Acidity, defined as pH, is a central component of aqueous chemistry. In the atmosphere, the
acidity of condensed phases (aerosol particles, cloud water, and fog droplets) governs the …

Anthropogenic emissions and land use changes have modified atmospheric aerosol
concentrations and size distributions over time. Understanding preindustrial conditions and …

Urban air pollution represents one of the greatest environmental challenges facing mankind
in the 21st century. 1, 2 Noticeably, many develo** countries, such as China and India …

This Review aims to summarize the current understanding of bulk tropospheric aqueous-
phase chemistry. Because a complete review of all developments in this area would be …

Secondary organic aerosol (SOA) accounts for a significant fraction of ambient tropospheric
aerosol and a detailed knowledge of the formation, properties and transformation of SOA is …

Amines are emitted by a wide range of sources and are ubiquitous atmospheric organic
bases. Approximately 150 amines and about 30 amino acids have been identified in the …

Secondary organic aerosol (SOA), particulate matter composed of compounds formed from
the atmospheric transformation of organic species, accounts for a substantial fraction of …

The acidity of aqueous atmospheric solutions is a key parameter driving both the partitioning
of semi-volatile acidic and basic trace gases and their aqueous-phase chemistry. In addition …

Dimeric accretion products have been observed both in atmospheric aerosol particles and in
the gas phase. With their low volatilities, they are key contributors to the formation of new …

Organosulfates of isoprene, α-pinene, and β-pinene have recently been identified in both
laboratory-generated and ambient secondary organic aerosol (SOA). In this study, the …
