A new study of air quality has found pollution levels are higher than expected in Tralee. The Environmental Protection Agency carried out the research in Tralee, Killarney, Navan and Letterkenny from 2011 to 2012. The agency carried out the study as there is not regular air quality monitoring in those towns. Tralee, which has a smoky coal ban in place, along with Letterkenny had poorer air quality than Dublin city over the period of the study. While no legal limits were breached, levels the towns were above World Health Organisation guidelines. Killarney came in within the recommended guidelines. Meanwhile, the Asthma Society is holding a public information evening this evening at 7.30 in Killarney to discuss air quality in the county. The event is taking place in the Killarney Avenue Hotel.
