A new report claims that seventy lives a year could be saved in Cork if international guidelines on air pollution were adopted.
A major all-island assessment discovered that around 2,600 premature deaths are caused by air pollution every year.
The study was commissioned by the Irish Heart Foundation and British Heart Foundation Northern Ireland and compiled by experts from Queen's University Belfast and the Technological University of Dublin.
The report found the biggest risk to life from air pollution is heart disease.
In Cork city and county, the data shows that 200 premature deaths a year are linked to dirty air - of which 85 deaths are caused by heart disease resulting from air pollution.
The levels of air pollution in Cork caused by the burning of solid fuels is 62% above the World Health Organisation's recommendation.
The Irish and Northern Irish heart charities are calling on both governments to improve air quality across the whole island.
