Nontargeted Analysis of Persistent Organic Pollutants by Mass Spectrometry and GC×GC

Identification of persistent organic pollutants (POPs) remains one of the most challenging aspects of environmental chemistry. This is partly the result of a dearth of toxicological data, genuine analytical standards, adequate chemical libraries and analytical methodologies necessary to distinguish suspected POPs from among the c. 100,000 chemicals used in industry and commerce. One approach is to tailor detection methods such that POPs can be …
