Abstract
Measurements made in the period 1992-94 (Miljøprojekt 285, 1995) indicated, that the
levels of PAH and mutagens was reduced during period. It was estimated that explanations
could be the increased use of catalytic converters and the introduction of an improved
diesel fuel. The measurements in this project confirm, that a significant reduction of PAH
and mutagens took place during the period 1992-1996. The reduction of the
PAH-concentration has been estimated to about 35%. It is concluded that 2/3 of the
reduction is due to the use of the improved diesel quality and 1/3 to the increased use of
catalytic converters.
Resumé
Målinger foretaget i 1992-94 af PAH-niveauet i København
(Miljøprojekt, 285) indikerede, at der fra 1992 til 1993 skete et
fald af PAH og mutagener i byluften. Mulige årsager blev skønnet at
være øget andel af katalysatorbiler og introduktion af nyt
dieselbrændstof til busser. Dette projekt har haft til formål at
be- eller afkræfte disse antagelser. Undersøgelsen viser, at der i
perioden 1992-1996 er sket et kraftigt fald i luftens indhold af PAH
og mutagener. PAH-indholdet er reduceret med omkring 35%. Det
konkluderes, at 2/3 af de målte reduktioner kan henføres til
anvendelsen af ultralet diesel og 1/3 til det øgede antal
katalysatorbiler.
