Abstract: According to JJG1059-1999 Measurement Uncertainty and Results Indication, a mathematic model of uncertainty evaluation for the determination of polychorinated biphenyls (PCBs) in river crab by gas chromatography (GC) was established. The whole determination procedure was systematically investigated to analyze the sources of determination uncertainty. Meanwhile, the uncertainty of each variable was also evaluated and synthesized. The major affecting factors of GC determination uncertainty for PCBs in river crab were achieved.

Key words: gas chromatography (GC), river crab, polychorinated biphenyls (PCBs), uncertainty
