SOLID-PHASE TECHNIQUES IN THE EXTRACTION OF PESTICIDES AND RELATED-COMPOUNDS FROM FOODS AND SOILS

The application of SPE technology to the isolation of pesticides and r elated compounds from food and soils has grown enormously in the last decade. Much of this growth has been due to the relative ease of sampl e handling and the wide range of solid supports currently available fo r a variety of applications. The aim of this review is to present the methods for solid phase extraction (SPE) of pesticide residues from so ils and foods. There are three main areas according to the type of app roach used to handle the sample: solid phase extraction, solid phase c lean-up (SPC), and matrix solid phase dispersion (MSPD). This review c overs milk products, fatty foods, fruits, vegetables, and soils. Solid phase materials are discussed in each case in terms of reversed bonde d-phase silica sorbents (C18, C-8, C2, etc.) and polar sorbents (alumi na, Florisil, and silica).
