摘要：

A multiresidue approach using microwave-assisted extraction and liquid chromatography with photodiode array detection was investigated for the determination of butylate, carbaryl, carbofuran, chlorpropham, ethiofencarb, linuron, metobromuron, and monolinuron in soils. The critical parameters of the developed methodology were studied. Method validation was performed by analyzing freshly and aged spiked soil samples. The recoveries and relative standard deviations reached using the optimized conditions were between 77.00.46% and 1202.9% except for ethiofencarb (46.44.4% to 1051.6%) and butylate (22.17.6% to 49.211%). Soil samples from five locations of Portugal were analysed.
