title: Toxaphene levels in salmon (Salmo salar) from the Baltic Sea.
abstract: Three toxaphene congeners have been determined in salmon from the Swedish coastal environment using both supercritical fluid (SFE) and the traditional liquid/liquid extractions. The levels obtained using a modifier-free SFE technique, followed by group separation on a silica gel column, were by far much lower than concentrations obtained by SFE with a modifier or liquid/liquid extraction. The mean concentrations on fresh weight basis using a liquid/liquid extraction technique were 5.87, 8.70 and 1.59 microg/kg for CHBs 26, 50 and 62, respectively. There was a plausible relationship between the various fishing sites and the toxaphene levels.
