Long-Term Formaldehyde Emissions from Medium-Density Fiberboard in a Full-Scale Experimental Room: Emission Characteristics and the Effects of Temperature and Humidity

21.08.2015 | Weihui Liang; Shen Yang; Xudong Yang, Environmental Science & Technology, 2015

We studied formaldehyde emissions from the medium-density fiberboard (MDF) in a full-scale experimental room to approximate emissions in actual buildings. Detailed indoor formaldehyde concentrations and temperature and humidity data were obtained for about 29 months. Temperature, relative ...

Influence of Temperature, Relative Humidity, and Soil Properties on the Soil–Air Partitioning of Semivolatile Pesticides: Laboratory Measurements and Predictive Models

21.08.2015 | Cleo L. Davie-Martin; Kimberly J. Hageman; Yu-Ping Chin; Valentin Rougé; Yuki Fujita, Environmental Science & Technology, 2015

Soil–air partition coefficient (Ksoil-air) values are often employed to investigate the fate of organic contaminants in soils; however, these values have not been measured for many compounds of interest, including semivolatile current-use pesticides. Moreover, predictive equations for estimating ...

A First Look at the Influence of Anthropogenic Climate Change on the Future Delivery of Fluvial Sediment to the Ganges-Brahmaputra-Meghna Delta

19.08.2015 | Stephen Edward Darby; Frances Eleanor Dunn; Robert J Nicholls; M. Munsur Rahman; Liam Riddy, Journal of Environmental Monitoring, 2015

We employ a climate-driven hydrological water balance and sediment transport model (HydroTrend) to simulate future climate-driven sediment loads flowing into the Ganges-Brahmaputra-Meghna (GBM) mega-delta. The model was parameterised using high-quality topographic data and forced with daily ...

IJERPH, Vol. 12, Pages 9848-9863: Biosurfactant Production by Bacillus salmalaya for Lubricating Oil Solubilization and Biodegradation

19.08.2015 | Dadrasnia, Arezoo ; Ismail, Salmah, International Journal of Environmental Research and Public Health, 2015

This study investigated the capability of a biosurfactant produced by a novel strain of Bacillus salmalaya to enhance the biodegradation rates and bioavailability of organic contaminants. The biosurfactant produced by cultured strain 139SI showed high physicochemical properties and surface ...

Sustainability, Vol. 7, Pages 11098-11113: Seasonal and Diurnal Thermal Performance of a Subtropical Extensive Green Roof: The Impacts of Background Weather Parameters

14.08.2015 | Peng, Lilliana L. H.; Jim, C. Y., Sustainability, 2015

Most studies explored green-roof thermal effects on a few hot summer days based on short-term monitoring data. Few studies investigated the seasonal and diurnal patterns of thermal performance and associated weather effects. This research aims to address the following two questions: (1) how ...

Sustainability, Vol. 7, Pages 11190-11212: Scaled Experimental Study on Maximum Smoke Temperature along Corridors Subject to Room Fires

14.08.2015 | Xing, Zheli ; Mao, Jinfeng ; Huang, Yuliang ; Zhou, Jin ; Mao, Wei ; Deng, Feifan, Sustainability, 2015

In room–corridor building geometry, the corridor smoke temperature is of great importance to fire protection engineering as indoor fires occur. Theoretical analysis and a set of reduced-scale model experiments were performed, and a virtual fire model was proposed, to investigate the correlations ...

Char‐supported Fe–Zn–Cu sorbent prepared by ultrasonic‐assisted impregnation for simultaneous removal of H2S and COS from coke oven gas

13.08.2015 | Jinxiao Dou, Arash Tahmasebi, Xianchun Li, Fengkui Yin, Jianglong Yu, Environmental Progress, 2015

Lignite char supported Fe–Zn–Cu sorbents were prepared by ultrasonic‐assisted impregnation method for the simultaneous removal of H2S and COS from coke oven gas (COG). Sulfidation experiments were carried out in a fixed‐bed quartz reactor using simulated COG. The results showed that the addition ...

Contribution of Liquid/Gas Mass-Transfer Limitations to Dissolved Methane Oversaturation in Anaerobic Treatment of Dilute Wastewater

13.08.2015 | Hyeongu Yeo; Junyeong An; Robertson Reid; Bruce E. Rittmann; Hyung-Sool Lee, Environmental Science & Technology, 2015

The mechanisms controlling the accumulation of dissolved methane in anaerobic membrane bioreactors (AnMBRs) treating a synthetic dilute wastewater (a glucose medium) were assessed experimentally and theoretically. The AnMBR was maintained at a temperature of 24–26 °C as the organic loading rate ...

Atmospheric Feedback of Urban Boundary Layer with Implications for Climate Adaptation

12.08.2015 | Marissa S. Liang; Timothy C. Keener, Environmental Science & Technology, 2015

Atmospheric structure changes in response to the urban form, land use, and the type of land cover (LULC). This interaction controls thermal and air pollutant transport and distribution. The interrelationships among LULC, ambient temperature, and air quality were analyzed and found to be ...

IJERPH, Vol. 12, Pages 9357-9374: Factors Contributing to Hypoxia in the Minjiang River Estuary, Southeast China

11.08.2015 | Zhang, Peng ; Pang, Yong ; Pan, Hongche ; Shi, Chengchun ; Huang, Yawen ; Wang, Jianjian, International Journal of Environmental Research and Public Health, 2015

Dissolved oxygen (DO) is not only a fundamental parameter of coastal water quality, but also an indication of organics decomposed in water and their degree of eutrophication. There has been a concern about the deterioration of dissolved oxygen conditions in the Minjiang River Estuary, the longest ...
