Consequences of stratospheric ozone depletion and climate change on the use of materials

18-11-2014 | A. L. Andrady; A. Torikai; H. H. Redhwi; K. K. Pandey; P. Gies, Photochemical & Photobiological Sciences, 2014

Materials used in the exterior of buildings and in construction are routinely exposed to solar UV radiation. Especially in the case of wood and plastic building materials, the service life is determined by their weather-induced deterioration. Any further increase in ground-level solar UV ...

The consequences for human health of stratospheric ozone depletion in association with other environmental factors

18-11-2014 | R. M. Lucas; M. Norval; R. E. Neale; A. R. Young; F. R. de Gruijl; Y. Takizawa; J. C. van der Leun, Photochemical & Photobiological Sciences, 2014

Due to the implementation of the Montreal Protocol, which has limited, and is now probably reversing, the depletion of the stratospheric ozone layer, only modest increases in solar UV-B radiation at the surface of the Earth have occurred. For many fair-skinned populations, changing behaviour with ...

Treatment of gaseous effluents by using surface discharge plasma in continuous reactors: Process modeling and simulation

12-11-2014 | Assadi Aymen Amine, Bouzaza Abdelkrim, Wolbert Dominique, The Canadian Journal of Chemical Engineering, 2014

Abstract In the present work, the oxidation of isovaleraldehyde, a typical pollutant of indoor air, is investigated by using two different plasma DBD reactors: cylindrical and planar reactor. The study of the influence of the specific energy shows that its increment is accompanied by an ...

Ozone depletion and climate change: impacts on UV radiation

12-11-2014 | A. F. Bais; R. L. McKenzie; G. Bernhard; P. J. Aucamp; M. Ilyas; S. Madronich; K. Tourpali, Photochemical & Photobiological Sciences, 2014

We assess the importance of factors that determine the intensity of UV radiation at the Earth's surface. Among these, atmospheric ozone, which absorbs UV radiation, is of considerable importance, but other constituents of the atmosphere, as well as certain consequences of climate change, can also ...

Effects of stratospheric ozone depletion, solar UV radiation, and climate change on biogeochemical cycling: interactions and feedbacks

12-11-2014 | David J. Erickson III; Barbara Sulzberger; Richard G. Zepp; Amy T. Austin, Photochemical & Photobiological Sciences, 2014

Climate change modulates the effects of solar UV radiation on biogeochemical cycles in terrestrial and aquatic ecosystems, particularly for carbon cycling, resulting in UV-mediated positive or negative feedbacks on climate. Possible positive feedbacks discussed in this assessment include: (i) ...

Changes in air quality and tropospheric composition due to depletion of stratospheric ozone and interactions with changing climate: implications for human and environmental health

11-11-2014 | S. Madronich; M. Shao; S. R. Wilson; K. R. Solomon; J. D. Longstreth; X. Y. Tang, Photochemical & Photobiological Sciences, 2014

UV radiation is an essential driver for the formation of photochemical smog, which includes ground-level ozone and particulate matter (PM). Recent analyses support earlier work showing that poor outdoor air quality is a major environmental hazard as well as quantifying health effects on regional ...

Ozone Effect on Fungi Proliferation and Genera Susceptibility of Treated Stored Dry Paddy Rice (Oryza sativa L.)

06-11-2014 | Menithen Beber‐Rodrigues, Geovana D. Savi, Vildes M. Scussel, Journal of Food Safety, 2014

Abstract This work reports the ozone (O3) gas effects on stored dry paddy rice (Oryza sativa L.) mycoflora (fungi reduction/genera susceptibility/yeast) and humidity microorganism proliferation factors (moisture content [mc]/water activity [aw]. From the three O3 concentrations applied (10, ...

Effect of ozone treatment on physicochemical properties of waxy rice flour and waxy rice starch

05-11-2014 | Wenping Ding, Yuehui Wang, Wei Zhang, Yongcheng Shi, Donghai Wang, International Journal of Food Science & Technology, 2014

Summary The effect of ozone treatment on physicochemical properties of waxy rice flour and waxy rice starch was investigated. Results showed that ozone treatment increased the pasting viscosity of waxy rice flour. Compared with untreated waxy rice flour, the peak viscosities of waxy rice flour ...

Tailored design of boron‐doped diamond electrodes for various electrochemical applications with boron‐doping level and sp2‐bonded carbon impurities

31-10-2014 | Takeshi Watanabe, Yuki Honda, Kazuhiro Kanda, Yasuaki Einaga, physica status solidi (a), 2014

Abstract The effects of sp2‐bonded carbon impurities on the electrochemical properties of boron‐doped diamond were investigated in moderately ([B] 20 cm−3) and heavily ([B] > 1021 cm−3) boron doping levels. Significant influences of sp2‐bonded carbon impurities, which show glassy carbon‐like ...

Ozone-initiated Terpene Reaction Products in Five European Offices: Replacement of a Floor Cleaning Agent

31-10-2014 | A.W. Nørgaard; V. Kofoed-Sørensen; C. Mandin; G. Ventura; R. Mabilia; E. Perreca; A. Cattaneo; A. Spinazzè; V.G. Mih ..., Environmental Science & Technology, 2014

Cleaning agents often emit terpenes that react rapidly with ozone. These ozone-initiated reactions, which occur in the gas-phase and on surfaces, produce a host of gaseous and particulate oxygenated compounds with possible adverse health effects in the eyes and airways. Within the European Union ...
