CO EMISSIONS FROM PASSENGER CARS ON HIGH MOUNTAIN ROADS

CO-EMISSION VON PERSONENKRAFTWAGEN AUF HOCHGEBIRGSSTRASSEN

MEASUREMENTS TAKEN ON THE GROSSGLOCKNER HIGH ALPINE ROAD PROVED THE MARKED EFFECT OF HEIGHT ABOVE SEA LEVEL ON EXHAUST EMISSIONS FROM PASSENGER CARS WITH PETROL ENGINES. STUDIES HAVE SHOWN THAT THE FLOW OF POLLUTED AIR FROM THE ROAD FOLLOWS THE RELIEF ON THE LANDSCAPE AND OFTEN LEADS TO DAMAGE TO THE VEGETATION. SO FAR THE PRODUCTION OF EXHAUST FUMES AND HARMFUL EMISSIONS FROM VARIOUS TYPES OF MOTOR VEHICLES IN CERTAIN AREAS OF THE HIGH MOUNTAIN ROADS IS NOT KNOWN, NOR IS THE EXPECTED AIR POLLUTION IN THE REGION OF THE VENTILATION SHAFTS OF ROAD TUNNELS. EXHAUST EMISSION INFORMATION IS TO BE COLLECTED ALONG THE GROSSGLOCKNER HIGH ALPINE ROAD FOR VEHICLES WITH PETROL AND DIESEL ENGINES.
