Upper tropospheric water vapour and its interaction with cirrus clouds as seen from IAGOS long-term routine in-situ observations

21-Feb-2017 | Andreas Petzold; Martina Krämer; Patrick Neis; Christian Rolf; Susanne Rohs; Florian Berkes; Herman G. J. Smit; Mart ..., Faraday Discussions, 2017

IAGOS (In-service Aircraft for a Global Observing System) performs long-term routine in-situ observations of atmospheric chemical composition (ozone, CO, NOx, NOy, CO2, CH4), water vapour, aerosols, clouds and temperature on a global scale by operating compact instruments on board of passenger ...

The Essential Role for Laboratory Studies in Atmospheric Chemistry

17-Feb-2017 | James B. Burkholder; Jonathan P. D. Abbatt; Ian Barnes; James M. Roberts; Megan L. Melamed; Markus Ammann; Allan K. ..., Environmental Science & Technology, 2017

Laboratory studies of atmospheric chemistry characterize the nature of atmospherically relevant processes down to the molecular level, providing fundamental information used to assess how human activities drive environmental phenomena such as climate change, urban air pollution, ecosystem health, ...

Oxidation Potentials of Phenols and Anilines: Correlation Analysis of Electrochemical and Theoretical Values

14-Feb-2017 | Ania S. Pavitt; Eric Bylaska; Paul G Tratnyek, Journal of Environmental Monitoring, 2017

Phenols and anilines have been studied extensively as reductants of environmental oxidants (such as manganese dioxide) and as reductates (e.g., model contaminants) that are transformed by environmental oxidants (ozone, triple organic matter, etc.). The thermodynamics and kinetics of these ...

Effects of halogens on European air-quality

14-Feb-2017 | Tomás Sherwen; Mathew John J Evans; Roberto Sommariva; Lloyd D. J. Hollis; Stephen Ball; Paul Monks; Christopher Ree ..., Faraday Discussions, 2017

Halogens (Cl, Br) have a profound influence on stratospheric ozone (O3). They (Cl, Br and I) have recently also been shown to impact the troposphere, notably by reducing the mixing ratios of O3 and OH. Their potential for impacting regional air-quality is less well understood. We explore the ...

IJERPH, Vol. 14, Pages 189: Gaseous Air Pollution and the Risk for Stroke Admissions: A Case-Crossover Study in Beijing, China

14-Feb-2017 | Huang, Fangfang ; Luo, Yanxia ; Tan, Peng ; Xu, Qin ; Tao, Lixin ; Guo, Jin ; Zhang, Feng ; Xie, Xueqin ; Guo, Xiuhua, International Journal of Environmental Research and Public Health, 2017

Background: Though increasing evidence supports association between gaseous air pollution and stroke, it remains unclear whether the effects differ in season, sex and age. The aim of this study was to examine the associations of gaseous air pollution with stroke admissions in Beijing, 2013–2014 ...

[Feature] Clear findings, smoggy debate

10-Feb-2017 | David Malakoff, Science , 2017

Proposed rules to cut air pollution regulations often prompt fierce debate, despite decades of studies showing that dirtier air contributes to heart, lung, and other health problems that shorten lives, and that as air gets cleaner, premature deaths decline. The World Health Organization, for ...

IJERPH, Vol. 14, Pages 176: Temporal Trends in Satellite-Derived Erythemal UVB and Implications for Ambient Sun Exposure Assessment

10-Feb-2017 | Langston, Marvin ; Dennis, Leslie ; Lynch, Charles ; Roe, Denise ; Brown, Heidi, International Journal of Environmental Research and Public Health, 2017

Ultraviolet radiation (UVR) has been associated with various health outcomes, including skin cancers, vitamin D insufficiency, and multiple sclerosis. Measurement of UVR has been difficult, traditionally relying on subject recall. We investigated trends in satellite-derived UVB from 1978 to 2014 ...

Human Health and Economic Impacts of Ozone Reductions by Income Group

08-Feb-2017 | Rebecca K. Saari; Tammy M. Thompson; Noelle E. Selin, Environmental Science & Technology, 2017

Low-income households may be disproportionately affected by ozone pollution and ozone policy. We quantify how three factors affect the relative benefits of ozone policies with household income: (1) unequal ozone reductions; (2) policy delay; and (3) economic valuation methods. We model ozone ...

Global long-range transport and lung cancer risk from polycyclic aromatic hydrocarbons shielded by coatings of organic aerosol [Earth, Atmospheric, and Planetary Sciences]

07-Feb-2017 | Manish Shrivastava; Silja Lou; Alla Zelenyuk; Richard C. Easter; Richard A. Corley; Brian D. Thrall; Philip J. Rasch ..., Proceedings of the National Academy of Sciences current issue, 2017

Polycyclic aromatic hydrocarbons (PAHs) have toxic impacts on humans and ecosystems. One of the most carcinogenic PAHs, benzo(a)pyrene (BaP), is efficiently bound to and transported with atmospheric particles. Laboratory measurements show that particle-bound BaP degrades in a few hours by ...

Skeletal Methane–Air Reaction Mechanism for Large Eddy Simulation of Turbulent Microwave-Assisted Combustion

07-Feb-2017 | A. Larsson; N. Zettervall; T. Hurtig; E. J. K. Nilsson; A. Ehn; P. Petersson; M. Alden; J. Larfeldt; C. Fureby, Energy & Fuels, 2017

Irradiating a flame via microwave radiation is a plasma-assisted combustion (PAC) technology that can be used to modify the combustion chemical kinetics in order to improve flame stability and to delay lean blow-out. One practical implication is that combustion engines may be able to operate with ...
