PAHs in SDB marina sediments appear to be derived largely from pyrogenic sources Parent PAHs accounted for over 96% of the total 36 PAHs targeted in this study High molecular weight PAHs (4–6 rings) were dominant (> 86%) in marina sediments ‘Hotspots’ of PAH concentrations suggest an association with stormwater outfalls Percentage of potentially carcinogenic PAHs was high in all sites (61–70%)
