This chapter will deal with recent results regarding voltammetric and amperometric determinations of micromolar and submicromolar concentrations of various environmentally important biologically active inorganic and organic substances in drinking water using non-traditional types of electrodes based on solid and paste amalgams, which can be environmentally friendly alternatives to mercury electrodes. Attention will be paid to polished and mercury meniscus modified solid amalgam electrodes (SAE), to silver solid amalgam composite electrodes and to amalgam paste electrodes either in batch analysis or in flow liquid systems (especially HPLC or FIA with electrochemical detection). Both polished and mercury meniscus modified silver solid amalgam electrodes (AgSAE) can be used in voltammetric and amperometric analysis of drinking water as an alternative to a hanging mercury drop electrode (HMDE). Other solid amalgam electrodes (e.g., CuSAE, AuSAE) are convenient for specific purposes, where properties of the metal, of which the solid amalgam consists, are employed. Silver solid amalgam composite electrodes, prepared from silver amalgam powder and epoxy resin, proved experimentally to be a suitable, reliable and environmentally friendly substitute for the hanging mercury drop electrode in electrochemical analyses. Amalgam paste electrodes based either on powdered amalgam mixed with a suitable organic pasting liquid or on amalgam paste can be used as nontoxic sensors with easily renewable surface and as a substitute of disposable electrodes. The review will concentrate on our own results in the context of the general development in the field.
