Pollution from roads affects virtually every part of Britain, with 94% of land having some pollution above background levels, according to research.
Roads, which occupy less than 1% of the country, “form vast, pervasive and growing networks, causing negative environmental impacts”, the scientists said.
The most widespread pollutants are tiny particles, mostly from fossil fuel burning, nitrogen dioxide from diesel vehicles, and noise and light. More than 70% of the country is affected by all of these, with the only land to escape road pollution being almost entirely at high altitudes.
