Marine debris and chemical contaminants are both globally recognised risks to the health of the environment, economy, and human health (UNEP 2021 and 2022). However, the interaction and synergistic effects of marine debris particles and chemical contaminants is currently poorly understood. Plastic debris contains toxic plasticisers but can also act as vectors for other contaminants, such as heavy metals and persistent organic pollutants, increasing its toxicity potential if ingested. This is a major concern for the health of coastal organisms that may be exposed to debris particles, such as endangered sea turtles and sea birds, putting them at increased risk of accumulating contaminants. Despite the priority for researchers, government agencies and policy makers, there is currently a paucity of information identifying the areas of high risk of both pollution and marine debris around Australia’s coastline. Through spatial analysis using data from a wide range of sources, including AMDI, this study highlights hotspots of coastal debris pollution that may be further contaminated by chemical pollution. This information is integral for researchers to determine where on-ground sample collection and field work should occur, as well as policy makers to reduce the impacts of debris pollution and land-based contaminants on the coastal environment.
