Crucial Role for Outdoor Chemistry in Ultrafine Particle Formation in Modern Office Buildings

27-Aug-2015 | Nicola Carslaw; Mike Ashmore; Andrew C. Terry; David C. Carslaw, Environmental Science & Technology, 2015

In the developed world, we spend most of our time indoors, where we receive the majority of our exposure to air pollution. This paper reports model simulations of PM2.5 and ozone concentrations in identical landscape offices in three European cities: Athens, Helsinki, and Milan. We compare ...

Theoretical Study of the Reactions of Criegee Intermediates with Ozone, Alkylhydroperoxides, and Carbon Monoxide

26-Aug-2015 | Luc Vereecken; Andrew R Rickard; Mike Newland; William Bloss, Physical Chemistry Chemical Physics, 2015

The reaction of Criegee intermediates (CI) with ozone, O3, has been re-examined with higher levels of theory, following earlier reports that O3 could be a relevant sink of CI. The updated rate coefficients indicate that the reaction is somewhat slower than originally anticipated, and is not ...

Filament-Assisted Impulsive Raman Spectroscopy of Ozone and Nitrogen Oxides

25-Aug-2015 | Erin T. McCole Dlugosz; Reginald Fisher; Aleksey Filin; Dmitri A. Romanov; Johanan H. Odhner; Robert J. Levis, Journal of Physical Chemistry A, 2015

The filament-assisted impulsive Raman spectra of ozone, nitric oxide, and nitrogen dioxide are presented. The Raman response as a function of ozone concentration scales as N2, where N is the number of oscillators in the interaction region. The system described has a detection limit of ∼300 ppm ...

Protein Cross-Linking and Oligomerization through Dityrosine Formation upon Exposure to Ozone

25-Aug-2015 | Christopher J. Kampf; Fobang Liu; Kathrin Reinmuth-Selzle; Thomas Berkemeier; Hannah Meusel; Manabu Shiraiwa; Ulrich ..., Environmental Science & Technology, 2015

Air pollution is a potential driver for the increasing prevalence of allergic disease, and post-translational modification by air pollutants can enhance the allergenic potential of proteins. Here, the kinetics and mechanism of protein oligomerization upon ozone (O3) exposure were studied in ...

Preparation of a Silanone through Oxygen Atom Transfer to a Stable Cyclic Silylene

20-Aug-2015 | Michael M. Linden, Hans Peter Reisenauer, Dennis Gerbig, Miriam Karni, Annemarie Schäfer, Thomas Müller, Yitzhak Ape ..., Angewandte Chemie International Edition, 2015

Abstract We report the evaporation of a stable cyclic silylene and its oxidation (with ozone or N2O) through oxygen atom transfer to form the corresponding silanone under matrix isolation conditions. As uncomplexed silanones are rare owing to their very high reactivity, this method provides an ...

Molecules, Vol. 20, Pages 15098-15107: Addition of CFCl3 to Aromatic Aldehydes via in Situ Grignard Reaction

18-Aug-2015 | Barkakaty, Balaka ; Talukdar, Bandana ; Lokitz, Bradley S., Molecules, 2015

Synthetic modification of trichlorofluoromethane (CFCl3) to non-volatile and useful fluorinated precursors is a cost-effective and an environmentally benign strategy for the safe consumption/destruction of the ozone depleting potential of the reagent. In this report, we present a novel method for ...

Environmental Pollutant Ozone Causes Damage to Lung Surfactant Protein B (SP-B)

13-Aug-2015 | Joanna M. Hemming; Brian R. Hughes; Adrian R. Rennie; Salvador Tomas; Richard A. Campbell; Arwel V. Hughes; Thomas A ..., Biochemistry, 2015

Lung surfactant protein B (SP-B) is an essential protein found in the surfactant fluid at the air–water interface of the lung. Exposure to the air pollutant ozone could potentially damage SP-B and lead to respiratory distress. We have studied two peptides, one consisting of the N-terminus of SP-B ...

Indirect nitrous oxide emissions from streams within the US Corn Belt scale with stream order [Agricultural Sciences]

11-Aug-2015 | Peter A. Turner; Timothy J. Griffis; Xuhui Lee; John M. Baker; Rodney T. Venterea; Jeffrey D. Wood, Proceedings of the National Academy of Sciences current issue, 2015

N2O is an important greenhouse gas and the primary stratospheric ozone depleting substance. Its deleterious effects on the environment have prompted appeals to regulate emissions from agriculture, which represents the primary anthropogenic source in the global N2O budget. Successful ...

Development of Prediction Models for the Reactivity of Organic Compounds with Ozone in Aqueous Solution by Quantum Chemical Calculations: The Role of Delocalized and Localized Molecular Orbitals

07-Aug-2015 | Minju Lee; Saskia G. Zimmermann-Steffens; J. Samuel Arey; Kathrin Fenner; Urs von Gunten, Environmental Science & Technology, 2015

Second-order rate constants (kO3) for the reaction of ozone with micropollutants are essential parameters for the assessment of micropollutant elimination efficiency during ozonation in water and wastewater treatment. Prediction models for kO3 were developed for aromatic compounds, olefins, and ...
