The findings are detailed in the latest report from the Environmental Protection Agency
Data from the EPA shows high readings of air pollution were also recorded in Tralee, Ennis and Enniscorthy while the air pollution recorded in Dublin at the weekend showed levels not seen in three decades
The report has prompted a scientist based in Cork to warn that people are being exposed to dangerous levels of pollution due to the burning of solid fuels
Professor John Wenger is from the Centre for Research into Atmospheric Chemistry at UCC, which studies the data.
He says exposure to air pollution leads to over 1,200 premature deaths in Ireland every year:
"Exposure to air pollution affects the heart, affects the lungs and we know also now it effects the brain as well. It's actually been linked with increased incidence of Alzheimer's and Parkinson's disease, for example. So it affects the whole body because the particles that are generated from burning solid fuels can enter the body and move around the body and target certain organs."
