Ambient hydrocarbons from motor-car assembly plants in Scandinavia

• About 50 air-polluting hydrocarbons were determined in emissions from the Volvo and Saab motor-car plants. The sampling technique used was based on the Tenax GC adsorbent. Thermal desorption and glass capillary gas chromatography was used for the analysis. At a downwind distance of about 1 km, concentrations about 100 times higher than regional levels were recorded. The emissions constitute potential ecological and health hazards and a reduction of quantities and complexity is urgent.
