摘要：Highlights•These results allowed to broaden the range of soils that can be analyzed with the proposed methodology.•In the worst case (loamy sand soil), the original methodology allowed the analysis of 180 compounds with adequate recoveries.•For analytes outside the acceptable range in this soil and the other soil type analyzed, correction factors are proposed.AbstractSoil is one of the environmental compartments most affected by pollution. From this medium, the organic compounds can be emitted to the groundwater, the atmosphere, or the biota. Thus, having adequate methods of analysis of organic pollutants in this matrix is essential. However, the soil is a very complex matrix whose organic and inorganic components can determine the degree to which they are retained. Therefore, the methods must account for the various soil characteristics. In this study, the performance of an extraction method that had been already validated in clay loam soils for more than 300 organic compounds of very different nature including pesticides, PhACs, ARs, and POPs has been evaluated in four additional representative soil types of the agricultural land of the Canary archipelago: sandy loam, sandy clay, clay and loamy sand. For this purpose, recovery experiments have been performed at a single concentration (50 ng g−1) in each soil type. When there is a significant difference according to the criteria applied for a given compound, a factor has been calculated to correct the difference in performance in each soil type.•These results allowed to broaden the range of soils that can be analyzed with the proposed methodology.•In the worst case, which is the loamy sand soil, the original methodology allows the analysis of 180 organic contaminants with adequate recoveries. For analytes outside the acceptable range in this soil and the other soil type analyzed, correction factors are proposed.Graphical abstractDisplay Omitted
