Specific accumulation of organotin compounds in tissues of the rock shell, Thais clavigera

► We dissected the rock shell (Thais clavigera) to take out 15 or 16 tissues by sex. ► We determined tissue concentrations of TBT, TPT and their metabolites by GC-FPD. ► High concentrations of TBT and TPT were observed in the head ganglia. ► High tissue burdens of TBT and TPT were found in ovary.
