Issued: 23/02/2018 11:57:58

Pollution Band: Low


Details

Saturday and Sunday forecast to be sunny and mainly dry, feeling very cold.
Air arriving over the weekend is expected to have have spent some time over the Baltic before sweeping down at high altitude across central Europe and the near continent. High wind speeds should ensure the arriving air flow will bring little in terms of additional industrial and urban pollutants en route.
Monday will start with low temperatures and possible snow arriving from the continent.
Lower emissions over the weekend and strong wind speeds should ensure good dispersion of local emissions.

Pollution is expected to remain low for the following pollutants:

Nitrogen dioxide
Ozone
PM10 Particulate
PM2.5 Particulate
Sulphur dioxide







This forecast is intended to provide information on expected pollution levels in areas of significant public exposure. It may not apply in very specific locations close to unusually strong or short-lived local sources of pollution.

The Ealing 8 monitoring site on Horn Lane, Acton forms part of an investigation of the local PM10 sources at this location. The site is affected by specific local sources of PM10 particulate and it is not representative of other areas within the Borough.


How to use the Daily Air Quality Index *

  • Step 1: Determine whether you (or your children) are likely to be at-risk from air pollution. Your doctor may also be able to give you advice.
  • Step 2: If you may be at-risk, and are planning strenuous activity outdoors, check the air pollution forecast.
  • Step 3: Use the health messages corresponding to the highest forecast level of pollution as a guide.
Air Pollution Banding Value Accompanying health messages for at-risk groups and
the general population
At-risk individuals ** General population
Low 1-3 Enjoy your usual outdoor activities.

Enjoy your usual outdoor activities.

Moderate 4-6 Adults and children with lung problems, and adults with heart problems, who experience symptoms, should consider reducing strenuous physical activity, particularly outdoors. Enjoy your usual outdoor activities.
High 7-9 Adults and children with lung problems, and adults with heart problems, should reduce strenuous physical exertion, 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. Anyone experiencing discomfort such as sore eyes, cough or sore throat should consider reducing activity, particularly outdoors.
Very High 10 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. Reduce physical exertion, particularly outdoors, especially if you experience symptoms such as cough or sore throat.

* Adults and children with heart or lung problems are at greater risk of symptoms. Follow your doctor's usual advice about exercising and managing your condition. It is possible that very sensitive individuals may experience health effects even on Low air pollution days.
