Resource or Project Abstract

Avariety of air pollutants are causing considerable concern as a result of their known or suspected harmful effects on human health and the environment. Field measurements show us that the atmosphere always contains a significant concentration of particulate matter (up to 108 particles per cubic centimetre). These particles are thought to carry surface adsorbed carcinogenic compounds such as polycyclic aromatic hydrocarbons (PAHs), but little is known about their exact chemical composition. It is, of course, expected that they will consist of inorganic elements, ions, trace metals, elemental carbon, organic compounds and water in a variety of proportions, depending on their sources. Of particular interest are particles that have an aerodynamic diameter of less than 10-5 metre (PM10 ), since they are able to penetrate deep into the lungs and are known to have adverse effects on human health. PM10 are produced from incomplete combustion processes, industry, construction and natural sources, and, in cities, the principal source is road traffic emissions, particularly from diesel vehicles.

This project, which is the first of its kind in Ireland, involves the characterisation of the processes that produce particles present in urban air. There are five major sampling sites operated by Dublin City Council, Cork City Council, and researchers at the National University of Ireland Galway. Automated 24-hour aerosol samplers have been installed at each of the sites since July 2001. Particles are collected on filters and sent to the partner laboratories for analysis. The University of Birmingham measures the amounts of elemental carbon and selected ions present in the particles. Analysis of metals and polycyclic aromatic hydrocarbons by inductively coupled plasma ? atomic emission spectroscopy (ICP-AES) and gas chromatography ? mass spectroscopy (GC-MS) respectively, are performed at University College Cork.

Geographical and Spatial Information Related To This Resource

Description of Geographical Characteristics of This Project or Dataset
Five sampling locations were selected to represent typical urban, rural and coastal environments . Two urban stations (roadside and background) were established in Dublin, and one in Cork (roadside). A rural site was established in central Ireland and an east coast site was set up to sample arriving air masses crossing the Irish Sea.Site A (53° 21' N, 6° 16' W) is an urban roadside site situated at College Street, Dublin. Site B (53° 21' N, 6° 17' W) is an urban background/centre Coleraine Street, Dublin Site C (52° 58' N, 5° 56' W) is a coastal site at Wicklow Head on the East Coast. The rural site (53° 21' 6'' N, 8° 18' 30'' W) is located in central Ireland. Site E in Cork (51° 53' 45'' N, 8° 27' 57'' W) a link road between Anglesea Street and the south city link road
