Contaminants in marine biota 1990 monitoring programmeNixon, E R; McLaughlin, D; Boelens, R G; O'Sullivan, G (Department of the Marine, 1991)In 1990, samples of fish from commercial catches landed in Ireland, and fish and shellfish collected at Irish coastal sites, were analysed in accordance with the requirements of the Joint Monitoring Programme (JMP) of the Oslo and Paris Commissions (OSPARCOM). The methodologies employed were consistent with JMP Purpose A: Significance to human health, and JMP Purpose C: Existing geographical distributions. The levels of heavy metals and chlorinated hydrocarbon compounds were generally low: well below the internationally accepted levels for protection of human health, and below the levels known to be of significance to marine life. Higher than Irish average levels were found in areas such as Dublin Bay, Cork Harbour, Mornington on the river Boyne, and the Barrow and Rogerstown Estuaries. These are all adjacent to densely populated and industrialised catchments and coasts. There were no cases of serious contamination.
Levels of metals and organic contaminants in mussels Mytilus edulis from Cork Harbour - 1989Boelens, R G; Nixon, E R; McLaughlin, D (Department of the Marine, 1990-07)This study of contaminants in mussels from outer Cork Harbour (Buoy no. 8) has shown that the levels of selected metals and organochlorine substances are generally low and at the lower end of the ranges measured in recent surveys of mussel populations at other European coastal sites.
