Sudden air pollution spikes in the UK are causing hundreds of other heart attacks, strokes and acute asthma attacks these days.
A The King's College London team studied data from London, Birmingham, Bristol, Derby, Liverpool, Manchester, Nottingham, Oxford and Southampton.
On days when pollutant levels were in the upper half of the annual range, 1
The head of NHS England, Simon Stevens, said it was a "health emergency".
The number is based on ambulance call data and does not take into account the heart attacks that have already occurred in the hospital.
This indicates Significant short-term health risks from air pollution include nearly 500,000 premature deaths in Europe each year.
On days with a high degree of pollution, an average of 231 were added in the nine cities. Heather Walton of King's London Environmental Research Group focused air pollution reduction efforts primarily on life-cycle related impacts.
"Health studies, however, show clear links with a much wider range of health effects," she added.
In London, days of high pollution caused an average of 87 additional cardiac arrests, 144 additional strokes and 74 children and 33 adults who ended up with asthma in the hospital.
Birmingham recorded 12 more cases of cardiac arrest, 27 additional strokes and 26 more in asthma.
Bristol, Liverpool, Manchester, Nottingham, Oxford, and Southampton experienced two to six more heart attacks outside the hospital and up to 14 additional hospital admissions for stroke and asthma on days of high environmental impact.
Only in Derby was no increase recorded.
& # 39; Preventable deaths & # 39;
The long-term risks associated with high levels of environmental impact include subdued and low birthweight birth rates.
King's studies also suggest that a one-fifth reduction in air pollution would reduce the incidence of lung cancer by 5-7% in the nine cities studied.
Mr. Stevens said, "It is clear that the climate emergency is indeed a health emergency.
" Since these preventable deaths are now occurring – not 2025 or 2050 – we must now act together. "
The numbers were released before Wednesday's International Clean Air Summit on Wednesday by the Mayor of London, Sadiq, Khan and the UK100 Local Government Network.
UK100 Director Polly Billington said: "The local government needs additional powers and resources to address this public health crisis. "
The Department of the Environment, Food and Rural Affairs stated this to be" Immediate Action to Improve Air Quality and Combat Air Pollution "and to Introduce New Legislation" to Strengthen Local Authority to Combat the main source of air pollution ".
