An international research project has revealed the highest levels of microplastic ever recorded on the seafloor.
According to a research paper published in Journal science, over 10 million tons of plastic waste enters the oceans each year.
Microplastics on the seafloor are mainly comprised of fibres from textiles and clothing. These are not effectively filtered out in domestic waste water treatment plants, and easily enter rivers and oceans.
This study provides the first direct link between the behaviour of sea currents and the concentrations of seafloor micro plastics and the findings will help to predict the locations of other deep-sea microplastic hotspots and direct research into the impact of micro plastics on marine life.
