<p>New research by scientists from the University of Plymouth and Newcastle University has shown that the presence of wetlands and retention ponds alongside major highways led to an average reduction of almost 75% in the mass of tyre wear particles being discharged to aquatic waters. The researchers say that while the number of retention ponds and wetlands in the UK is quite small, the study has international significance as to the most effective ways to mitigate against the potential impacts of tire pollution on a global scale.</p>
