Influence of preexposure to sublethal levels of copper on Cu-64 uptake and distribution among tissues of the European eel ( Anguilla anguilla )
The effect of preexposure to copper was examined in European eels with respect to uptake and distribution of Cu-64 among tissues. Eels were exposed in freshwater to 8 and 64 mu g Cu . L(-1) for 0, 6 and 28 days before Cu-64 incubation. The accumulation of copper in gill, liver and muscle tissue was...
