Recent studies have revealed alarming levels of microplastics in all major European rivers, with an average of three particles per cubic metre of water. During the extensive research coordinated by Jean-Francois Ghiglione, significant findings included that the invisible microplastics present in the water column far exceed visible ones in mass. Fast-flowing rivers like the Rhone and the Seine are particularly problematic, with thousands of particles flowing through each second. This study highlights the urgent need for addressing the microplastic pollution crisis as it poses a real threat to aquatic ecosystems across Europe.
"Alarming" pollution of on average "three microplastics per cubic metre of water" was observed in all European rivers studied, indicating widespread microplastic contamination.
"The mass of microplastics invisible to the naked eye is more significant than that of the visible ones," said Ghiglione – researchers were surprised by the findings.
On the Rhone in Valence, the fast flow of water means there are "3,000 plastic particles every second" being recorded, raising concerns about river pollution.
Samples were collected from the mouths of major rivers by some 40 chemists, biologists, and physicists from 19 research laboratories, showcasing a collaborative effort.
