Horn Lane is one of the most polluted roads in London. In June it was the first area in the capital to breach clean air targets according to King's College London.

But after eight years of monitoring by the council and the Environment Agency little action has been taken to control the dust which residents say cause chronic health problems.

On July 12 the Environment Agency organised a visit by them, the council, MP Angie Bray and Nikki Howard, a member of residents group Stop Horn Lane Pollution. It was prompted by Ms Bray raising the issue in parliament the month before.

All firms on the site agreed to regular meetings with the Environment Agency and residents.

Waste management plant Gowing and Pursey see whether they can fully enclose their yard.

A rail terminal for building materials called Aggregate said they would look at installing a large rubberised curtain around their work area to cut down dust.

While Hanson is submitting a retrospective planning application after redeveloping its concrete plant in 2011.

Although residents say they are not hopeful that even these measures will be implemented, especially as Hanson has already missed Friday's deadline to submit the application. A spokesman for the company could not explain the missed deadline but said the new plant was not much bigger and was less polluting, although residents say this is not the case.

Stop Horn Lane Pollution member Nikki Howard, said: “The measures should have an effect but will it be implemented? We’re dealing with the council and the environment agency and we know what track record they’ve got. Monitoring has been going on for eight years and pollution is just as high.”

Ms Bray said the area should be used for something else which could benefit residents and take advantage of Crossrail coming to Acton mainline next door.

She said: "These interim measures will help but they’re not the solution. I think the whole area needs to be re-zoned."
