The distribution of organotin compounds in bivalves collected from Vietnam, Thailand and Indonesia was studied in order to examine the present status of contamination on marine environment. The bivalves such as clams Meretrix spp., green mussels Perna viridis, and arkshells Anadara granosa and A. antiquata were purchased at each local market or collected from each coast. Six organotin compounds, monobutyltin (MBT), dibutyltin (DBT), tributyltin (TBT), monophenyltin (MPT), diphenyltin (DPT) and triphenyltin (TPT) were analyzed in these samples using GC-MS. Concentrations of TBT in bivalves specimens collected from Vietnam, Thailand and Indonesia were in the range of 0.37-56 ngg^<-1> wet wt., 0.83-16 ngg^<-1> wet wt. and 9.737 ngg^<-1> wet wt., respectively. Among 12 Vietnamese sites, average concentration of TBT (47 ngg^<-1> wet wt.) in clams from Cua Luc was the highest level, and the ratio of TBT to ΣBTs in this site was 86%. As Cua Luc is an industrial town having large international trading port, continuous input of TBT from vessels might be indicated. Concentrations of MPT in clams from Vietnam ranged from 0.16 to 11 ngg^<-1> wet wt., and those of DPT and TPT in clams from Vietnam and MPT, DPT and TPT in bivalves from Thailand and Indonesia were close to the detection limit. The present study indicated that organotin compounds in bivalves from Vietnam, Thailand and Indonesia were fallen in the range of levels reported throughout the world.
