EMISSIONS FROM TIRES IN DEDICATED USE

In view of publications from Sweden (KEMI, 1994) focus was given to th e polyaromatic hydrocarbon (PAH) emissions from tires in dedicated use . With respect to chemical analyses of new and used tires, of abrasion -material, soil-and street-drainage-samples we found low PAM-pollution and much lower than those reported from Sweden. On busy highways the pollution with tire-specific substances at the roadside is obvious, bu t some meters away from the roadside no suspicious PAM-pollution was o bserved. It is supposed that the photolytic degradation effect to smal l abrasion particles is high enough, that no enrichment of organic add itives from fires is observed.
