Pesticides has become an essential part of our life and have entered and bioaccumulated in water, air, soil ecosystem, and food. However, the majority of the pesticides are not biodegradable and eco-friendly, and the accumulation of them in food and the ecosystem could constitute a serious risk to human and environmental health. It is critical to understand pesticides' identities and level of residues present in environment and food. Robust analytical techniques that offer easy, fast, and reliable extraction of multiresidue pesticides in water, soil and food with matrix interference-free quantification are necessary for proper risk assessment. Although various methods have been reported for pesticides extraction in food and environment samples, dispersive solid-phase extraction (d-SPE) has become the most popular sample preparation method for pesticides analysis today. Multiresidue pesticides extraction in food and environmental sample using a novel d-SPE method, dispersive pipette extraction (DPX), is described step-by-step in this chapter.
