| Abstract: | In order to evaluate effects of contaminants at high latitudes, the effects on scope for growth (SFG) were evaluated for both transplanted and resident blue mussel (Mytilus edulis L.) near large and small harbours in Iceland. Low SFG values were found for mussels at the mouth and in the inner part of the large Reykjavík harbour, which could be attributed to elevated levels of organotins and polyaromatic hydrocarbons. Mussels in smaller and/or less polluted harbours and sites off Reykjavík harbour only showed a slight reduction in SFG. No major effects were found at sites >3 km from the large harbour of Reykjavík. SFG provides valuable information on the effects of harbour pollutants in Iceland, in particular in areas of extensive shipping activity. The use of this biomarker on high latitude organisms is highly relevant due to extended oil exploration at higher latitudes. |
