Massive amounts of toxic trash are pouring into the North Sea every year through the Rhine, poisoning its waters with heavy metals, microplastics, and other chemicals. The research has found that this litter is having a devastating impact on both the environment and human health.
Tyres, for example, contain high levels of zinc and other toxic substances that can be deadly to ecosystems in large quantities. Even natural materials like worked wood, paper, cardboard, and food waste can have toxic or hazardous additives.
Rivers play a significant role in transporting litter into other aquatic environments, including the North Sea. The study found that the composition of litter in the Rhine is similar to that found in other European rivers, such as the Thames. This large quantity of trash also poses a significant risk to infrastructure like drainage systems, which can lead to increased flooding.
Citizen scientists and researchers from the University of Bonn collected litter from the Rhine between 2022 and 2023 and found that up to 4,700 tonnes of "macrolitter" โ pieces larger than 25mm in size โ are carried by the river annually. While more research is needed to understand the full extent of the problem, the study highlights the need for urgent action.
Dr Leandra Hamann, lead author of the study, praised the work of citizen scientists who collected litter and transported it to the monitoring site using a custom-made app. The study was published in the journal Communications Sustainability and underscores the pressing issue of plastic pollution in our rivers and oceans.
