In this study, chlorinated cyclic hydrocarbon pesticides were extracted from water using a solvent mixture (hexane: dichloromethane), and their content was determined by GC-MS equipped with electron ionization (EI) and selected ion monitoring (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.
