Permeable pavement roads may save salmon from tire particle toxins
While stormwater runoff pollutants in general aren't great for aquatic animals, chemicals from tire particles are particularly harmful to salmon. A recent study now shows that permeable pavements could keep most of those toxins from ever reaching the fish.Ordinarily, when rainwater runs along city streets, it carries pollutants from those streets down the storm drains and out into the local waterways. One proposed method of addressing that problem involves replacing existing road surfaces – or building new ones – with…
