The occurrence and current status of butyltin and phenyltin compounds were investigated in sediments collected from the Arakawa and Sumida Rivers and Tokyo Bay in 2000. A series of butyltin and phenyltin compounds, including monobutyltin (MBT), dibutyltin (DBT), tributyltin (TBT), monophenyltin (MPT), diphenyltin (DPT), and triphenyltin (TPT) was detected by gas chromatography-mass spectrometry (GC-MS). The total concentrations of the butyltin (MBT + DBT + TBT) and phenyltin (MPT + DPT + TPT) compounds ranged from 25.7 to 116 and from non-detectable levels to 22.4 ng g^<-1> (as Sn), respectively. The concentrations of the organotin (OT) compounds in sediments were relatively lower than those of the samples collected in 1984. OT compounds accounted for 1-24% (as Sn) of total Sn in the sediments. Among the OT compounds investigated, MBT was the most prevalent in the sediments.
