Abstract
The flux of tributyltin(TBT) from contaminated sediment was estimated using a him transfer model. Mass transfer coefficient was around 10(-6 ) (m/sec) and showed diversity according to the turbulence of overlayi ng water. Release to the overlaying water and degradation in the sedim ent itself were compared in regard to contributions to removal of TBT from sediment. Releases are greater when sediment has a large porosity , whereas degradation tends to contribute more with rather smaller por osity.
