A review of analytical methods for phenyl and sulfonylurea herbicides is reported. Extraction from environmental samples can be carried out using different techniques like liquid–liquid partition, solid-phase extraction (SPE), microwave-assisted solvent extraction, and so on. Both herbicide classes are analyzed mainly using high-performance liquid chromatography (HPLC) coupled with a mass detector. Quantification limits are around the parts per billion level for many compounds. Multiresidue determination is easy for phenylurea compounds, but for sulfonylureas is limited by the different pKa values of the compounds.
