Date of Publication
Studies were done to ascertain the levels of PCBs in soil, water and sediments in some urban and rural areas in Jamaica. All the soil samples collected contained less than 10 ppm PCB and PCB was found only in soil samples which were collected from sites where transformers were stored or are in use. The mean concentrations of PCBs in the urban and rural soil samples were 0.7 and 0.2 mg/kg respectively with over 80% of the samples containing less than 2.0 mg/kg. The median concentration for the urban soil samples was 1.4 mg/kg while that for the rural was less than 0.1 mg/kg. The concentration of PCBs was measured either by using a gas chromatograph attached to an electron capture detector or a mass spectrophotometric detector.....
