Resource or Project Abstract

Metals occur naturally in seawater at low concentrations and some act as essential micronutrients for marine biota, but they become toxic when absorbed or ingested by plants and animals at high concentrations. Despite some recent research on metal contents in seaweeds from Ireland, few data exist regarding the metal contents in Irish coastal and transitional waters. The recent Discussion Document on a National Environmental Monitoring Programme for Transitional, Coastal and Marine Waters by the Environmental Protection Agency of Ireland proposes the inclusion of seaweeds in an extended assessment of metal concentrations future monitoring programs in Ireland and recommends the monitoring of hazardous substances and contaminants, including metals, by using biomonitoring organisms, such as shellfish and seaweeds. Currently no standardised monitoring protocol exists in Ireland, although some limited biomonitoring of metals using shellfish has been conducted. In this 3-year project, we observed seasonal, spatial and inter-site variations in phenol and metal (copper, zinc, cadmium, chromium) contents and in phenol composition in the ecologically and economically most important seaweeds in Ireland, Ascophyllum nodosum and Fucus vesiculosus, demonstrating their suitability as biomonitors of metal contamination. The experimental approach taken in this project established a quantitative link between physiological responses in intertidal brown seaweeds and phenol production, composition, exudation and their potential to bind metals under natural environmental conditions. The effect of copper enrichment and its interaction with salinity, and the effect of iron and zinc contamination were closely investigated. However, neither the intra-cellular phenol content of the seaweed, nor the phenol exudation could be used as biomarkers of metal contamination, whereas the cell-wall phenol content of brown seaweeds seems promising but needs further investigation. This project has produced data on the contaminative status of selected Irish coastal and transitional waters, including sites of active seaweed harvesting by the Irish seaweed industry. Finally some recommendations are proposed for the sampling methodology when using seaweeds as biomonitors of metal contamination, and some general comments on the utilisation of a series of biomonitors (seaweed, animal filter-feeder such as mussel, sediment) to characterise the metal contamination of a site in more detail.

Geographical and Spatial Information Related To This Resource

Description of Geographical Characteristics of This Project or Dataset
Ballyconneely (5323.42N 1002.47W) is a marine, moderately sheltered site, situated within the Connemara and facing the Atlantic Ocean with little anthropogenic impact. A. nodosum is harvested on this site for the Irish seaweed industry. Oranmore (5316.15N 857.22W), Kinvara (5308.28N 855.44W) and Finavara (5309.25N 906.58W) are all situated within a Special Protection Area (SPA; Inner Galway Bay; SI No 349/1994) but they exhibit very different environment conditions. Oranmore and Kinvara are located in the inner part of the Bay and present higher nutrient enrichment than Finavara and contain mud on the lowest part of the shore. At Kinvara, a large fresh- ground- water river is emerging close to the castle and the sampling site resulting in dramatic changes of the salinity for the seaweed over a tide cycle: in few hours, this salinity varies between 32.6 at high tide down to 0.5 at low tide. On the other hand, Finavara is a typical marine site. In the industrialized Shannon Estuary, only Ringmoylan (5240.09N 852.42W) is part of a SPA (River Shannon and River Fergus Estuaries; SI No 210/1997). This site is located in the inner part of the Estuary. Foynes (5236.23N 909.26W) is situated in the middle part of the Estuary. At the entrance of the Estuary, Beal Point (5234.77N 937.34W) and Carrig Island (5234.35N 930.28W) are grouped as one site due to the absence of A. nodosum on Beal Point shore. The closest site in the estuary containing this seaweed species was Carrig Island. Cobh (5151.41N 819.57W) is situated in the estuary of Cork Harbour, close to Passage West. It is influenced by anthropogenic impacts. The two sites in France were located in the Bay of Brest, Le Dellec (4821.05N 434.11W) on the outer part of the Bay and Moulin Blanc (4823.47N 425.24W) on the inner part of the Bay close to the nutrient enriched River Elorn and to the military and commercial harbours. At both sites only A. nodosum was present.
