This project involves conducting field measurements of particulate matter in and around Cork City; developing methods for the extraction and speciation of the organic fraction; performing chemical analysis on the organic fraction; developing toxicological tests that relate to the organic fraction of PM2.5 and identifying suitable organic markers for source apportionment modelling.

A high volume cascade impactor was deployed during 2005/2006 to collect PM at several sampling locations, including a road-side urban location at Old Station Road in Cork city centre, background urban site at Heatherton Park and a background rural site in Innishcarra (County Cork).

The first two years of research has been mainly focused on the identification of Polycyclic Aromatic Hydrocarbons (PAHs) which are toxic pollutants (including a probable human carcinogen Benzo(A)Pyrene); alkanes which are commonly deployed as markers in the source apportionment of PM and quinones which have been identified as reactive species that trigger toxicological events.
