Journal ArticleDOI
Ascorbate oxidation by iron, copper and reactive oxygen species: review, model development, and derivation of key rate constants.
Jiaqi Shen,Paul T. Griffiths,Steven J. Campbell,Battist Utinger,Markus Kalberer,Markus Kalberer,Suzanne E. Paulson +6 more
TL;DR: In this paper, the authors show that micromolar concentrations of iron(III) and copper(II) are more important sinks for ascorbic acid (both AH2 and AH-) than reactive oxygen species.
Journal ArticleDOI
Atmospheric conditions and composition that influence PM2.5 oxidative potential in Beijing, China.
Steven J. Campbell,Steven J. Campbell,Kate Wolfer,Battist Utinger,Joe Westwood,Zhi Hui Zhang,Zhi Hui Zhang,Nicolas Bukowiecki,Sarah S. Steimer,Tuan V. Vu,Jingsha Xu,Nicholas Straw,Steven Thomson,Atallah Elzein,Yele Sun,Di Liu,Di Liu,Linjie Li,Pingqing Fu,Alastair C. Lewis,Roy M. Harrison,William J. Bloss,Miranda Loh,Mark R. Miller,Zongbo Shi,Markus Kalberer,Markus Kalberer +26 more
TL;DR: This study constitutes one of the most extensive and comprehensive composition datasets currently available and provides a unique opportunity to explore chemical variations in PM2.5 and shows that mass-normalised OP provides a more nuanced picture of compositional drivers and sources of OP compared to volume- normalised analysis.
Journal ArticleDOI
Development of a Physiologically Relevant Online Chemical Assay To Quantify Aerosol Oxidative Potential.
Steven J. Campbell,Steven J. Campbell,Battist Utinger,Battist Utinger,Daniel M. Lienhard,Suzanne E. Paulson,Jiaqi Shen,Paul T. Griffiths,Angharad C Stell,Markus Kalberer,Markus Kalberer +10 more
TL;DR: A novel online method based on ascorbic acid chemistry, an anti-oxidant prevalent in the lung, is developed, demonstrating that even at this early stage of development, the online method is capable of measuring the OP of PM in polluted urban environments and smog chamber studies.
Posted ContentDOI
Are reactive oxygen species (ROS) a suitable metric to predict toxicity of carbonaceous aerosol particles
Zhi Hui Zhang,Zhi Hui Zhang,Elena Hartner,Battist Utinger,Benjamin Gfeller,Andreas Paul,Martin Sklorz,Hendryk Czech,Bin Xia Yang,Xin Yi Su,Gert Jakobi,Jürgen Orasche,Jürgen Schnelle-Kreis,Seongho Jeong,Thomas Gröger,Michal Pardo,Thorsten Hohaus,Thomas Adam,Astrid Kiendler-Scharr,Yinon Rudich,Ralf Zimmermann,Markus Kalberer,Markus Kalberer +22 more
TL;DR: In this paper, the formation of reactive oxygen species (ROS) in secondary organic aerosols (SOA) generated from organic compounds that represent anthropogenic (naphthalene, SOANAP) and biogenic (β-pinene and SOAβPIN) precursors was investigated using an online particle-bound ROS instrument (OPROSI).

Yinon Rudich,Thomas Gröger,Martin Sklorz,Zhi-Hui Zhang,Hendryk Czech,Thorsten Hohaus,Michal Pardo,Gert Jakobi,Jürgen Orasche,Battist Utinger,Benjamin Gfeller,Petra Künkel,Aurora A. Ramírez-Álvarez,Xuejun Fan,Michelle C. Kegler,Ayman Khattab,Gopalram Keerthiga,Benjamin A. Toll,Akmal Yuldashev,Hayitov Jumaqul Negmatovich,[ALARM] +20 more
TL;DR: In this paper , an online particle-bound ROS instrument (OPROSI) was developed to quantify particle-induced reactive oxygen species (ROS) in secondary organic aerosols (SOAs) generated from organic compounds that represent anthropogenic and biogenic precursors.
