The article analyzes the feasibility of using tributyltin (TBT)-contaminated harbor sludge for plant production and the influence of the plants so grown on TBT removal. Sediments dredged in May 2003 from the brackish waters of the port of Antwerp were investigated for soil texture, pH, electroconductivity, sodium, magnesium, potassium, calcium, ammonium, nitrate, total nitrogen, chloride, sulphur and the organotins TBT, DBT and MBT. For the top layer of the soil, the mean TBT concentration in samples from all vegetated plots was lower as compared to the unvegetated blanks. Barley turned out to be the optimal species, which grew very well despite the salinity of the dredged sediments. It an appreciable positive effect on TBT removal.
