Aerosol ultra-fine and nano-particles are playing essential roles in the evolution of the Earth
environment because of their deep connections to the chemical conversions and solar …

Heating is a major source of air pollution. To improve air quality, a range of clean heating
policies were implemented in China over the past decade. Here, we evaluated the impacts …

In recent decades, air pollution has become an important environmental problem in the
megacities of eastern China. How to control air pollution in megacities is still a challenging …

Abstract A long-term (2013–2019) PM 2.5 speciation dataset measured in Tianjin, the
largest industrial city in northern China, was analyzed with dispersion normalized positive …

The air quality in China has been improved substantially, however fine particulate matter
(PM 2.5) still remain at a high level in many areas. PM 2.5 pollution is a complex process …

Fine-particle pollution associated with high sulfate and secondary organic aerosol (SOA)
contents still occurs in winter, despite considerable reductions in precursor emissions in …

Biomass burning emits large numbers of organic aerosol particles, a subset of which are
called tarballs (TBs). TBs possess a spherical morphology and unique physical, chemical …

According to atmospheric modeling and satellite observations, cold fronts can cause trans‐
regional transport (TRT) of haze particles from the North China Plain (NCP) to Yangtze River …

Understanding the physicochemical properties of atmospheric particles and the refined
source apportionment become a vital foundation for targeted control of air pollution. The …

Although air quality guidelines generally use the atmospheric concentration of fine
particulate matter (PM 2.5) as a metric for air pollution evaluation and management, the fact …
