The Bradford district has four areas which officially exceed national pollution limits however a recent review indicates three more could soon be added to the list.
Diesel lorries and busses cause much of the pollution, despite only accounting for six per cent of traffic, according to experts.
Air pollution can cause childhood asthma, cancer, strokes and heart attacks and accounts for an estimated 222 deaths in the district each year, but the leader of Bradford’s Green group fears the victim toll could be much higher.
Councillor Martin Love, said “Bradford Council has arguably been at the forefront of efforts to clean up air pollution. Bradford has a number of new cycle paths and the ‘greening’ of older and more polluting busses are some of the projects already complete.”
Bradford Council is currently drafting its annual air quality report to the Government, which will identify whether pollution in the areas of concern remain high.
