Recent developments in the use of polarography and voltammetry at mercury electrodes in environmental analysis are reviewed and their combination with preliminary separation and pre-concentration using liquid or solid phase extraction is discussed. Attention is focused on ecotoxic nitrated polycyclic aromatic hydrocarbons, heterocyclic compounds, and pesticides. Advantages and limitations of mercury electrodes are critically evaluated and some recent applications of these techniques developed in our laboratory are given.
