Short summary
PM2.5 filter samples have been collected in three megacities at the middle and lower reaches of the Yangtze River: Wuhan, Nanjing, and Shanghai. The samples were analyzed using ultra-high-performance liquid chromatography coupled with Orbitrap mass spectrometry, which allowed for detection of about 200 formulas of particulate organosulfates, including dozens of formulas of nitrooxy-organosulfates, with various numbers of isomers for each tentatively determined formula at each location.
