Abstract
Resultaten van metingen van PAK concentraties op negen
dagen op drie typen lokaties (landelijke achtergrond, stadsachtergrond,
drukke verkeersstraat) zijn statistisch geanalyseerd. Onderzocht is de
bruikbaarheid van individuele PAK (22 componenten) als indicator voor de
carcinogene potentie van het PAK-mengsel. Het best voldoen benzo[e]pyreen,
chryseen en benzo[a]antraceen. Benzo[a]pyreen, de huidige PAK-gidsstof,
voldoet eveneens. Voorts zijn de mogelijkheden onderzocht voor bewaking van
de PAK-norm met behulp van andere luchtverontreinigende stoffen (zwarte
rook, PM-10, CO, NOx, SO2). Zwarte rook en NOx toonden de beste
resultaten.
PAH concentrations were measured in city areas on nine days with calm weather at three types of sites (rural backgound, city background, road with heavy traffic) were statistically analyzed. Twenty-two PAHs were examined individually to determine the utility of each as an indicator of the carcinogenic potency of a PAH mixture. Benzo[e]pyrene, chrysene and benzo[a]anthracene scored the highest, along with the current PAH indicator, benzo[a]pyrene. Furthermore, a survey on possibilities for maintaining the PAH standard with the aid of other compounds (black smoke, PM-10, CO, NOx, SO2) showed the best results with black smoke and NOx.
