This review intricately examines the crucial role of environmentally friendly solvents over the past 20 years in mitigating secondary environmental pollution during the pre-concentration of pesticides in aqueous and food matrices. Ionic liquids, renowned for their environmental compatibility, are widely employed in pesticide analysis due to their versatile physico-chemical properties. The review provides a thorough examination of the utilisation of ionic liquids in the process of pre-concentrating pesticides in both food and aqueous samples. Additionally, the paper explores the significance of deep eutectic solvents, formed by combining hydrogen bond donors and acceptors, in the pre-concentration of pesticides, providing a comprehensive overview of their applications. The study delves into the role of supramolecular solvents, characterised by three-dimensional amphiphilic aggregates, and switchable solvents, recognised for reducing chemical consumption, in pesticide pre-concentration. The review also discusses future prospects and difficulties linked to the utilisation of eco-friendly solvents.
