Hollow fiber liquid-phase microextraction of multiclass pesticides in soil samples: A green analytical approach for challenging environmental monitoring analysis

[Display omitted] •Soil samples were evaluated by the two-phase HF-LPME method in “U” shape.•HF-LPME was successfully applied for multiclass pesticides extraction in soil.•The two-phase HF-LPME method could achieve recovery values ranging from 75 to 111 %.•LOD and LOQ values were obtained in the µg/L range.•An eco-friendly method was developed using µL of organic solvent. In the last decades, pesticides have been not well administrated in agriculture causing their presence in environmental compartments, such as soil matrices. Because of that, analytical methods capable to perform the monitoring of such compounds in the environment have become crucial. Therefore, this study reports the development of a hollow fiber liquid-phase microextraction (HF-LPME) with liquid chromatography-mass spectrometry method (LC/MS) for the extraction and detection of 13 multiclass pesticides (carbendazim, diuron, metribuzin, imazapic, carboxy, epoxiconazole, thiabendazole, simazine, carbaryl, cyprodinil pyridaphenthion, quinalphos, and captan) from soil samples. The higher analytical method response was achieved with sample pH 6.0, 30.0 min of extraction time, 1000 rpm as stirring speed, and without salt addition. A linearity of R2 > 0.9800 was achieved, limits of detection, and the limits of quantification values were determined from 66.1 to 198.1 µg/L and 92.7 to 331.2 µg/L, respectively. For intra and inter days assays the values ranged from 0.1 to 10.6 % and 0.5 to 9.3 %, respectively. The method accuracy values ranged from 75.3 to 120.0 %. The developed method obtained recovery values varying from 75.2 to 111.8 %. The present study demonstrated an eco-friendlier alternative for analytical methods for soil samples which was demonstrated by AGREEprep software, showing great potential for the multiresidues evaluation in environmental samples.
