In this study, 14 pesticides (captan, chlorothalonil, deltamethrin, dicloran, fenthion, folpet, iprodione, linuron, malathion, prometryn, prochloraz, procymidone, trichlorphon and trifluralin) were employed for developing a multiresidue method (MRM) using pressurized liquid extraction (PLE). In situ clean-up was achieved using matrix solid phase dispersion (MSPD), where Florisil, XAD-4, XAD-7 and C18 were tested as dispersing material for carrot samples. Dichloromethane, ethyl acetate and acetone were used as solvents in a PLE unit at 75 oC and 1,500 psi. Recovery was in the range of 70 to 133 %. Results obtained with wet carrots were not satisfactory, since most of the recovery values were below 70%. Determination coefficients of the analytical curves presented values between 0.9821 and 0.9970. Limits of detection (LOD) and quantification (LOQ) for the various components varied from 0.0024 to 0.1968 mg kg -1 , and 0.0072 to 0.5963 mg kg -1 , respectively.
