Four-way modeling of 4.2Â K time-resolved excitation emission fluorescence data for the quantitation of polycyclic aromatic hydrocarbons in soil samples

► Fifteen EPA-PAHs are determined in soil without chromatographic separation. ► Quantitation is based on 4.2 K fluorescence time-resolved excitation-emission cubes. ► Data is processed with multivariate calibration methods (PARAFAC and U-PLS/RTL). ► PAHs are determined at the ng g−1 to pg g−1 level with only 0.05 g of soil. ► The 250 μL of organic solvent per sample makes the method environmentally friendly.
