A commercial colorimetric field screening kit for the detection of polychlorinated biphenyls (PCBs) is compared to instrumental thermal neutron activation analysis as a screening tool in a variety of oil matrices. The precision of these two methods was compared to an accepted method of analysis, gas chromatography with electron capture detection, and interferences of each screening technique were investigated. The colorimetric test was shown to be less reliable and more prone to interferences than neutron activation analysis. The advantages and limitations of each method are discussed.
