Oceanographer and lead researcher Julia Reisser a PhD candidate at UWA’s Oceans Institute and School of Environmental Systems Engineering, says this information is an important step in quantifying the plastic hazards that threaten Australian species and marine regions. “The high number of small plastics present in our oceans is a toxic threat to marine organisms and environments,” she says. “They contain hazardous ingredients from manufacturing, like Bisphenol A, as well as pollutants adsorbed from the seawater, which are bioaccumulated up the marine food chain. “Until now, we had little idea how much these tiny plastics were present in Australian waters.” Ms Reisser conducted sea surface net tows at 57 locations around Australia, enabling her to collect the characteristics and concentration of marine plastics in Australian waters.
