Appearance of EC Spectra

especially when combined with GC-MS, is widespread in monitoring environmental pollutants such as toxaphene, [72] dioxins, [74,79,82,84] pesticides, [79] halogenated metabolites, [71] DNA adducts, [78] explosives, [66,85,86] and others. [68,69,87,88] 

the analyte is introduced into the ion source the same way as described for El, i.e., via direct insertion probe (DIP), direct exposure probe (DEP), gas chromatograph (GC), or reservoir inlet (Chap. 5.3). 

especially when combined with GC-MS, is commomly used in the monitoring of environmental pollutants such as dioxins [90,93,95], pesticides [90], halo-genated metabolites [81], DNA adducts [89], explosives [75,96,97], and others [78,79,98,99].
