Abstract

Street dust samples collected from a network of urban, suburban and industrial locations within Derby were analysed for PAH concentrations by reverse phase HPLC and fluorescence detection. Profiles of 12 PAH were determined for each sample and standardised profiles generated for source categories including : engine oil, petrol vehicle exhaust and diesel vehicle exhaust. The vehicle exhaust profiles were derived from weathered dust samples collected from an enclosed multi-storey car park and a bus depot for petrol and diesel respectively. Engine oil profiles were established, by analysing crankcase oils from a range of vehicle types. Other source profiles were obtained from the literature. Source apportionment was conducted on
