Purpose-made capillary electrophoresis instruments coupled with contactless conductivity detection as a simple and inexpensive solution for water analysis: a case study in Vietnam

30-Sep-2015 | Hong Anh Duong; Minh Duc Le; Diem Mai Kim Nguyen; Peter C Hauser; Pham Hung Viet; Duc Thanh Mai, Journal of Environmental Monitoring, 2015

A simple and inexpensive method for determination of various ionic species in different water matrices is discussed in this study. The approach is based on the employment of purpose-made capillary electrophoresis (CE) instruments with capacitively coupled contactless conductivity detection (C4D), ...


Sustainability, Vol. 7, Pages 13290-13316: Sustainable Cities and the Contribution of Historical Urban Green Spaces: A Case Study of Historical Persian Gardens

29-Sep-2015 | Rostami, Raheleh ; Lamit, Hasanuddin ; Khoshnava, Seyed Meysam; Rostami, Rasoul ; Rosley, Muhamad Solehin Fitry, Sustainability, 2015

Growing populations and rapid worldwide urbanization are recognized as constituting one of the most complex processes in the world and have raised concerns about the sustainability of cities. Sustainable development, a widely accepted strategic framework in city planning, singles out urban green ...


Scaling-Free Electrochemical Production of Caustic and Oxygen for Sulfide Control in Sewers

24-Sep-2015 | Hui-Wen Lin; Korneel Rabaey; Jürg Keller; Zhiguo Yuan; Ilje Pikaar, Environmental Science & Technology, 2015

Caustic shock-loading and oxygen injection are commonly used by the water industry for biofilm and sulfide control in sewers. Caustic can be produced onsite from wastewater using a two-compartment electrochemical cell. This avoids the need for import and storage of caustic soda, which typically ...


Sustainability, Vol. 7, Pages 12856-12869: Evaluation of the Effects of Mitigation on Methane and Ammonia Production by Using Origanum vulgare L. and Rosmarinus officinalis L. Essential Oils on in Vitro Rumen Fermentation Systems

18-Sep-2015 | Cobellis, Gabriella ; Petrozzi, Alessandro ; Forte, Claudio ; Acuti, Gabriele ; Orrù, Mara ; Marcotullio, Maria Carl ..., Sustainability, 2015

The effects of increasing concentrations of oregano (Origanum vulgare L.) and rosemary (Rosmarinus officinalis L.) essentials oil (EO) on ruminal gas emissions were tested in vitro using 50 mL serum bottles. Each bottle contained a 200 mg substrate (alfalfa hay and corn meal 1:1) and a 20 mL ...


Sustainability, Vol. 7, Pages 12615-12633: Selecting Eco-Friendly Thermal Systems for the “Vittoriale Degli Italiani” Historic Museum Building

15-Sep-2015 | Garcia, Davide Astiaso; Di Matteo, Umberto ; Cumo, Fabrizio, Sustainability, 2015

Thermal systems installed in museums should guarantee the maintenance of the optimal hygrothermal parameters ranges for the conservation of their collection materials. Considering the preservation of historic buildings, according to their historical and landscaping constraints, not all the ...


Fractionation of Selenium during Selenate Reduction by Granular Zerovalent Iron

15-Sep-2015 | Heather K. Shrimpton; David W. Blowes; Carol J. Ptacek, Environmental Science & Technology, 2015

Batch experiments were conducted using granular zerovalent iron (G-ZVI) with either ultrapure water or CaCO3 saturated simulated groundwater to assess the extent of Se isotope fractionation in solution under the anaerobic conditions characteristic of many aquifers. G-ZVI is a common remediation ...


Sustainability, Vol. 7, Pages 12490-12501: Soil Degradation: Will Humankind Ever Learn?

11-Sep-2015 | Karlen, Douglas L.; Rice, Charles W., Sustainability, 2015

Soil degradation is a global problem caused by many factors including excessive tillage, inappropriate crop rotations, excessive grazing or crop residue removal, deforestation, mining, construction and urban sprawl. To meet the needs of an expanding global population, it is essential for ...


Facilitated Leaching of Additive-Derived PBDEs from Plastic by Seabirds’ Stomach Oil and Accumulation in Tissues

10-Sep-2015 | Kosuke Tanaka; Hideshige Takada; Rei Yamashita; Kaoruko Mizukawa; Masa-aki Fukuwaka; Yutaka Watanuki, Environmental Science & Technology, 2015

Our previous study suggested the transfer of polybrominated diphenyl ether (PBDE) flame retardants from ingested plastics to seabirds’ tissues. To understand how the PBDEs are transferred, we studied leaching from plastics into digestive fluids. We hypothesized that stomach oil, which is present ...


Biostimulation by Glycerol Phosphate to Precipitate Recalcitrant Uranium(IV) Phosphate

02-Sep-2015 | Laura Newsome; Katherine Morris; Divyesh Trivedi; Alastair Bewsher; Jonathan R Lloyd, Environmental Science & Technology, 2015

Stimulating the microbial reduction of aqueous uranium(VI) to insoluble U(IV) via electron donor addition has been proposed as a strategy to remediate uranium-contaminated groundwater in situ. However, concerns have been raised regarding the longevity of microbially precipitated U(IV) in the ...


Activated carbons prepared from Thymelaea hirsuta wood: Sustainable adsorbents for polyvinyl alcohol

01-Sep-2015 | Abdessalem Omri, Mourad Benzina, Environmental Progress, 2015

In this study, activated carbon as novel adsorbent was prepared from low cost and locally available source such as Thymelaea hirsuta wood. Characterization of the adsorbent was carried out and BET surface area of the adsorbent was found to be 1496 m2/g. Subsequently, the Thymelaea hirsuta wood ...
