Abstract :In this study, chlorinated cyclic hydrocarbon pesticides were extracted from water using a solvent mixture insert ignore into journalissuearticles values(hexane: dichloromethane);, and their content was determined by GC-MS equipped with electron ionization insert ignore into journalissuearticles values(EI); and selected ion monitoring insert ignore into journalissuearticles values(SIM); methods. Additionally, the validation parameters for the method used were established. The recovery ratios of the spike levels varied between 82.7% and 95.4%. Heptachlor had the lowest recovery value, 82.7%, at a concentration of 1.480 µg/L, while Aldrin had the highest recovery value, 95.4%, at 11.200 µg/L. A satisfactory linearity was found for each pesticide at the four varied spike levels during the extraction procedure. Trans-Heptachlor > Heptachlor > trans-Chlordane > cis-Chlordane was the order in which the recovery efficiency of pesticides containing chlorine cyclo rings declined. Trans-Chlordane > trans-Heptachlor >Endosulfan > Dieldrin > Heptachlor > Aldrin > cis-Chlordane was followed by a decline in the relevant value of pesticides having two or more cyclic rings for the seven pesticides that made up the entire analysis period in this experiment a sufficient differentiation was made in around 18 minutes.
