Defra warns of 'summer smog'
Sunny, warm weather over Southern and Eastern England over the next few days is likely to lead to the first summer smogs of 2006, Defra has warned.
High ozone levels are forecast from Saturday for Eastern and Southeast England and East and West Midlands and are likely to persist at least until Monday.
Ground level ozone is formed when sunlight acts on nitrogen dioxide and other atmospheric substances close to the ground. The pollutants that cause ground level ozone come from a range of sources, including petrol and other fuels.
Air pollution is described as 'low' (1-3), 'moderate' (4-6), 'high' (7-9) or 'very high' (10).
Some people are more sensitive to ozone than others and may begin to notice an effect on their breathing. Those suffering from lung diseases, including asthma, and heart conditions should be especially aware of ozone levels.
People with asthma are not necessarily more sensitive but can use their 'reliever' inhaler if they are affected.
The public are being advised to take sensible precautions, including avoiding exercising outdoors in the afternoon in order to reduce exposure to ozone and avoiding making unnecessary short car journeys wherever possible, by walking, cycling or making use of public transport instead.
The Met Office has also issued the first health warning of the summer, as the UK looks set to have its hottest spell of weather so far this year.
Some areas are facing heatwave conditions, with day-time highs of between 28 - 30C over the coming days, coupled with warm nights, meaning that health concerns are heightened.
The Met Office said that with many sporting and charity events taking place around the country, the strength of the sun and the combination of heat and humidity will also be important factors to consider.
Regular updates on ozone levels are available on Teletext page 156, on the website: www.airquality.co.uk or from Defra's freephone helpline on: 0800 556677, which also offers health advice to those who may be particularly sensitive to air pollution.
