Abstract
Continuous hourly measurements of volatile organic compounds (VOC) from C2
to C10 were performed in Dunkerque, northern France from August 2002 to
September 2003. The receptor site was chosen to be influenced by both urban
and industrial VOC emissions. First the analysis of concentrations according to
the wind direction has allowed us to prove this double influence for benzene and
octane whereas seasonal and daily time series have only permitted us to
formulate hypotheses. Secondly the scatter plots of compounds versus acetylene,
a traffic exhaust tracer, have confirmed this double origin for the two
compounds. Then a simple regression analysis has allowed us to reach the
hydrocarbon/acetylene ratio characterizing the traffic exhaust source. Finally this
traffic
