Following the disappointing results of your dust suppressant trials of applying 'glue' to stick particulate matter to polluted main roads, do you still intend to continue with this programme on road corridors?

The full results from the trial of dust suppressants are included in the Clean Air Fund End of Programme Report (

The trial provided evidence of a beneficial effect of the application of dust suppressants at some road locations and at industrial waste sites, however, the variable findings from the road corridor study sites do not support significant future application along road corridors in London as a measure to reduce PM10.

For this reason, the future roll out of dust suppressants will focus on industrial sites and roads near construction sites and road works, where the greatest benefits can be achieved.
