Abstract :

Dangerous effects of pesticides on human and environmental health,especially their roleinfood chains; are the most important reasons to doing this study. Hence, it is necessary to investigatethese compoundsinthe environment, foodandlivingbody.  InthisStudysinceSeptamber 2010 to March 2011,sugar beet samples from five areasofIsfahan province had been collected (Isfahan, Borkhar, Semirom, Golpayegan and Fereydan cities). Samples analyzed by chromatographic methods to determine the residue of two pesticide (Chloropyrifus and Deltamethrin) which had been used as usual pesticides in areas that are the main sugar beets producers for sugar factories in Isfahan province.In this study, High Performance Thin Layer Chromatography (HPTLC) was used to determine Chloropyrifus andDeltamethrinresidues in sugar beets Thehighest amount ofpesticide residue belongs to Deltamethrin in Semirom andthe lowest one was observedinGolpayegan. The amounts of Deltamethrinresidueinthe collected sugar beets from Semiromwere equal or higherthanthe maximumresiduelimitation (MRL)(0.05mg/kg). The amounts ofChloropyrifus residueinthe sugar beets any areas not were equal or higherthanthe maximumresiduelimitation (MRL) (0.01mg/kg) andThehighest amount ofpesticide residue belongs to Chloropyrifus in Borkhar andthe lowest one was observedin two areas ofIsfahan and Golpayegan.
