Classification | Index | pm10 | pm2.5 | Our measurement values above are real-time values The health effects should be based on 24 hours average values only. |
---|---|---|---|---|
Good | 1 | < 16 μg/m3 | < 11 μg/m3 | Enjoy your usual outdoor activities |
2 | < 33 μg/m3 | < 23 μg/m3 | ||
3 | < 50 μg/m3 | < 35 μg/m3 | ||
Fair | 4 | < 58 μg/m3 | < 41 μg/m3 | Enjoy your usual outdoor activities Adults and children with lung or heart problems, who experience symptoms, should consider reducing strenuous physical activity, particularly outdoors |
5 | < 66 μg/m3 | < 47 μg/m3 | ||
6 | < 75 μg/m3 | < 53 μg/m3 | ||
Poor | 7 | < 83 μg/m3 | < 58 μg/m3 | Anyone experiencing discomfort such as sore eyes, cough or sore throat should consider reducing physical activity, particularly outdoors. Adults and children with lung problems, and adults with heart problems, should reduce strenuous physical activity, particularly outdoors, and particularly if they experience symptoms. People with asthma may find they need to use their reliever inhaler more often. Older people should also reduce physical exertion. |
8 | < 91 μg/m3 | < 64 μg/m3 | ||
9 | < 100 μg/m3 | < 70 μg/m3 | ||
Very poor | 10 | > 100 μg/m3 | > 70 μg/m3 | Reduce physical exertion, particularly outdoors, especially if you experience symptoms such as cough or sore throat. Adults and children with lung problems, adults with heart problems, and older people should avoid strenuous physical activity. People with asthma may find they need to use their reliever inhaler more often. |

Update your browser to see a graph of PM10 and PM2.5 pollution levels over the last week.Click to enlarge the above graph of the air pollution at Chambers Grove, Thorncliffe.
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.
The St. Marys Lane sensor was obtained from Clean Air Sheffield with the assistance of Frack Free Ecclesfield and Chapeltown, and the support of the Ecclesfield Conservation and Local History Group.
