ABSTRACT
Since the 1950s the organotin compound tributyltin (TBT) was intensively used in antifouling paints for marine vessels and it became of concern for the marine environment. Herein, we report on a study from 2015 on TBT and its metabolites monobutyltin (MBT) and dibutyltin (DBT) in sediments from the central Baltic Sea and a Baltic Sea coastal site with strong harbor activities (Warnemünde). Sublayers from a sediment core from the Arkona Basin were analyzed to investigate the long term organotin pressure for the Baltic Sea. For the central Baltic Sea total organotin (MBT+DBT+TBT) ranged from 100 to 500ng/g TOC with distinct areas of high organotin content probably due to historical inputs. For the coastal site total organotin ranged from 10,000 to 60,000ng/g TOC. MBT and DBT were the predominant organotin species detected. Overall, the data obtained indicate the progress of TBT degradation at the investigated sites.
