An investigation of the extraction recovery of butyltin species in sediment by supercritical fluid extraction (SFE) is presented. Satisfactory recoveries for TBT (93.5 f 3.7%) and DBT (91.5 f 3%) are achieved. The recovery for MBT from spiked sediment (62 + 5.1%) is the highest value so far achieved
