Abstract:
... Aerosol volatility has a substantial impact on gas-particle partitioning, aging process and hence brown carbon (BrC) absorption. Here we analyzed single-particle volatility in winter in Beijing using a thermodenuder coupled with a single particle aerosol mass spectrometer along with a suite of collocated measurements. Our results showed that elemental carbon, metals, organic nitrogen (ON) were the ...

Recent studies found that both nitrite (NO₂–) and ammonium (NH₄⁺) lead to nitrophenolic byproducts in SO₄•– oxidation processes, during which NO₂• generated through the oxidation of the inorganic nitrogen by SO₄•– is the key nitrating agent. This study demonstrates that the formation of phenoxy radicals to which NO₂• can be incorporated immediately is another governing factor. Two types of sites h ...
