Applicant's summary and conclusion
- Conclusions:
- Very low concentrations of octyltins were detected in harbor water, but not in sediment, indicate a fast degradation of octyltins in sediment
- Executive summary:
In sea-water, apart from butyltins, octyltins were also detected . Tri-, di- and monooctyltin concentrations were measured and found to decrease in the order MOT > DOT > TOT in the inner harbour. However, in the outer harbour only mono- and dioctyltins were detected. The half-life of octyltins might be less than that of butyltins, because no sediment contained even a trace of octyltin residues, indicating that the degradation of octyltins might be faster in the water column and/or sediment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
