Some people are more sensitive to ozone than others and may begin to notice an effect on their breathing. People with asthma are not necessarily more sensitive but, if affected, can use their ‘reliever’ inhaler. The public are urged to take sensible precautions such as:
avoiding exercise outdoors in the afternoon can reduce exposure to ozone; and
avoiding making unnecessary short car journeys wherever possible can reduce the formation of ozone.
Regular updates on levels of particulate matter (PM10), sulphur dioxide, nitrogen dioxide, ozone and carbon monoxide are available at: uk-air.defra.gov.uk (UK Air Information Resource) and from Defra’s freephone helpline (0800 556677), which also offers health advice to those who may be particularly sensitive to air pollution.
