The effect of pollution on scope for growth of the mussel ( Mytilus edulis L.) in Iceland

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...

Description
Summary: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 Reykjavı́k harbour, which could be attributed to elevated levels of organotins and polyaromatic hydrocarbons. Mussels in smaller and/or less polluted harbours and sites off Reykjavı́k harbour only showed a slight reduction in SFG. No major effects were found at sites >3 km from the large harbour of Reykjavı́k. 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.
