  abstract = {{P}olycyclic aromatic hydrocarbons ({PAH}s) and pesticides are among the most widespread organic contaminants in aquatic environments. {B}ecause of their aromatic structure, {PAH}s and pesticides have intrinsic fluorescence properties in the ultraviolet/blue spectral range. {I}n this study, excitation–emission matrix ({EEM}) fluorescence spectroscopy and parallel factor ({PARAFAC}) analysis were used to characterise and discriminate fluorescence signatures of nine {PAH}s and three pesticides at the µg {L}-1 level in the presence of humic substances (0.1-10 mg {C} {L}-1). {T}hese contaminants displayed a diversity of fluorescence signatures regarding spectral position (λ{E}x: 220-335 nm, λ{E}m: 310-414 nm), {S}tokes shift (39-169 nm) and number of peaks (1-8), with detection limits ranging from 0.02 to 1.29 µg {L}-1. {T}he {EEM}/{PARAFAC} method applied to mixtures of {PAH}s with humic substances validated a seven-component model that included one humic-like fluorophore and six {PAH}-like fluorophores. {T}he {EEM}/{PARAFAC} method applied to mixtures of pesticides with humic substances validated a six-component model that included one humic-like fluorophore and three pesticide-like fluorophores. {T}he {EEM}/{PARAFAC} method adequately quantified most of the contaminants for humic substance concentrations not exceeding 2.5 mg {C} {L}-1. {T}he application of this method to natural (marine) samples was demonstrated through (1) the match between the {E}x and {E}m spectra of {PARAFAC} components and the {E}x and {E}m spectra of standard {PAH}s, and (2) the good linear correlations between the fluorescence intensities of {PARAFAC} components and the {PAH} concentrations determined by {GC}-{MS}.},
