Polluted cities and towns like Portsmouth and Dartford raise early death risk

Living in the UK's most polluted cities and towns increases the risk of an early death by the equivalent of smoking 150 cigarettes a year, a charity has warned.

The British Heart Foundation's analysis shows that people living in areas such as Portsmouth, Dartford, Medway, Gravesham and Thurrock are badly affected.

The BHF wants the next government to urgently introduce tougher World Health Organisation (WHO) air pollution limits. It said current EU limits - which the UK comfortably meets - for fine particulate matter (PM2.5) are 25 micrograms per metre cubed as an annual average. The WHO limits are tougher - at 10 micrograms per metre cubed as an annual average.

The BHF said PM2.5 can have a "seriously detrimental effect to heart health", increasing the risk of heart attack and stroke and making existing health problems worse. It says that around 11,000 coronary heart disease and stroke deaths each year in the UK are caused by particulate matter air pollution.

"Air pollution is a major public health emergency and over many years it has not been treated with the seriousness it deserves. Unless we take radical measures now to curb air pollution, in the future we will look back on this period of inaction with shame.

"As these figures show, the effect of air pollution on our heart and circulatory system is profound, and we have no choice over the air we breathe in the places we live. Legislation was passed over a decade ago to protect people from passive smoke, and similarly decisive must be taken to protect people from air pollution.

"The last government accepted that it is possible to implement tougher WHO air pollution limits, and the next government must now do so protect the health of the nation."
