• Increase of nitrooxy organosulfates in firework-related urban aerosols during Chinese New Year's Eve.

  Authors:Qiaorong Xie, Sihui Su, Jing Chen, Yuqing Dai, Siyao Yue, Hang Su, et al.From:Atmospheric Chemistry and Physics (Vol. 21, Issue 14) Peer-Reviewed

  July 30, 2021238 words Brief article Little is known about the formation processes of nitrooxy organosulfates (OSs) by nighttime chemistry. Here we characterize nitrooxy OSs at a molecular level in firework-related aerosols in urban Beijing during Chinese...

• Development of an antioxidant assay to study oxidative potential of airborne particulate matter.

  Authors:Pourya Shahpoury, Tom Harner, Gerhard Lammel, Steven Lelieveld, Haijie Tong, and Jake WilsonFrom:Atmospheric Measurement Techniques (Vol. 12, Issue 12) Peer-Reviewed

  Dec. 9, 2019287 words Brief article Oxidative potential is a measure of redox activity of airborne particulate matter (PM) and is often used as a surrogate to estimate one form of PM toxicity. The evaluation of oxidative potential in a physiologically...

• Quantification of environmentally persistent free radicals and reactive oxygen species in atmospheric aerosol particles

  Authors:Andrea M. Arangio, Haijie Tong, Joanna Socorro, and Manabu ShiraiwaFrom:Atmospheric Chemistry and Physics (Vol. 16, Issue 20) Peer-Reviewed

  Oct. 26, 2016298 words Brief article Fine particulate matter plays a central role in the adverse health effects of air pollution. Inhalation and deposition of aerosol particles in the respiratory tract can lead to the release of reactive oxygen species...

• Mixing state of oxalic acid containing particles in the rural area of Pearl River Delta, China: implications for the formation mechanism of oxalic acid

  Authors:Chunlei Cheng, Mei Li, Chak K. Chan, Haijie Tong, Changhong Chen, Duohong Chen, et al.From:Atmospheric Chemistry and Physics (Vol. 17, Issue 15) Peer-Reviewed

  Aug. 8, 2017342 words Brief article, Repor... The formation of oxalic acid and its mixing state in atmospheric particulate matter (PM) were studied using a single-particle aerosol mass spectrometer (SPAMS) in the summer and winter of 2014 in Heshan, a supersite in...

• Molecular characterization of firework-related urban aerosols using Fourier transform ion cyclotron resonance mass spectrometry.

  Authors:Qiaorong Xie, Sihui Su, Shuang Chen, Yisheng Xu, Dong Cao, Jing Chen, et al.From:Atmospheric Chemistry and Physics (Vol. 20, Issue 11) Peer-Reviewed

  June 10, 2020264 words Brief article Firework (FW) emission has strong impacts on air quality and public health. However, little is known about the molecular composition of FW-related airborne particulate matter (PM), especially the organic fraction. Here...

• Aqueous-phase reactive species formed by fine particulate matter from remote forests and polluted urban air.

  Authors:Haijie Tong, Fobang Liu, Alexander Filippi, Jake Wilson, Andrea M. Arangio, Yun Zhang, et al.From:Atmospheric Chemistry and Physics (Vol. 21, Issue 13) Peer-Reviewed

  July 9, 2021420 words Article In the aqueous phase, fine particulate matter can form reactive species (RS) that influence the aging, properties, and health effects of atmospheric aerosols. In this study, we explore the RS yields of aerosol samples...

• MIMiX: a Multipurpose In situ Microreactor system for X-ray microspectroscopy to mimic atmospheric aerosol processing.

  Authors:Jan-David Förster, Christian Gurk, Mark Lamneck, Haijie Tong, Florian Ditas, Sarah S. Steimer, et al.From:Atmospheric Measurement Techniques (Vol. 13, Issue 7) Peer-Reviewed

  July 9, 2020248 words Brief article The dynamic processing of aerosols in the atmosphere is difficult to mimic under laboratory conditions, particularly on a single-particle level with high spatial and chemical resolution. Our new microreactor system for...

• Hydroxyl radicals from secondary organic aerosol decomposition in water

  Authors:Haijie Tong, Andrea M. Arangio, Pascale S. J. Lakey, Thomas Berkemeier, Fobang Liu, Christopher J. Kampf, et al.From:Atmospheric Chemistry and Physics (Vol. 16, Issue 3) Peer-Reviewed

  Feb. 15, 2016223 words Brief article We found that ambient and laboratory-generated secondary organic aerosols (SOA) form substantial amounts of OH radicals upon interaction with liquid water, which can be explained by the decomposition of organic...
