- Description
- Microplastics are an emerging contaminant in aquatic environments. Information on the occurrence and characteristics of microplastics in Australia is limited and their interactions with chemical contaminants have not been addressed. Therefore, the aim of this study was to generate baseline information on the physical and chemical characteristics of microplastics on Australian shorelines to facilitate further detailed risk assessment. Field collected microplastics were categorised by colour, shape and polymer type. Plastic particles were primarily clear, blue, white and green and consisted mainly of fragments (57.80%) and pellets (30.68%). Polymer characterisation revealed that shoreline microplastics were polyethylene (53.17%), polypropylene (35.17%), polystyrene (6.61%) and polyethylene terephthalate (1.85%). Analysis of metal(loid)s found that concentrations of Mn, Cr, Cu, As, Zn and Pb were significantly higher on microplastics associated with industrial locations compared with other land uses, indicating that aged microplastics have the potential to adsorb toxic metals and that metals levels may be location-dependent.
