Plastics pollution has quickly become recognised as one of the biggest environmental issues of the current era with urban centres a major contributing source. However, there is still very little understanding on the impact of urban centres on sensitive aquatic systems in Australia including catchments of the Great Barrier Reef. As such a scoping study of 5 key urban centres in Queensland was conducted, with a total of 21 surface water sites sampled and analysed for concentrations of 6 common microplastics, tyre wear particles and a suite of 15 tyre additives including the transformation product 6PPD-quinone which is highly toxic to certain aquatic species. Polyethylene and polypropylene were the dominant plastics detected (16 – 1750 and <0.7 – 37 µg/L respectively) with polystyrene, poly (methyl)methacrylate and polycarbonate detected less frequently. Styrene butadiene rubber was detected in the majority of samples equating to between 8 – 22 and 6390 – 18,470 µg/L of tyre road wear particles (TRWPs) in samples. Tyre additives were detected in all samples with concentrations Σ15additives ranging 2.9 – 2540 ng/L and concentrations of 6PPD-quinone lower than previous studies at <0.05 to 24 ng/L. There was no correlation between concentrations of polymer, TRWPs or additives demonstrating the varied anthropogenic sources at each site. A traffic related profile of tyre additives was determined at sites with highest concentrations and known local traffic related inputs that can assist future monitoring studies with determining sites of high impact. Finally, all samples were collected during the dry season and this study provides information on sites that should be further monitored during the wet season when concentrations of these pollutants are expected to be elevated.
