, homogenization, extraction, cleanup, concentration and quantitation. GC, MS, LC/MS methods are used in detection. Efforts are on to develop cost effective mobile mini lab devices to conduct analysis in the field. Presently QuECHERS method is used for sample preparation followed by automated GC/MS and LC MS-MS analysis (Lehotay and Mastovska, 2005). Other contaminants like polyaromatic compounds (PACs) are analysed using High Resolution Gas Chromatography (HRGC) fast Gas Chromatography (GC) and
