An important goal in the field of analytical chemistry is to achieve continual improvement in the analysis of persistent toxic pollutants. Halogenated organic compounds represent an important group of pollutants. They are used in a wide variety of applications such as flame retardants, fire suppressants, heat-transfer agents, surfactants and pesticides, mainly because of their chemical inertness and stability. As a result of this stability, many of these halogenated organic compounds are persistent in the environment, toxic and bioaccumulative in the food chain, and are consequently associated with adverse effects on human health and the environment.
