The number of heart attacks and stroke deaths connected to toxic air could reach 15,000 across the East of England in the next decade, a charity is warning.
The British Heart Foundation is calling for stricter air pollution limits as it launches a new awareness campaign.
The county with the highest number of estimated deaths is Essex at 4,900.
The British Heart Foundation says air pollution presents a 'major public health emergency' which must be urgently addressed by the new Government.
It is calling for World Health Organization (WHO) guidelines on particulate matter (PM) to be adopted in to UK law and met by 2030.
The call comes as the charity has launched a hard-hitting campaign, 'You're full of it', to highlight that we're all unwittingly inhaling dangerous levels of particulate matter air pollution in towns and cities across the UK every day.
It's estimated that up to 11,000 heart and circulatory disease deaths are attributable to particulate air pollution in the UK every year.
