Ammoniated aerosols are important for urban air quality, but emissions of the key precursor
NH3 are not well quantified. Mobile laboratory observations are used to characterize fleet …

Volatile organic compounds (VOCs) emitted by a human body form a chemical signature
capable of providing invaluable information on the physiological status of an individual and …

Agricultural activities are a major source contributing to NH 3 emissions in Shanghai and
most other regions of China; however, there is a long-standing and ongoing controversy …

To assess the relative contributions of traffic emission and other potential sources to high
levels of atmospheric ammonia (NH3) in urban areas in the wintertime, atmospheric NH3 …

Santiago is one of the largest cities in South America and has experienced high fine
particulate matter (PM 2.5) concentrations in fall and winter months for decades. To better …

Continuous measurements of PM 10, PM 2.5, and PM 1 concentrations were carried out by
collocating a GRIMM Aerosol Laser Spectrometer model 11-C as a reference instrument and …

To investigate chemical characteristics, abatement mechanisms and regional transport of
atmospheric pollutants during the COVID-19 outbreak control period in the Yangtze River …

ABSTRACTTo understand the air pollution problem in megacities such as Beijing, field
measurement investigating the variation of NH3 and its association with PM2. 5 chemical …

The Paris megacity experiences frequent particulate matter (ie PM 2.5, particulate matter
with a diameter less than 2.5 µ m) pollution episodes in spring (March–April). At this time of …

The presence of atmospheric inorganic pollutants, such as SO2 and NH3 could affect the
nanoparticles formation and their atmospheric abundance. In the present study, the joint …
