Heathrow third runway may mean more pollution deaths, study says
The research,
funded by US university MIT, suggests Heathrow aviation pollution causes about 50 early deaths a year and this number is rising.
That figure may climb to 150 if a third runway is built, the study claims.
If Heathrow closed and an airport was built in the Thames Estuary, there would be 50 deaths annually, it said.
He told the BBC: "Because of the location of the [Thames estuary] airport, such an airport would be further away from major population centres so fewer people would be exposed to pollution from that airport.
"Another important factor is the winds in London are south-westerly, so towards the north-east, so pollution from Heathrow gets blown over London.
"If you instead had an airport in the Thames Estuary, that pollution would get blown over the English Channel and North Sea," he added.
