Recently Londoners we’re given health warnings about air pollution: the elderly and those with breathing difficulties were advised to listen strenuous exercise and to stay inside. A spell of high pressure weather mean that the air over London had remained static for several days: no winds had been moving the air on and bringing in fresh. As the air wasn’t moving nor were the noxious chemicals and small particulates moving. Instead concentration levels of these pollutants were rising.
Where do these pollutants come from in the first place? Exhausts from vehicles, dust from brake blocks and tyres, smoke from wood burning fires, exhausts from gas and oil boilers, dust from construction sites, exhausts from waste incinerators and from industrial plants. Of all the sources of pollution generated in London, over 50% comes from vehicles! It would seem that we Londoners are the cause of much of the problem. Can we drive less? Can we become less reliant on polluting vehicles to deliver goods and services? Can we encourage active travel – walking and cycling?
