Apparently I live in the worst 10 percent air quality area in Britain, due to the huge arterial road nearby. A new scheme is piloting a ‘dust supressant’ trial to do something about the fine black dust that sifts down around us.
The dust is in all cities – it’s caused by tyre and brake abrasion, and associated with a range of health problems. A report for the Mayor said that over 4,000 early deaths were caused by long term exposure to air pollution.
The suppressant is a a biodegradable saline solution made up of Calcium Magnesium Acetate that sticks the particulate matter to the carriageway and prevents it re-circulating in the air. If it works, it will be used on all major roads in the capital.
London is a very green city in summer, but it would be nice if this initiative could be coupled with the planting of a lot more trees.
