Polychlorinated Biphenyls
PCBs are synthetic and produced either as a singular congener, as a homogeneous group or as a mixture. Polychlorinated biphenyls (PCBs) are a family of 209 congeners of structurally similar organic chemicals, ranging from oily liquids to waxy solids. Some PCB congeners are dioxin-like and can similarly be toxic and non-toxic. One dioxin-like PCB is 3,4,4',5-Tetrachlorobiphenyl.
Reporting Limits – EPA Method 1668A: 0.2ppt for aqueous, 10ppt for solids, and 200pg/sample for air.
Additional congeners up to and including all 209, as well as total homologs can be reported. Please contact laboratory concerning availability and their typical reporting limits.
