The high global warming potential of current refrigerants in cooling equipment based on the
vapor-compression cycle has triggered a major effort to find and implement more …

Trifluoroacetic acid (TFA) is a persistent and mobile pollutant that is present ubiquitously in
the environment. As a result of a few studies reporting its presence in pre-industrial samples …

Per-and polyfluoroalkyl substances (PFASs) have been released into the environment for
decades, yet contributions of air emissions to total human exposure, from inhalation and …

Per-and polyfluoroalkyl substances (PFAS) are transported in the atmosphere, leading to
both wet and dry deposition to the surface. The concentrations of 15 PFAS were measured …

A nationwide survey was conducted on per-and polyfluoroalkyl substances (PFASs) in
precipitation across mainland China. Twenty-two PFASs, including precursors to …

The use of vapor compression system-based air-conditioning units is predominant in
conventional fossil-fueled and electric vehicles. Mobile air-conditioning (MAC) units play a …

Atmospheric aerosols play important roles in affecting regional meteorology and air quality
through aerosol direct and indirect effects. Two new chemistry-aerosol options have been …

C1–C4 perfluoroalkyl acids (PFAAs) are highly persistent chemicals that have been found in
the environment. To date, much uncertainty still exists about their sources and fate. The …
