Routes of TBT uptake in the clam Ruditapes decussatus. I. Water and sediments as vectors of TBT uptake
This study assesses the relative importance of water and sediments as vectors of TBT uptake in the sediment-dwelling suspension feeder, Ruditapes decussatus. Accumulation of TBT was determined in R, decussatus exposed for 60 days to moderately high but environmentally realistic levels of TBT in wate...
