Public Health England scientists are urging members of the public to consult detailed air quality maps on Defra’s website before planning strenuous outdoor activity.
In the last few days a combination of local emissions, light winds, pollution from the continent and dust blown over from the Sahara caused a spike in the UK Air Quality Index compiled by the Department for Environment, Food and Rural Affairs (Defra).
And those higher than usual levels of pollution may bring on health effects in some.
Dr Sotiris Vardoulakis, head of the air pollution and climate change group at PHE’s Centre for Radiation, Chemical and Environmental Hazards said:
PHE provides advice to Defra on the health effects of air pollution.
While most people will not be affected by short term peaks in air pollution, some individuals, particularly vulnerable groups such as those with existing heart or lung conditions, may experience increased symptoms.
On occasions where levels are high, 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.
Although forecasts are for pollution levels fall over the next 24 hours or so it’s important that people consider their personal circumstances and the maps before planning any particularly strenuous outdoor activity. It’s important people are well informed so they can make their own judgements about their levels of activity
