Polychlorinated Biphenyls (PCBs)

Polychlorinated biphenyls are a class of organic compounds with one to 10 chlorine atoms attached to a pair of bonded benzene rings. PCBs were widely used for many applications, especially as dielectric fluids in transformers, capacitors, and coolants. Due to PCB's toxicity and classification as a persistent organic pollutant, PCB production was banned by the United States Congress in 1979 and by the Stockholm Convention on Persistent Organic Pollutants in 2001.

PCBs have low water solubility and are largely chemically inert, making them extremely resistant to oxidation. These properties allow PCBs (commonly detected using EPA Method 8082) to resist environmental degradation so they tend to accumulate in soil and river sediment. This method determines the concentrations of various PCB congeners and Aroclors in extracts from solid and liquid matrices, including food products using gas chromatography with electron capture detectors (ECD). This new application speeds sample preparation by combining multiple processes into one. This is a first for analysis of PCBs.

Toxic Reports performs a number of test procedures for the presence of PCBs in oils, waste water, solids, sediments and tissues. When analyzing for PCBs the three main types of instruments that are used are, gas chromatography-electron capture detection (GC-ECD), gas chromatography (GC) with low resolution, electron ionization mass spectrometry (MS), and the high resolution gas chromatography coupled with high resolution mass spectrometry HRGC/HRMS.

Our lab offers all of the mentioned instrumentation.
