Supercritical fluid extraction (SFE) was optimized for the application to the extraction of several organochlorine pesticides in aquatic biological samples. SFE required 2 ml/min for supercritical fluid carbon dioxide flow rate, 0.70 g/ml for density (50 °C for temperature and 151 bar for pressure), and 7 % methanol for modifier. The extraction was completed for 40 min. After SFE, it was possible to be analyzed with GC/MS after clean-up with Florisil, packed in Pasteur pipette. From the comparison with ultrasonic extraction and SFE to mussels which were exposed to organochlorine pesticides, SFE seems to be applicable for the analysis of these pesticides in aquatic biological samples.
