Due their physical end chemical properties, organochlorine pesticides (OCPs) have been occured the contamination the environment and food chain. The consume of this products at low concentration dose represent a potential hazards to human health. The QuEChERS method was adjusted and used for the determination of 12 organochlorine pesticides (α- BHC, β - BHC, heptachlor, dicofol, endosulfan lacton, OP DDD, α - endosulfan, OP DDE, PP DDE, β - endosulfan, PP DDD, endosulfan sulfate) residues in 36 strawberries samples from three markets of the Piracicaba/ Sao Paulo – Brazil, during the period of October 2010 until September 2011. The method involved extraction with ethyl acetate, solid–liquid partition with MgSO4 and CH3COONa followed by dSPE clean up with PSA sorbent. Analyses were carried out with GC–µECD equipment. A HP-5 30 m x 0.32mm x 0.25 µm column was used. The method wa...
