Smog-levels are 'very high'

VERY high levels of air pollution were last week being monitored in Londonderry.

The localised air pollution was likely to be associated with the build up of emissions from vehicles and home heating systems during the calm, cold weather conditions experienced across Northern Ireland.

The DoE said wind increases on Boxing Day were likely to have improved the situation.

During periods of high pollution the symptoms of people with lung or heart disease may worsen. Healthy people are unlikely to experience any ill effects.

Hourly updates on levels of particulate matter (PM10), sulphur dioxide, nitrogen dioxide, ozone and carbon monoxide are available on the DOE website at http://www.doeni.gov.uk and the freephone helpline 0800 556 677, which also offers health advice to those who may be particularly sensitive to air pollution.

In the past smog-levels at the densely populated Dale's Corner junction in the Waterside resulted in it being recommended as a special Air Quality Management Area (AQMA).

Increased levels of Nitrogen Dioxide (NO2) have been found at the busy junction over recent years.

Research suggests long-term exposure to NO2 may decrease lung function and increase the risk of respiratory symptoms such as acute bronchitis and cough and phlegm, particularly in children

The DoE advise that air pollution is described as "low (1-3)", "moderate (4-6)", "high (7-9)" or "Very High (10)" in relation to the presence of particulate matter, sulphur dioxide, nitrogen dioxide, carbon monoxide and ozone. Classifications are based upon the pollutant in the highest band based upon the advice of the independent Committee on the Medical Effects of Air Pollution.

When pollution is high, sensitive people may notice their symptoms worsen and may need to act to reduce the symptoms or their exposure to the pollution.

Asthmatics will find that their symptoms will ease through use of their relief inhaler in the usual way advised by their doctor.

Others affected by the pollution may wish to reduce the time they spend outdoors or avoid busy, congested streets. If symptoms persist, affected people should consult with their doctor.

Road vehicles are considered a major source of many pollutants in urban areas. If you must drive, switch off the engine if you expect to be stationary for more than a couple of minutes, and drive smoothly - it will save you fuel and money and you will emit less pollution.
