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 …

Particulate nitrate (pNO 3−) has long been considered a permanent sink for NO x (NO and
NO2), removing a gaseous pollutant that is central to air quality and that influences the …

Satellite observations of tropospheric NO 2 columns are extensively used to infer trends in
anthropogenic emissions of nitrogen oxides (NO x≡ NO+ NO 2), but this may be …

The formation of inorganic nitrate is the main sink for nitrogen oxides (NO x= NO+ NO 2).
Due to the importance of NO x for the formation of tropospheric oxidants such as the …

Nitrous acid (HONO) is a precursor of the hydroxyl radical in the atmosphere, which controls
the degradation of greenhouse gases, contributes to photochemical smog and ozone …

As nitrous acid (HONO) photolysis is an important source of hydroxyl radical (OH),
apportionment of the ambient HONO sources is necessary to better understand atmospheric …

Gaseous nitrous acid (HONO) is a crucial precursor of the hydroxyl (OH) radical, which is a
“detergent” in the atmosphere. Nowadays, HONO formation mechanisms at polluted urban …

Photolysis of nitrate (NO3–) produces reactive nitrogen and oxygen species via three
different channels, forming:(1) nitrogen dioxide (NO2) and hydroxyl radical (• OH),(2) nitrite …

The atmospheric oxidizing capacity is the most important driving force for the chemical
transformation of pollutants in the atmosphere. Traditionally, the atmospheric oxidizing …

The unbridled expansion of advanced agricultural and industrial facilities has led to the
release of large amounts of ammonia (NH3), one of the most pernicious malodorants …
