Gas-phase composition and secondary organic aerosol formation from standard and particle filter-retrofitted gasoline direct injection vehicles investigated in a batch and flow reactor
Simone M. Pieber,Simone M. Pieber,Nivedita K. Kumar,Felix Klein,Pierre Comte,Deepika Bhattu,Josef Dommen,Emily A. Bruns,Doǧuşhan Kılıç,Doǧuşhan Kılıç,Imad El Haddad,Alejandro Keller,Jan Czerwinski,Norbert V. Heeb,Urs Baltensperger,Jay G. Slowik,André S. H. Prévôt +16 more
TL;DR: In this paper, the authors investigated primary emissions and secondary organic aerosol (SOA) from four GDI vehicles, two of which were also retrofitted with a prototype gasoline particulate filter (GPF).
New Exposure System To Evaluate the Toxicity of (Scooter) Exhaust Emissions in Lung Cells in Vitro
Loretta Müller,Pierre Comte,Jan Czerwinski,Markus Kasper,Andreas Mayer,Peter Gehr,Heinz Burtscher,Jean-Paul Morin,Athanasios G. Konstandopoulos,Barbara Rothen-Rutishauser +9 more
TL;DR: It was shown that the described exposure system can be used to evaluate the toxic potential of total exhaust emissions and inflammatory chemo- and cytokine concentrations in the medium of exposed cells were significantly higher at the 12 h postexposure time point.

Bioethanol Blending Reduces Nanoparticle, PAH, and Alkyl- and Nitro-PAH Emissions and the Genotoxic Potential of Exhaust from a Gasoline Direct Injection Flex-Fuel Vehicle
María Isabel Vera Muñoz,Norbert V. Heeb,Regula Haag,Peter Honegger,Kerstin Zeyer,Joachim Mohn,Pierre Comte,Jan Czerwinski +7 more
TL;DR: Emissions of a flex-fuel Euro-5 GDI vehicle operated with gasoline and two ethanol/gasoline blends are compared and Ethanol blending appears to reduce genotoxic emissions on this specific flex- fuel G DI vehicle; however, other GDI vehicles types should be analyzed.

TL;DR: The repeated exposure of different GDI exhausts using two different cell culture models mimicking the human airway led to a significant increase in HMOX1 and TNFa gene expression in the multi-cellular model, showing the responsiveness of the system towards gasoline engine exhaust upon prolonged exposure.

Co-formation and co-release of genotoxic PAHs, alkyl-PAHs and soot nanoparticles from gasoline direct injection vehicles
María Isabel Vera Muñoz,Regula Haag,Peter Honegger,Kerstin Zeyer,Joachim Mohn,Pierre Comte,Jan Czerwinski,Norbert V. Heeb +7 more
TL;DR: In this paper, a fleet of 7 Gasoline Direct Injection (GDI) vehicles with Euro-3, 4, 5, 6, 7, 8, 8.1, 9.6, 0.02 and 0.2 µg/μg/km−1 emissions were tested in the cold worldwide harmonized light vehicle test cycle.
