The effect of copper on the heartrate and filtration rate of Mytilus edulis
Exposure of Mytilus edulis to dissolved copper led to a decrease in heart rate and filtration rate. After 4 days exposure to copper, the concentration of copper causing a 50% reduction in heart rate (EC50) was 0.17 ppm. After 5 days exposure to copper, the EC50 for filtration rate was only 0.002 ppm copper. Reductions in heart rate and filtration rate are not caused by valve or siphon closure.
