OBJECTIVE To examine the effect on hospital presentations for asthma of brief exposures to sulphur dioxide (SO2) (within the range 0-8700 micrograms/m3) emanating from two point sources in a remote rural city of 25,000 people. METHODS A time series analysis of SO2 concentrations and hospital presentations for asthma was undertaken at Mount Isa where SO2 is released into the atmosphere by a co...

This work examines the process of detecting and quantifying volcanic SO2 plumes using the Airborne Hyperspectral Infrared Imager (AHI) developed by the University of Hawaii. AHI was flown over Pu'u'O'o Vent of Kilauea Volcano in Hawaii to collect data on SO2 plumes. AHI is a LWIR pushbroom imager sensitive to the 7.5 11.5 μ region. Spectral analysis and mapping tools were used to identify and c...

SO2emissions, the largest sourceof anthropogenic aerosols, can respond rapidly toeconomic and policy driven changes. However, bottom-up SO2 inventories have inherent limitations owing to 24–48months latency and lack of month-to-month variation in emissions (especially in developing countries). This study develops a new approach that integrates OzoneMonitoring Instrument (OMI) SO2 satellitemeasu...

Abstract With modern genetic engineering tools, microorganisms can become resilient green cell factories to produce sustainable biofuels directly. Compared non-engineered algae and cyanobacteria, the photon conversion efficiency be significantly increased. Furthermore, simplified harvesting processes are feasible since novel excreting or their precursors continuously directly into cultivation m...

Abstract The production of flat steel products is commonly linked to highly integrated sites, which include hot metal generation via the blast furnace, basic oxygen furnace (BOF), continuous casting, and subsequent hot-rolling. In order reach carbon neutrality a shift away from traditional carbon-based metallurgy required within next decades. Direct reduction (DR) plants are capable support thi...

in this research, the energy flow and production energy indices of canola cultivation in trakya province of turkey, golestan and mazandaran provinces of iran were compared. diesel fuel and chemical fertilizer inputs were the highest consumer of energy in the production of canola in these three regions. the results indicated that despite the higher energy use of machinery in trakya province of t...

Carbon-enriched coal fly ash was evaluated in this work as a low-cost adsorbent for SO2 removal from stack gases. The unburned carbon in coal fly ash was concentrated by mechanical sieving and vegetal oil agglomeration. The carbon concentrates were activated with steam at 900 degrees C in order to develop porosity onto the samples. The performance of these samples in the SO2 abatement was teste...

Greenhouse gas (GHG) emissions related to recycling of glass waste were assessed from a waste management perspective. Focus was on the material recovery facility (MRF) where the initial sorting of glass waste takes place. The MRF delivers products like cullet and whole bottles to other industries. Two possible uses of reprocessed glass waste were considered: (i) remelting of cullet added to gla...

Rationale and objective Improving diet quality while decreasing environmental impacts is an important challenge for a healthy sustainable food system. Therefore, this study aims to analyze the most common dietary patterns per female household member explore of these patterns. Methodology The nationally representative General Nutrition Survey 2009–2010 ( n = 8,225 households) was used derive usi...
