Determination of volatile hydrocarbons in air; Bestaemning av flyktiga kolvaeten i luft

Abstract

Environmentally important hydrocarbons in air were determined by sampling on selected adsorbents followed by thermal desorption and gas chromatography on suitable columns in the laboratory. The carcinogenic 1.3-butadiene and the four isomeric butenes were determined in the complex hydrocarbon mixture of petrol exhaust and petrol vapour in urban air. The concentration of butadiene, reflecting outdoor urban exposure, was in the range of 0.5-5 {mu}g/m{sup 3}. Exposure levels of a suburban motorist was assessed for more than twenty volatile aromatic hydrocarbons from traffic exhaust. The levels were found to be 5-10 times higher than those of a train commuter. Comparisons in Switzerland and Sweden with differential optical absorption spectroscopy (DOAS) demonstrated this recently developed technique to be useful for continuous monitoring of benzene and toluene (above 10 {mu}g/m{sup 3}) in moderately to heavily polluted urban air. The diffuse hydrocarbon emissions from the process area of a bitumen refinery were determined from vertical and horizontal concentration profiles across the emission plume. The sum of the C{sub 8}-C{sub 9} hydrocarbons made up 40% and the aromatic hydrocarbons made up 20% of the plume
