Oxidative Degradation of Decabromodiphenyl Ether (BDE 209) by Potassium Permanganate: Reaction Pathways, Kinetics, and Mechanisms Assisted by Density Functional Theory Calculations

13.03.2015 | Jiaqi Shi; Ruijuan Qu; Mingbao Feng; Xinghao Wang; Liansheng Wang; Shaogui Yang; Zunyao Wang, Environmental Science & Technology, 2015

This study found that decabromodiphenyl ether (BDE 209) could be oxidized effectively by potassium permanganate (KMnO4) in sulfuric acid medium. A total of 15 intermediate oxidative products were detected. The reaction pathways were proposed, which primarily included cleavage of the ether bond to ...

In-situ tryptophan-like fluorometers: assessing turbidity and temperature effects for freshwater applications

11.03.2015 | Kieran Khamis; James Sorensen; Chris Bradley; David Hannah; Daniel J Lapworth; Robert Stevens, Journal of Environmental Monitoring, 2015

Tryptophan-like fluorescence (TLF) is an indicator of human influence on water quality as TLF peaks are associated with the input of labile organic carbon (e.g. sewage or farm waste) and its microbial breakdown. Hence, real-time measurement of TLF could be particularly useful for monitoring water ...

Sustainability, Vol. 7, Pages 2858-2870: Effects of Weather Variability on Crop Abandonment

09.03.2015 | Mulungu, Kelvin ; Tembo, Gelson, Sustainability, 2015

In Zambia, every year some parts of the maize fields are abandoned post-planting. Reasons for this are not clearly known. In this paper, we examine the influence of soil and climatic factors on crop abandonment using a six-year (2007–2012) panel data by modeling the planted-to-harvested ratio (a ...

Sustainability, Vol. 7, Pages 2804-2817: Study on the Thermal Effects and Air Quality Improvement of Green Roof

06.03.2015 | Luo, Heng ; Wang, Ning ; Chen, Jianping ; Ye, Xiaoyan ; Sun, Yun-Fei, Sustainability, 2015

Heat island phenomenon and air quality deterioration issues are two major problems that have occurred during the process of urbanization, especially in developing countries. A number of measures have been proposed, among which roof greening is considered as a promising one due to its outstanding ...

Sustainability, Vol. 7, Pages 2644-2661: Estimating Solar Irradiation Absorbed by Photovoltaic Panels with Low Concentration Located in Craiova, Romania

04.03.2015 | Alboteanu, Ionel L.; Bulucea, Cornelia A.; Degeratu, Sonia, Sustainability, 2015

Solar irradiation is one of the important parameters that should be taken into consideration for the design and utilization of a photovoltaic system. Usually, the input parameters of a photovoltaic system are solar irradiation, the ambient environment temperature and the wind speed, and as a ...

IJERPH, Vol. 12, Pages 2765-2780: Association of PNC, BC, and PM2.5 Measured at a Central Monitoring Site with Blood Pressure in a Predominantly Near Highway Population

03.03.2015 | Chung, Mei ; Wang, Ding Ding; Rizzo, Amanda M.; Gachette, Darrel ; Delnord, Marie ; Parambi, Ron ; Kang, Choong-Min ..., International Journal of Environmental Research and Public Health, 2015

Elevated blood pressure is an indicator of cardiovascular stress and increased risk of cardiovascular-related morbidity and mortality. There is emerging evidence suggesting air pollutants, including particulate matter (PM), could promote hypertension, thereby increasing cardiovascular disease ...

IJERPH, Vol. 12, Pages 2735-2748: Temperature Variation and Heat Wave and Cold Spell Impacts on Years of Life Lost Among the Urban Poor Population of Nairobi, Kenya

02.03.2015 | Egondi, Thaddaeus ; Kyobutungi, Catherine ; Rocklöv, Joacim, International Journal of Environmental Research and Public Health, 2015

Weather extremes are associated with adverse health outcomes, including mortality. Studies have investigated the mortality risk of temperature in terms of excess mortality, however, this risk estimate may not be appealing to policy makers assessing the benefits expected for any interventions to ...

IJERPH, Vol. 12, Pages 2543-2556: Salmonella and Eggs: From Production to Plate

26.02.2015 | Whiley, Harriet ; Ross, Kirstin, International Journal of Environmental Research and Public Health, 2015

Salmonella contamination of eggs and egg shells has been identified as a public health concern worldwide. A recent shift in consumer preferences has impacted on the egg industry, with a push for cage-free egg production methods. There has also been an increased desire from consumers for raw and ...
