IJERPH, Vol. 13, Pages 1200: Indoor Air Quality in the Metro System in North Taiwan

02-Dec-2016 | Chen, Ying-Yi ; Sung, Fung-Chang ; Chen, Mei-Lien ; Mao, I-Fang ; Lu, Chung-Yen, International Journal of Environmental Research and Public Health, 2016

Indoor air pollution is an increasing health concern, especially in enclosed environments such as underground subway stations because of increased global usage by urban populations. This study measured the indoor air quality of underground platforms at 10 metro stations of the Taipei Rapid ...

Role of Initial Precursor Chemisorption on Incubation Delay for Molybdenum Oxide Atomic Layer Deposition

30-Nov-2016 | Charith E. Nanayakkara; Abraham Vega; Guo Liu; Charles L. Dezelah; Ravindra K. Kanjolia; Yves J. Chabal, Chemistry of Materials, 2016

In an effort to grow metal oxide films (e.g., MoO3) at low temperatures, a novel molybdenum precursor, Si(CH3)3CpMo(CO)2(η3-2-methylallyl) or MOTSMA, is used with ozone as the coreactant. As is often observed in atomic layer deposition (ALD) processes, the deposition of molybdenum trioxide ...

Relative Importance of Different Water Categories as Sources of N-Nitrosamine Precursors

29-Nov-2016 | Teng Zeng; Caitlin M. Glover; Erica J. Marti; Gwen C. Woods-Chabane; Tanju Karanfil; William A. Mitch; Eric R. V. Di ..., Environmental Science & Technology, 2016

A comparison of loadings of N-nitrosamines and their precursors from different source water categories is needed to design effective source water blending strategies. Previous research using Formation Potential (FP) chloramination protocols (high dose and prolonged contact times) raised concerns ...

IJMS, Vol. 17, Pages 1964: Elevated O3 and TYLCV Infection Reduce the Suitability of Tomato as a Host for the Whitefly Bemisia tabaci

28-Nov-2016 | Cui, Hongying ; Sun, Yucheng ; Chen, Fajun ; Zhang, Youjun ; Ge, Feng, International Journal of Molecular Sciences, 2016

The effects of elevated atmospheric ozone (O3) levels on herbivorous insects have been well studied, but little is known about the combined effects of elevated O3 and virus infection on herbivorous insect performance. Using open-top chambers in the field, we determined the effects of elevated O3 ...

[Editors' Choice] No silver bullet for wastewater treatment

18-Nov-2016 | Julia Fahrenkamp-Uppenbrink, Science , 2016

Antibiotic Resistance The spread of antibiotic resistance is a major public health concern. Czekalski et al. investigate whether ozonation of wastewater can help to combat this spread by eliminating resistant bacteria. In laboratory experiments, ozone doses that can be used in full-scale

Evaluation of antibacterial and antifungal compounds for selective inhibition of denitrification in soils

17-Nov-2016 | Shiva Ladan; Pierre-André Jacinthe, Journal of Environmental Monitoring, 2016

Nitrous oxide (N2O) is an atmospheric constituent implicated in climate warming and stratospheric ozone depletion. Both bacteria and fungi participate in N2O production, but information is lacking with regard to the relative contribution of bacterial and fungal denitrifiers to the denitrification ...

Constraints on Arctic Atmospheric Chlorine Production through Measurements and Simulations of Cl2 and ClO

07-Nov-2016 | Kyle D. Custard; Kerri A. Pratt; Siyuan Wang; Paul B. Shepson, Environmental Science & Technology, 2016

During springtime, unique halogen chemistry involving chlorine and bromine atoms controls the prevalence of volatile organic compounds, ozone, and mercury in the Arctic lower troposphere. In situ measurements of the chlorine monoxide radical, ClO, and its precursor, Cl2, along with BrO and Br2, ...

IJERPH, Vol. 13, Pages 1074: Proposal of Environmental Impact Assessment Method for Concrete in South Korea: An Application in LCA (Life Cycle Assessment)

02-Nov-2016 | Kim, Tae Hyoung; Tae, Sung Ho, International Journal of Environmental Research and Public Health, 2016

This study aims to develop a system for assessing the impact of the substances discharged from concrete production process on six environmental impact categories, i.e., global warming (GWP), acidification (AP), eutrophication (EP), abiotic depletion (ADP), ozone depletion (ODP), and photochemical ...

A theoretical study of the atmospherically important radical-radical reaction BrO + HO2; the product channel O2(a1g) + HOBr is formed with the highest rate.

26-Oct-2016 | John M DYKE; Edmond Pak Fai Lee; Daniel K.W. Mok; Ronald Chow, Physical Chemistry Chemical Physics, 2016

A theoretical study has been made of the BrO + HO2 reaction, a reaction which contributes to ozone depletion in the atmosphere via production of HOBr. Enthalpies, activation energies and mechanisms have been determined for five reaction channels. Also rate coefficients have been calculated for ...
