Collection efficiencies of organochlorine pesticides by supercritical fluid extraction(SFE) was
investigated to develop a simple, fast and inexpensive extraction method. Standard organochlorine pesticides mixture(SOPM, no water) showed no evidence of metering valve plugging in contrast to the plugging associated with SFE of fish tissues(wet sample). Maximum percent recovery of SOPM was obtained at bar by collecting the extract within 3 min through the metering valve without heating into a capped screw-top tube half filled with solid CO_(2) Recovery of SOPM itself shwes 98.3% while recovery of that spiker in fish tissue 85.6%.
