) contained on average 1.59 ± 2.62 items per individuals and 0.39 ± 0.95 items per individual, respectively. The greatest proportion of contaminated individuals was in December 2018 (winter; 75%) followed by March and June 2019 (spring; 42% and summer; 43%, respectively). Seasonal factors, such as rainfall, can affect plastic accumulation in an estuarine system, but these microplastics are not always bioavailable. Understanding the drivers of this variability is key in designing mitigation strategies and managing risk.This article is part of the Theo Murphy meeting issue 'Sedimentology of plastics: state of the art and future directions'.
