The objective of this study was to demonstrate the methodological shortcomings of currently available analytical methods for single-city time series data. We analyzed daily Chronic Obstructive Pulmonary Disease (COPD) and daily asthma hospital admissions in Melbourne, Australia from July 1989 to December 1992. Air pollution data comprised nitrogen dioxide, ozone and sulphur dioxide and air part...

• Polluted indoor air can lead to discomfort, reduced efficiency and even ill health amongst employees and residents in modern buildings. • Wool carpet has been shown to rapidly neutralize formaldehyde, nitrogen dioxide and sulphur dioxide, common contaminants in today's indoor environment. • Not only does wool neutralize these contaminants more quickly and completely than synthetic carpet fibe...

The relation between mortality of people aged 45 to 74 and atmospheric smoke and sulphur dioxide in the county and London boroughs of England and Wales was investigated using data for the years 1969 to 1973. Weighted multiple regression analyses, which took into account a number of socioeconomic and climatic variables, showed no consistent relation of smoke or sulphur dioxide with mortality fro...

* Correspondence: [email protected] 1. Brief historical notes and discovery of cadmium Friedrich Stromeyer and Karl Hermann discovered cadmium (Cd) almost simultaneously in 1817 in samples of zinc oxide obtained by roasting zinc carbonate from Salzgitter (Germany). Cd has no amphoteric properties and, although cadmiate anions are found, it does not dissolve in bases (Borsari, 2011). Cd is a ...

Co-combustion of biosolids with coal or other biomass fuel can play a significant role in combustion facilities for energy production and waste management policy context. This paper presents the results of an experimental study to investigate the use of biosolids for co-combustion with wood pellets in a wood pellet stove. Fuel property, gas emissions and stove efficiency are compared. In regard...

The addition of molecular iodine to solutions of te rtiary aliphatic amines in liquid sulphur dioxide is found to result in the formation of stable free radical oxidation in te r­ mediates. In triethylam ine solutions, oxidised under these conditions, arom atisation appears to take place to produce a pyridinyl radical. Radicals formed from N-ethyldim ethylam ine, N ,N -diethylm ethylam ine and ...

Quinones are central intermediates in wine oxidation that can degrade the quality of wine by reactions with varietal thiols, such as 3-sulfanylhexanol, decreasing desirable aroma. Protection by wine preservatives (sulphur dioxide, glutathione, ascorbic acid and model tannin, phloroglucinol) was assessed by competitive sacrificial reactions with 4-methyl-1,2-benzoquinone, quantifying products an...
