Retention ponds and wetlands constructed as part of major road schemes can reduce the quantities of tyre particles entering the aquatic environment by an average of 75%, new research has shown.
Retention ponds and wetlands constructed as part of major road schemes can reduce the quantities of tyre particles entering the aquatic environment by an average of 75%, new research has shown.
The study analysed samples collected alongside some of the busiest routes in South West England and the Midlands, many used by more than 100,000 vehicles each day.
Tyre particles were discovered in each of the 70 samples taken, confirming the findings of previous research which has shown them to pose a considerable environmental threat.
However, the presence of wetlands and retention ponds led to an average reduction of almost 75% in the mass of tyre wear particles being discharged to aquatic waters, thus providing protection for rivers and the ocean beyond.
