Long term monitoring of atmospheric mercury concentrations may provide direct evidence of temporal trends, because of an atmospheric residence time of about 1 year (Slemr et al., 1985; Lindqvist and Rodhe, 1985). Slemr (1996) has reviewed the few existing publications on long term monitoring of mercury starting with early data published by Stock and Cucuel (1934) and concludes, that the reconstruction of trends by combining data of these reports is hardly possible for several reasons:1.the quality of reported total gaseous mercury (TGM) concentration measurements is mostly unknown,2.mercury monitoring has only rarely been accompanied by supporting measurements of chemical tracers that will allow the elimination of locally influenced data,3.most of the reported measurements of TGM in air are very limited in time and space.Based on these uncertainties and the systematic gaps in previous knowledge on mercury, Fitzgerald (1995) has proclaimed the need for a global atmospheric mercury monitoring network.Continuous measurements of total gaseous mercury (TGM) concentrations with 15 minutes time resolution have been carried out at the atmospheric research station at Mace Head between September 1995 and September 2001. Monitoring work is continuing on a contractual basis for the Irish Environmental Protection Agency since October 2001. Mace Head was one of the first research stations (together with a Canadian site in the high Arctic (Alert, Nunavut, NWT)), generating highly time resolved concentration measurements of TGM on a routine basis (Schroeder et al., 2001).
