistry and Physics"

DOI: 10.5194/acp-20-12133-2020

Abstract: Abstract. In complex atmospheric emission environments such as urban agglomerates, multiple sources control the ambient chemical composition driving air quality and regional climate. In contrast to pristine sites, where reliance on single or a few… read more here.

Published in 2020 at "Atmospheric Chemistry and Physics"

DOI: 10.5194/acp-2020-1108

Abstract: Abstract. Long term measurements of air pollutants represented the footprints of emissions to some extent, which could provide useful and consecutive evolution of emissions. Both atmospheric concentrations and emissions of many air pollutants have been… read more here.
