摘要: The contemporary state of the determination pesticide residues and some their transformation products is reviewed. review covers chromatographic herbicides, insecticides important fungicide toxic (substituted anilines, chlorophenols, ethylenethiourea) in various types water samples. Advantages drawbacks gas liquid chromatography this type analysis are discussed. emphasis placed on multi-residue analytical methods with required limit quantification (LOQ < 0.1 μg l−1) recovery. Various aspects isolation, preconcentration clean-up residue extracts from samples discussed (liquid-liquid extraction, liquid-solid extraction supercritical fluid extraction). characteristics a modern method for summarized trends development GC LC
