Developments of techniques for measuring the quality of groundwaters : analysis of pesticides and metabolites etc

An attempt has been made to develop simple and effective analyses for a range of pesticides, pesticide mixtures, pesticide TEAPs and pesticide metabolites and to detail the practical aspects required for their accomplishment. All the methods are based essentially on two fundamental chromatographic techniques, i.e. high performance liquid chromatography (HPLC) and solid phase extraction (SPE). The former affords separation and quantification of the analytes, the latter provides pre-concentration so that trace levels of analytes may be determined. The aim is to provide sufficient information to permit a competent chromatographer to be able to generate analytical data on the concentrations of pesticides and their metabolites for use in studies and investigations that concern these environmentally significant species.
