High-resolution mapping of regional traffic emissions using land-use machine learning models [PDF]

Atmospheric Chemistry and Physics, 2022
On-road vehicle emissions are a major contributor to significant atmospheric pollution in populous metropolitan areas. We developed an hourly link-level emissions inventory of vehicular pollutants using two land-use machine learning methods based on road

Influencing factors of the gas–particle distribution of oxygenated organic molecules in the urban atmosphere and deviation from equilibrium partitioning: a random forest model study [PDF]

Atmospheric Chemistry and Physics
Gas–particle partitioning governs the fate of oxygenated organic molecules (OOMs) and the formation of organic aerosols. We employed a Chemical Ionization Mass Spectrometer equipped with a Filter Inlet for Gases and AEROsol (FIGAERO-CIMS) to measure the ...

Characteristics of Black Carbon Particle-Bound Polycyclic Aromatic Hydrocarbons in Two Sites of Nanjing and Shanghai, China

Atmosphere, 2020
Airborne polycyclic aromatic hydrocarbons (PAHs) are of great concern to human health due to their potential high toxicity. Understanding the characteristics and sources of PAHs, as well as the governing factors, is therefore critical.

Air Pollution Monitoring System [PDF]

International Journal of Trend in Scientific Research and Development, 2018
Particulate matter is the most dangerous form of air pollution because it does not only affects the human health but also has an impact on the earth's climate and precipitation levels. This paper proposes an easy and cost efficient method to measure dust particles, volume of CO carbon monoxide , temperature and humidity for weather forecast.

Monitoring Air Pollution Variability during Disasters

Atmosphere, 2021
National environmental regulations lack short-term standards for variability in fine particulate matter (PM2.5); they depend solely on concentration-based standards.
