Abstract: With the aid of GC-ECD (gas chromatography with electron capture detection), a micro matrix solid phase dispersion (MSPD) was used with LC-C18 as dispersant, Alumina-N as purificant and acetonitrile as eluting solvent to analyze residues of organochlorine pesticides (OCPs) in the meat of Carassius auratus. Results show that when 0.1g sample, 0.4g LC-C18 and 0.1g Alumina-N were used, the addition of 2.5mL acetonitrile created a better elution effect with recovery rate varying in the range of 73.0%-116.8% for all the three sample spiking levels (0.05, 0.25 and 0.50 mg?kg^-1) and relative standard deviation in the range of 1.6%-13.6%. The detection limits for all the fractions of organochlorine stayed below 3.5 μg?kg^-1.
