TL;DR: It is shown that human exposure to carbonaceous aerosols of fossil origin is transitioning away from transportation-related sources and toward VCPs, and the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted.
Journal ArticleDOI
Aging Effects on Biomass Burning Aerosol Mass and Composition: A Critical Review of Field and Laboratory Studies
Anna L. Hodshire,Ali Akherati,Matthew J. Alvarado,Benjamin Brown-Steiner,Shantanu H. Jathar,Jose L. Jimenez,Sonia M. Kreidenweis,C. R. Lonsdale,Timothy B. Onasch,Amber M. Ortega,Jeffrey R. Pierce +10 more
TL;DR: This review summarizes available observations of aging-related biomass burning aerosol mass concentrations and composition markers, and discusses four broad hypotheses to explain variability within and between field and laboratory campaigns.
Journal ArticleDOI
Oxygenated Aromatic Compounds are Important Precursors of Secondary Organic Aerosol in Biomass-Burning Emissions.

Onasch,Scott C. Herndon,Walter B. Knighton,Christopher D. Cappa,Michael J. Kleeman,Christopher Y. Lim,Jesse H. Kroll,Jeffrey R. Pierce,Shantanu H. Jathar +20 more
TL;DR: A state-of-the-science model to simulate the photochemical formation of secondary organic aerosol (SOA) from biomass burning emissions observed in dry (RH<20%) environmental chamber experiments finds that oxygenated aromatic compounds account for slightly less than 60% of the SOA formed.
Journal ArticleDOI
Experimental study of ultrasonic radiation on growth kinetic of asphaltene aggregation and deposition
TL;DR: In this article, the effects of duration of ultrasonic radiation, power and stability on asphaltene aggregation were evaluated from a kinetic point of view, and the optimal exposure time and power for the oil sample were obtained 150 sec and 40 W, respectively.
Journal ArticleDOI
Simulating secondary organic aerosol in a regional air quality model using the statistical oxidation model – Part 3: Assessing the influence of semi-volatile and intermediate-volatility organic compounds and NO x

TL;DR: In this article, the UCD/CIT (University of California at Davis/California Institute of Technology) chemical transport model was updated to include a semi-volatile and reactive treatment of primary organic aerosol (POA), emissions from IVOCs, and the NOx influence on SOA formation.
