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

As primary emissions have been declining in recent decades in China, secondary pollution,
like ozone (O 3) and secondary aerosols are main pollutants deteriorating air quality. The …

Precipitation plays a pivotal role in wet deposition, significantly affecting aerosol purification.
The efficacy of precipitation in removing aerosols depends on its type and the characteristics …

In this study, for the purpose of improving the removal effect of biochar on nitrate in
wastewater at lower temperature, MgFe layered double hydroxides (MgFe-LDHs) were …

Understanding the sources and formation mechanisms of nitrate in PM 2.5 is important for
effective and precise prevention and control of particulate matter pollution. In this study, we …

Accurate fine-mode and coarse-mode aerosol knowledge is crucial for understanding their
impacts on the climate and Earth's ecosystems. However, current satellite-based Fine-Mode …

As a major component of brown carbon (BrC), nitrated aromatic compounds (NACs) have a
significant role in the atmosphere's ability to absorb light. However, the sources and major …

Light-absorbing carbonaceous aerosols are important contributors to both air pollution and
radiative forcing. However, their abundances and sources remain poorly constrained, as can …

Fireworks are banned in many Chinese cities but never eliminated, reflecting strong public
demand on this traditional activity for festival celebrations. On the other hand, the …

Dual isotopes of nitrogen and oxygen of NO 3− are crucial tools for quantifying the formation
pathways and precursor NO x sources contributing to atmospheric nitrate. However, further …
