Explosives produced both for military and civilian use are important pollutants of soils and aquatic systems in the vicinity of places where they are produced, stored or used. Many of them are classified as toxic by the US-EPA and other environmental agencies.
Because of the easy electrochemical reducibility of nitro group, voltammetric and amperometric methods are frequently used for their determination which are discussed in this chapter. The various electrode materials in use for the determination of explosives as well as the analytical approaches including microfluidic devices are reviewed.
