The concentration of fine particulate matter (PM2. 5) across China has decreased by 30–
50% over the period 2013–2018 due to stringent emission controls. However, the nitrate …

Abstract Fine particulate matter (PM2. 5) has been the primary air pollutant and the fourth
leading risk factor for disease and death in the world. Exposure to PM2. 5 is related to …

The key areas of China's urbanization process have gradually shifted from urban areas to
county-level units. Correspondingly, air pollution in county towns may be heavier than in …

As the primary carrier of harmful elements, road sediment poses severe hazards to human
health and ecological environment, especially in megacities. Based on the industrial cities in …

Studying the source-specific health risks of trace metals in PM 2.5 is important for controlling
its emission sources that are hazardous to human health. In this study, PM 2.5-bound trace …

Carbonaceous aerosol is one of the main components of atmospheric particulate matter,
which is of great significance due to its role in climate change, earth's radiation balance …

The experimental evidences linking PM 2.5 exposure to weight status disorder and the
associated mechanisms were lacked. Here, we demonstrated exposure of 198.52 μg/m 3 …

Finer road dust has attracted considerable attention due to its more serious environmental
detriment and ecological–health risk than coarser road dust. In this study, the concentrations …

Ammonium salt is an important component of particulate matter with aerodynamic diameter
less than 2.5 µm (PM2. 5) and has significant impacts on air quality, climate, and natural …

The atmospheric oxidizing capacity (AOC) is the essential driving force of tropospheric
chemistry, but its quantitative representation remains limited. This study presents the …
