Seasonal Aerosol Acidity, Liquid Water Content and Their Impact on Fine Urban Aerosol in SE Canada

Autor: Andrea M. Arangio, Pourya Shahpoury, Ewa Dabek-Zlotorzynska, Athanasios Nenes

Publikováno v: Atmosphere, Vol 13, Iss 7, p 1012 (2022)

This study explores the drivers of aerosol pH and their impact on the inorganic fraction and mass of aerosol in the S.E. Canadian urban environments of Hamilton and Toronto, Ontario. We find that inter-seasonal pH variability is mostly driven by temp

Seasonal aerosol acidity and liquid water content: impact on aerosol concentration and nitrogen deposition fluxes in a urban Canadian environment

Autor: Athanasios Nenes, Andrea M. Arangio, Pourya Shahpoury, Ewa Dabek-Zlotorzynska

Aerosol acidity and liquid water content (LWC) affect aerosol concentration and composition as well as the fate of the precursor compounds ammonia (NH3) and nitric acid (HNO3) [1,2]. Together with temperature, aerosol acidity and LWC determine the ga

Characterization of Organic Matter in PM2.5 sampled on different filter by FITR and Electrospray ATR-FTIR

Autor: Matteo Reggente, Christoph Hüglin, Amir Yazdani, Satoshi Takahama, Athanasios Nenes, Claudia Zellweger-Fasi, Andrea M. Arangio

Atmospheric particulate matter (PM) is composed of up to 90% of organic matter [1]. Chemical characterization of PM organic fraction can be achieved by transmission mode Fourier transform infrared spectroscopy (TM-FTIR). FTIR is fast and inexpensive

Oxygenated and Nitrated Polycyclic Aromatic Hydrocarbons in Ambient Air—Levels, Phase Partitioning, Mass Size Distributions, and Inhalation Bioaccessibility

Autor: Jiří Novák, Jan Kuta, Gerhard Lammel, Marco Wietzoreck, Roman Prokeš, Andrea M. Arangio, Petr Kukučka, Cecilia Leoni, Petra Přibylová, Zoran Kitanovski, Ondřej Sáňka, Jan Hovorka, Alexander Filippi, Pourya Shahpoury, Haijie Tong, Garry Codling

Publikováno v: Environmental Science & Technology

Among the nitrated and oxygenated polycyclic aromatic hydrocarbons (NPAHs and OPAHs) are some of the most hazardous substances to public health, mainly because of their carcinogenicity and oxidative potential. Despite these concerns, the concentratio

Cloud droplet activation through oxidation of organic aerosol influenced by temperature and particle phase state

Autor: Ulrich Pöschl, Jian Wang, Andrea M. Arangio, Daniel A. Knopf, J. H. Slade, Manabu Shiraiwa, Hang Su

Publikováno v: Geophysical Research Letters. 44:1583-1591

Chemical aging of organic aerosol (OA) through multiphase oxidation reactions can alter their cloud condensation nuclei (CCN) activity and hygroscopicity. However, the oxidation kinetics and OA reactivity depend strongly on the particle phase state,

Reactive oxygen species formed in aqueous mixtures of secondary organic aerosols and mineral dust influencing cloud chemistry and public health in the Anthropocene

Autor: Christopher J. Kampf, Ulrich Pöschl, Haijie Tong, Joanna Socorro, Pascale S. J. Lakey, William H. Brune, Thomas Berkemeier, Andrea M. Arangio, Manabu Shiraiwa

Publikováno v: Faraday Discussions. 200:251-270

Mineral dust and secondary organic aerosols (SOA) account for a major fraction of atmospheric particulate matter, affecting climate, air quality and public health. How mineral dust interacts with SOA to influence cloud chemistry and public health, ho

Publikováno v: Environmental Science & Technology.

Reactive oxygen species (ROS) play a central role in adverse health effects of air pollutants. Respiratory deposition of fine air particulate matter can lead to the formation of ROS in epithelial lining fluid, potentially causing oxidative stress and
