Cypermethrin was simultaneously extracted by MSPD and determined by GC-ECD. The main parameters affecting extraction yield and selectivity, such as the type of solid adsorbent material, choice of elution solvents and their volume, were investigated to obtain interference-free extracts and quantitative cypermethrin recovery. Fortified recoveries in muscle, liver, and gill samples ranged from 84.9% to 106.1%, and relative standard deviations were <8% with fortification levels of 0.05-1mgkg−1. Detection limits were 1.4-2.1μgkg−1, and quantitation limits were 5.8-7.8μgkg−1. The proposed method was successfully applied to determination of cypermethrin in fish tissue samples.
