PM2.5 (particulate matter not exceeding 2.5 micrometres) is monitored on the London Road in Bath and most recent annual levels are equal to the World Health Organization’s guideline levels.
PM10 (larger particulate matter not exceeding 10 micrometres) is also monitored on London Road and Lower Bristol Road and are close to the World Health Organization’s guideline levels but below the UK National Objective.
There is no proven safe level of PM2.5 and it is not visible. So the more we can do to reduce emissions the better.

The Burn Right campaign also provides valuable information about wood burning and air pollution.
