The monitoring station is within the grounds of the Council offices. The site is next to the B1052, near to a mini roundabout as you drive in to Saffron Walden.
The Daily Air Quality Index (DAQI) has been developed to provide advice on expected levels of air pollution. In addition, information on the short-term effects on health that might be expected to occur at the different bands of the index (Low, Moderate, High, Very High) is provided. Our aim is to educate and inform, however if you are concerned DEFRA provide a free automated telephone service on 0800 556677.
It is possible that very sensitive individuals may experience health effects even on low air pollution days. However, air pollution in the UK does not rise to levels at which most people need to make major changes to their habits to avoid exposure; you needn’t fear going outdoors, especially when armed with information about cause and affect.
It is known that, when levels of air pollutants rise, adults suffering from heart conditions, and adults and children with lung conditions, are at increased risk of becoming ill and needing treatment. Only a minority of those who suffer from these conditions are likely to be affected and it is not possible to predict in advance who will be.
Some people are aware that air pollution affects their health: adults and children with asthma may notice that they need to increase their use of inhaled reliever medication on days when levels of air pollution are higher than average. Older people are more likely to suffer from heart and lung conditions than young people and so it makes good sense for them to be aware of current air pollution conditions.
At very high levels of air pollution, some people may experience a sore or dry throat, sore eyes or, in some cases, a tickly cough even in healthy individuals. Children need not be kept from school or prevented from taking part in games.
When levels of air pollution increase it would be sensible for those who have noticed that they are affected to limit their exposure to air pollutants. This does not mean staying indoors, but reducing levels of exercise outdoors would be reasonable.
Pollution is caused from natural or man-made actions. There are many types of pollutants produced from a variety of sources. Pollutants are classified as primary or secondary:
Primary Pollutants These are gases or particles that are blown into the air. Historically, the main air pollution problem has typically been high levels of smoke and sulphur dioxide emitted following the combustion of sulphur-containing fossil fuels such as coal, used for domestic and industrial purposes. These days, the pollutant of most particular concern is is carbon monoxide that comes from motor vehicle traffic.
Secondary Pollutants These are just as harmful as primary pollutions and are not emitted directly; they form in the atmosphere when primary pollutants join together in a chemical reaction:
