The pollution associated with roads includes nanoparticles (from engines, tyres and brake linings); nitrogen dioxide (mainly from diesel engines), as well as noise and light. The detrimental effects of these pollutants on human health and wildlife are very well-documented. Their dangers have been known for decades and upper, legal limits specified. A recent study has found, however, that 94% of land in the UK, is affected by road pollution. In deed, 70% of our 'green and pleasant land' is affected by
all four components (

This, obviously, is not really possible for more than a handful of folk. It is remarkable so little has been done about reducing road pollutants in the UK. I suspect it reflects the power of the motoring lobby. One must stress, that even a transition to all electric vehicles, will
not remove all sources of pollution from around our roads.
It's necessary, where possible, to replace diesel and petrol-fueled vehicles by electrical equivalents. Electric vehicles (EVs) don...
