| Abstract: | The concentrations of PCBs in soil samples collected at rural and urban locations in Britain are reported. PCBs were detected in all samples analysed, within the range 2.3 to 444 μg kg−1 (ppb), with a mean concentration of 22.8 μg kg−1 and a median value of 7.2 μg kg−1. A distinct sub-group of samples has a range of 2.3 to 19.2 μg kg−1, with a mean of 7.5 μg kg−1 and a median value of 6.8 μg kg−1. These values are consistent with published data from other industrialised countries. Measurement was carried out using a two stage clean-up of soil extracts, with concentrated sulphuric acid and florisil, followed by gas chromatography and electron capture detection. |
