Analysis of soil and dust samples for polychlorinated biphenyls by enzyme-linked immunosorbent assay (ELISA)

An inhibition enzyme-linked immunosorbent assay (ELISA) was used to determine polychlorinated biphenyls (PCBs) in house dust and soil. Soil and house dust samples were analyzed for PCB by both gas chromatography/electron capture detection (GC/ECD) and ELISA methods. A correlation coefficient of 0.91 was obtained for the 41 soil samples. The correlation between the GC/ECD and the ELISA methods for the 10 house dust samples was not as good as that for the soil samples.
