Characteristics of an immunoassay based wipe test for the detection of PCB
- Strategic Diagnostics Industries Inc., Newark, DE (United States)
The development of immunoassay based field screening methods for PCBs m soil has been a great benefit to site characterization and remediation efforts. These field screening methods can reduce project cost while improving the efficiency of site surveys and remediation efforts. Field screening techniques can also circumvent the long turnaround time of laboratory analysis by providing reliable on site results. On site wipe test technology for assessing PCB contamination on surfaces such as walls and floors of PCB storage facilities has been developed to compliment the D TECH{trademark} PCB Soil Test. This sampling technique can be used to monitor transformers for leaks and spills, or to evaluate a surface decontamination processes. The D TECH PCB Wipe Test is quick, cost effective, highly specific, and user friendly. The components of the immunoassay include PCB specific antibodies (Ab) covalently linked to small latex particles, a PCB analog which is covalently linked to alkaline phosphatase, and the free PCB from the surface. This assay has demonstrated 10 ug per 100 cm2 sensitivity to a broad spectrum of Aroclors. When correlating field trial data with EPA SW-846 Method 8080, a correlation coefficient of 85% and a slope of 0.9 is reported.
