Quantification of volatile organic compounds (VOCs) in environmental air has been recently focused because of their adverse effects on human health, including the so−called multiple chemical sensitivity and sick building syndrome [1,2]. To investigate the effect of VOCs on human health and prevent the above illnesses, a sensitive and reliable method for determining the VOCs in air samples is de...

abstract: mustard is a natural multi-functional additive with strong hot flavor. in this research, powdered yellow mustard (sinapis alba) was heated by 21 different thermal processes, statistically designed by response surface methodology to evaluate the effects of combinations of heating media (hot air, hot water and steam) and heating time (0-20 min) on residual myrosinase activity, the minim...

The aim of this study was to establish whether the air-conditioning system in buses constitutes an additional source of indoor air contamination with fungi, and whether or not the fungi concentration depends on the period from the last disinfection of the system, combined with replacement of the cabin dust particle filter. The air samples to fungi analysis using impact method were taken in 30 b...

BACKGROUND Air pollution has been linked to increased rates of mortality, but little is known about individual characteristics related to the increase in risk. AIMS To examine short term effects of air pollution on daily mortality in elderly people in Bordeaux and compare characteristics of subjects > or =65 years old who died with levels of particulate air pollution. METHODS Daily mortalit...

This system consists of an air cooled low power x-ray tube (50W) with molybdenum anode and a thin (70μm) exit window. An optional beam filter can be inserted to reduce spectral background. The beam is focused onto the sample using a polycapillary x-ray optics, offering a focal spot of about 30μm FWHM. Characteristic X-rays from the sample are detected by means of a Si(Li) detector with ultra th...
