Defra today (January 24) confirmed â€œvery high pollutionâ€ in London in terms of air pollution as well as in some specific points in eastern England.
In a statement the Department for Environment, Food and Rural Affairs said that â€œWidespread moderate air pollution currently being measured across many parts of the UK today (24 January) due to still and foggy weather conditions, with some areas of high pollution across southeast England, very high pollution in London and isolated pockets of very high across eastern England.â€
The Department said that high levels are expected across southeast England and some very high levels in London and the east of England. â€œModerate levels are being measured in south Wales, South West England, the East and West Midlands, Yorkshire and Humberside and Northwest England. Air pollution is expected to remain low across Scotland and Northern Ireland.â€
The reason for the air pollution, according to Defra is continuing high pressure and associated light winds.
Health advice was also given alongside the air pollution report.
Defra stated: â€œFor those parts of the country forecast to have very high levels of ambient air pollution, Public Health England is advising people to reduce physical exertion, particularly when outdoors and especially if they experience symptoms such as a cough or sore throat. Adults and children with lung problems, adults with heart problems, and older people, in areas where very high levels are recorded should avoid strenuous physical activity. People with asthma may find they need to use their reliever inhaler more often.â€
Looking ahead, it is expected that light winds and foggy conditions are expected to continue through Tuesday (24 January), especially across southern and eastern parts. â€œThis will lead to the ongoing risk of areas of moderate air pollution levels, along with isolated pockets of high levels. Meanwhile across the north and west increasing winds should lead to air pollution returning to low levels from Wednesday (25 January).
â€œThese low levels are expected to spread to all parts during Thursday (26 January) and Friday (27 January) as stronger winds extend east across the UK.â€
Defra also pointed out that the 5-day forecast of predicted air pollution levels is â€œcontinually updated on the UK Air website, with advice from Public Health England to allow members of the public, particularly those who are most likely to be affected by air pollution, to take action.â€
And, the statement also noted that Defra works â€œwith health charities to make sure vulnerable people are aware of any periods of low air qualityâ€.
