The concentration of volatile organic compounds (VOCs) and related factors in the air in barbershops in Sanandaj in 2016
The aim of this study was to determine the density of benzene and toluene in barbershops of Sanandaj and also to determine effective factors for this pollution. A descriptive, analytical study was conducted to measure the volatile organic compound density and determine the effective factors. In this study, five hair salons and five barber shops were randomly selected from Sanandaj city. The vol...
متن کاملThe concentration of volatile organic compounds (VOCs) in pig farm air.
The aim of the study was to assess the level of air pollution by volatile organic compounds (VOCs) in a pig fattening house and in its vicinity. Air samples for chromatographic analysis were taken in the fattening house and in the vicinity of the farm. The air quality study shows that the level of organic gaseous pollutants was twice as high in the fattening house as in the atmospheric air. Alm...
متن کاملAre Some Fungal Volatile Organic Compounds (VOCs) Mycotoxins?
Volatile organic compounds (VOCs) are carbon-compounds that easily evaporate at room temperature. Toxins are biologically produced poisons; mycotoxins are those toxins produced by microscopic fungi. All fungi emit blends of VOCs; the qualitative and quantitative composition of these volatile blends varies with the species of fungus and the environmental situation in which the fungus is grown. T...

متن کاملA two-column method for long-term monitoring of non-methane hydrocarbons (NMHCs) and oxygenated volatile organic compounds (o-VOCs).
A method has been developed for concurrent analysis of C2-C7 hydrocarbons and C2-C5 oxygenated volatile organic compounds (o-VOCs) including alcohols, aldehydes, ketones and ethers. A multi-bed, Peltier-cooled adsorbent trap, consisting of Carboxen 1000 and Carbopack B, was used to acquire one sample per hour. Upon injection the sample was split in an approximately 50:50 ratio between a 50 m al...
