Abstract
Microwave extraction and ultrasonication of dioxin-like polpchlorobiphenyls (PCBs) from sediment samples were investigated. After separation of dioxin -like PCBs from a sample matrix on an acidic-alkaline silica gel column, di oxin-like PCBs were determined by GC-ECD, using dual capillary columns. Rec overies of dioxin-like PCBs in Fiver sediment samples exceeded 80 % by both extraction techniques. Toxic equivalency factors and their use for the PCB congeners investigated were applied.
