## Abstract This paper describes the extraction of 20 organochlorine pesticides (OCPs) from water samples using solid‐phase microextraction (SPME). Three fused‐silica fibers coated or bonded with polydimethylsiloxane (PDMS) of different film thicknesses (20‐, 30‐, and 100‐μm) were evaluated. The ex
