Polychlorinated diphenyl ethers (PCDE), also called bis(chlorophenyl) ethers and chlorodiphenyl oxides, are neutral aromatic compounds which resemble structurally polychlorinated biphenyls (PCB), except that one oxygen atom connects the phenyl rings. The empirical formula of the PCDEs is C12H10 nClnO, where n = 1-10. The structural formula of the PCDEs is given in Fig. 1.

OSHA regulates polychlorinated biphenyls under the Hazard Communication Standard and as chemical hazards in laboratories. OSHA s PEL on an 8-hour TWA for chlorodiphenyls containing 42% chlorine is 1 mg/m. Its PEL on chlorobiphenyls containing 54% chlorine is 0.5 mg/m. These standards are based on the toxic effects other than cancer. NIOSH recommends the exposure to PCBs be controlled to the lowest feasible concentration.

Several imrelated groups of chlorinated aromatic compounds can be considered together based on their similar composition and toxicity polychlorinated biphenyl congeners (PCBs), dioxins and furans, chlor-onaphthalenes, and chlorodiphenyl ethers (see Figure 13.1). Most of these compoimds are included in the Stockholm Convention Agreements of 2001 and 2008, and their production is reduced or eliminated in most parts of the world. However, the compoimds are highly persistent in the environment and exhibit other properties associated with POPs. Because chlorinated aromatic compoimds are nonpolar and stable at elevated temperature, gas chromatography is the preferred approach for analysis. Numerous reviews have been published that detail GC methods of analysis for PCBs, dioxins, and other chlorinated aromatic compounds in environmental samples [6,9,54].
