Ecclesfield Air Quality is normally extremely good. We may be able to further reduce our exposure however, by checking that both the current Indexes at the top of this page are "1" before going outdoors or exerting ourselves. The readings may also guide the use of an air filter.
We have read that any problems from air pollution are typically triggered by exposure to PM10 accumulated over 24 hours, in which case the average of the Last 24 hours PM10 graph would be the most relevant. However these acute effects of air pollution can last two days, so it might be useful to also switch to Last week's PM10 graph and look back at the day before.
The best estimate of the significance of these readings for the general population that we have found is that our annual risk of death, and the death rate of the people around us, would decrease by 0.6% for each 1μg/m3 reduction in average PM2.5 achieved. Reductions are likely to be even more vital for people suffering from respiratory or cardiovascular conditions, and are also likely to be of greater concern to expectant mothers and parents of growing children. However, in the absence of such specific information, we take the figure above as a measure of the general risk of developing serious medical and psychological problems, making reduction in exposure to particulates a vital concern to everybody.
