IMPACT OF URBAN TRAFFIC ON MAN AND ENVIRONMENT. CARCINOGENIC SUBSTANCES IN VEHICLE EXHAUST

STADSTRAFIKENS INVERKAN PAA MAENNISKA OCH MILJOE. CANCERFRAMKALLANDE AEMNENIAVGASER

This work is a summary of documented knowledge in the area of carcinogens, considering the chemical and physical properties as well as the ambient concentrations and effects of these substances. This documentation is meant as a basis for a scientific technical discussion of possible measures in order to reduce the exposure to carcinogenic substances, primarily carcinogenic polynuclear aromatic hydrocarbons, in the urban environment. Among the primary conclusions reached, the following may be mentioned: (1) the difficulties in measuring cpah components must be considered when evaluating single measurements, (2) a series of parallel influences must also be considered, e.g. Exposure to asbestos, nitrogen dioxide, aldehydes, or sulphur oxides, (3) exposure to cpah in the urban environment may be considerable and even at the same level as from smoking, (4) the exposure to carcinogenic substances may result in cancer disease also in other areas besides the lung, (5) auto exhaust and asphalt wear are the dominant sources of cpah levels in urban areas and (6) diesel powered vehicles, e.g. Trucks and buses, may in certain areas contribute to the majority of cpah emissions. /TRRL/
