Methodological aspects of sample preparation for the determination of carbamate residues: a review

Abstract

This review covers recent developments in sample preparations and analytical techniques for determination of residues of carbamate pesticides. Special attention is paid to the newly established microextraction techniques, including cloud-point extraction, dispersive liquid-liquid microextraction, and ultrasound-assisted surfactant-enhanced emulsification microextraction. In addition, extractions using a variety of solvents, as well as miniaturized and on-line sample preparation systems, are discussed. Applications of the different methods for the determination of carbamate pesticide residues in food and environmental matrices are included.
