スウェーデンにおける排気ガス中及び空気中の低沸点芳香族炭化水素類

Recent studies on volatile aromatic hydrocarbons in exhaust and air from Sweden are intro-duced. The aromatic hydrocarbons which were focused on here are benzene, toluene, ethylben-zene and xylenes (BTEXs) . Proportions (percentile weight) of BTEXs in exhaust from domestic wood burning, a cat-cracking refinery and vehicles are reported. Concentrations of BTEXs are studied on indoor and outdoor air. These results are very important for evaluating impact of the BTEXs on atmospheric environment and human health by inhalation.
