IJERPH, Vol. 11, Pages 11627-11644: Association of Weekly Suicide Rates with Temperature Anomalies in Two Different Climate Types

13.11.2014 | Dixon, P. Grady; Sinyor, Mark ; Schaffer, Ayal ; Levitt, Anthony ; Haney, Christa R.; Ellis, Kelsey N.; Sheridan, Sc ..., International Journal of Environmental Research and Public Health, 2014

Annual suicide deaths outnumber the total deaths from homicide and war combined. Suicide is a complex behavioral endpoint, and a simple cause-and-effect model seems highly unlikely, but relationships with weather could yield important insight into the biopsychosocial mechanisms involved in ...

Number and Size Distribution of Airborne Nanoparticles during Summertime in Kuwait: First Observations from the Middle East

13.11.2014 | Abdullah N. Al-Dabbous; Prashant Kumar, Environmental Science & Technology, 2014

We made fast response measurements of size-resolved particle number concentrations (PNCs) and distributions (PNDs) in the 5–1000 nm range close to a busy roadside, continuously for 31 days, in Kuwait. The aims were to understand their dispersion characteristics during summertime and dust events, ...

IJERPH, Vol. 11, Pages 11616-11626: Influence of Daily Individual Meteorological Parameters on the Incidence of Acute Coronary Syndrome

12.11.2014 | Ravljen, Mirjam ; Bilban, Marjan ; Kajfež-Bogataj, Lučka ; Hovelja, Tomaž ; Vavpotič, Damjan, International Journal of Environmental Research and Public Health, 2014

Background: A nationwide study was conducted to explore the short term association between daily individual meteorological parameters and the incidence of acute coronary syndrome (ACS) treated with coronary emergency catheter interventions in the Republic of Slovenia, a south-central European ...

IJERPH, Vol. 11, Pages 11481-11504: Modeling Spatial and Temporal Variability of Residential Air Exchange Rates for the Near-Road Exposures and Effects of Urban Air Pollutants Study (NEXUS)

07.11.2014 | Breen, Michael S.; Burke, Janet M.; Batterman, Stuart A.; Vette, Alan F.; Godwin, Christopher ; Croghan, Carry W.; S ..., International Journal of Environmental Research and Public Health, 2014

Air pollution health studies often use outdoor concentrations as exposure surrogates. Failure to account for variability of residential infiltration of outdoor pollutants can induce exposure errors and lead to bias and incorrect confidence intervals in health effect estimates. The residential air ...

IJERPH, Vol. 11, Pages 11421-11437: Multivariate Optimization for Extraction of Pyrethroids in Milk and Validation for GC-ECD and CG-MS/MS Analysis

05.11.2014 | Meneghini, Leonardo Zanchetti; Rübensam, Gabriel ; Bica, Vinicius Claudino; Ceccon, Amanda ; Barreto, Fabiano ; Ferr ..., International Journal of Environmental Research and Public Health, 2014

A simple and inexpensive method based on solvent extraction followed by low temperature clean-up was applied for determination of seven pyrethroids residues in bovine raw milk using gas chromatography coupled to tandem mass spectrometry (GC-MS/MS) and gas chromatography with electron-capture ...

Biofouling and Microbial Communities in Membrane Distillation and Reverse Osmosis

31.10.2014 | Katherine R. Zodrow; Edo Bar-Zeev; Michael J. Giannetto; Menachem Elimelech, Environmental Science & Technology, 2014

Membrane distillation (MD) is an emerging desalination technology that uses low-grade heat to drive water vapor across a microporous hydrophobic membrane. Currently, little is known about the biofilms that grow on MD membranes. In this study, we use estuarine water collected from Long Island ...

Investigation into the dehydration process of oily sludge by fry‐drying method

27.10.2014 | Ke Zhang, Jianhua Zhu, Yong Zhou, Bencheng Wu, Environmental Progress, 2014

This study investigated the oily sludge water loss and oil uptake phenomenon during the fry‐drying process. A cylindrical sample of oily sludge was added to the preheated spent lubricating oil of vehicle. A diffusion model and a first‐order kinetic model were proposed to predict the water and ...

Novel Microelectrode-Based Online System for Monitoring N2O Gas Emissions during Wastewater Treatment

23.10.2014 | Ricardo Marques; Adrian Oehmen; Maite Pijuan, Environmental Science & Technology, 2014

Clark-type nitrous oxide (N2O) microelectrodes are commonly used for measuring dissolved N2O levels, but have not previously been tested for gas-phase applications, where the N2O emitted from wastewater systems can be directly quantified. In this study, N2O microelectrodes were tested and ...

Sustainability, Vol. 6, Pages 7263-7275: Wireless Sensor Network Powered by a Terrestrial Microbial Fuel Cell as a Sustainable Land Monitoring Energy System

22.10.2014 | Pietrelli, Andrea ; Micangeli, Andrea ; Ferrara, Vincenzo ; Raffi, Alessandro, Sustainability, 2014

This work aims at investigating the possibility of a wireless sensor network powered by an energy harvesting technology, such as a microbial fuel cell (MFC). An MFC is a bioreactor that transforms energy stored in chemical bonds of organic compounds into electrical energy. This process takes ...

Warming Influences Mg2+ Content, While Warming and Acidification Influence Calcification and Test Strength of a Sea Urchin

17.10.2014 | Maria Byrne; Abigail M. Smith; Samantha West; Marie Collard; Philippe Dubois; Alexia Graba-landry; Symon A Dworjanyn, Environmental Science & Technology, 2014

We examined the long-term effects of near-future changes in temperature and acidification on skeletal mineralogy, thickness, and strength in the sea urchin Tripneustes gratilla reared in all combinations of three pH (pH 8.1, 7.8, 7.6) and three temperatures (22 °C, 25 °C, 28 °C) from the early ...
