Investigating the pH of atmospheric fine particles and implications for atmospheric chemistry
… the coastal southwestern U.S. in early summer (CalNex study; PM1 pH = 1.9 ± 0.5 and PM2.5 pH = 2.7 ± 0.3). All studies have consistently found highly acidic PM1 with pH generally below 3. The results are supported by reproducing particle water and gas-particle partitioning of inorganic NH4+, …
