Abstract
Abstract
We have modified a standard capillary column gas chromatographic method (U.S. Environmental Protection Agency No. 505) for the determination of polychlorinated biphenyl (PCB) residues and applied the technique to mussels (Mytilus galloprovincialis) from Galicia, Spain. During the purification step, SepPak Florisil minicolumns are used instead of conventional columns. Method performance is good (limit of detection, 0.032 μg/kg; recovery, 99%; method precision as coefficient of variation among 10 samples, 2.5%), and compared with the standard method, less eluant is required and analysis is faster. The mean PCB content of 107 mussels collected from various points on the coast of Galicia was 113 μg/kg.
