The increasingly widespread application of pesticides causes that larger amounts of them are entering the environment. Their presence in sources of drinking water, essential to life, is a particular danger. For these reasons it is important to monitor and analyse pesticide residues in the environment. The analysis of environmental samples for the presence of pesticides is very difficult. Firstly, the processes involved in sample preparation are labour-intensive, time-consuming and may be a source of additional contaminations and errors. Secondly, the low concentration level of analytes and matrix complexity cause many problems as well. That is why a special analytical procedure is required in this respect, one that enables a large number of compounds to be determined in a single analytical run. In the case of determination of pesticides, compounds have to be isolated from a complex matrix and then preconcentrated prior to the final determination. This kind of analyses are recommended by the European Union. That is why studies are going on into the improvement of existing techniques and the development of new ones, which would enable pesticides from different chemical classes to be reliably and reproducibly determined at the same time in a quick, simple, cheap, effective and environmentally friendly manner. This review examines the most commonly used techniques for extracting and determining modern used pesticides, and discusses the analytical problems arising at each stage of the analytical procedure.
