## Abstract A new method of dispersive liquid‐liquid microextraction (DLLME) combined with GC‐electron capture detection (GC‐ECD) was proposed for the extraction and determination of four polychlorinated biphenyls (PCBs) congeners in fish samples. Acetone was used as extraction solvent for the extr
