The analysis of polychlorinated biphenyls (PCBs) generally requires selectivity and sensitivity. Even after cleanup, PCBs are usually at ultratrace levels in field samples, mixed in with other halocarbons, hydrocarbons, lipids, etc. The levels of PCBs typically found in water, soil, tissue, food, biota, and other matrices of interest are in the parts per billion (ppb) range. Most current measurement techniques for PCBs require chromatographic separations and are not practical for routine analysis. There is a strong need to have rapid and simple techniques to screen for PCBs under field conditions. The use of field screening analysis allows rapid decisions in remedial actions and reduces the need for sample preparations and time- consuming laboratory analyses. Field screening techniques also reduce the cost of clean-up operations. This paper describes a simple screening technique based on room temperature phosphorescence (RTP) and provides an overview of both this analytical procedure to detect trace levels of PCBs in environmental samples.
