Abstract

In this, study, an analytical method was optimized for detecting dioxin-like PCBs in fish and shellfish. Hera, homogenized samples were extracted using an accelerated solvent extraction (ASE) system with 33 mL ceel sixe. Multilayer column choromatography, which consisted of actidic, basic, and neutral silica gels, was used for the clen up of the extracts. The instrumental analysis was executed by HRGC/HRMS to a resolution od 10,000 using 4 window multiple ion detection (MID) mode. For the results, the average recoveries ranged from 94.1 to 104.1% (±8.4) and the limit of detection was approximately 0.1 pg/g at S/N ratio >3. Finally, the detected concentration of dioxi-like PCBs for fish shellfish were in the rang of 0.030-1.836 pg TEQ/g.
