According to the London Air Quality Network the maximum of 36 days per year happened on Tuesday

Campaigners in Neasden have called for Brent council to intervene after a street blighted by dirty air has clocked up more polluted days more than anywhere else in the capital this year.

According to the London Air Quality Network (LAQN), Neasden Lane reached the maximum of 36 Bad Air Days per year on Tuesday (11).

This means any further days could be breaking legal requirements on pollution levels.

Jugal Mehda, chairman of Neasden Neighbourhood Watch and a long standing campaigner against the pollution told the Times that ‘enough was enough’.

He said: “This has been a problem for too many years now. The council has the power to do something about so they must take action now.

“It has been going on far too long and people are suffering.”

It is claimed that the poor quality of air is due to waste transfer activities at Neasden Goods Yard and the proximity of the North Circular Road.

Last year the maximum amount of pollution allowed was exceeded 77 times, more than double the acceptable level.

Mr Mehda, 78, added: “My main concern is for the people who live there and cannot get any fresh air because are forced to keep their windows and doors closed.

“You only have to spend just a few minutes there to realise the extent of the problem there are dust and particles everywhere.”

Simon Birkett, founder and director of campaigning group Clean Air in London, who work closely with LAQN in their attempts to combat pollution said levels were ‘dangerously high’.

He said: “This is not dust these are invisible and dangerous airborne particles including some which are toxic or carcinogenic.

“The Neasden Lane breach is the latest evidence that there has been a failure to address the biggest public health crisis for decades.”

Brent council confirmed that a monitoring station which had been set up on site showed that standards for air quality were ‘repeatedly breached’.

A spokesman said they have had concerns with the poor air quality for some time.

He added: “We want to protect the health of local people, so we are now taking a number of steps to address the issue including working closely with the Environment Agency to develop enforcement action and trying to identify exactly what the sources of the dust are and cleaning it up.”
