Derivative synchronous fluorescence spectrometry with double scans method was established to simultaneously determine the dissolved 1-methylphenanthrene (1-MP) and its metabolites such as 1-hydroxy-2-naphthoic acid (1H2NA) and salicylic acid (SA). With this method, the linear ranges for determination of 1-MP, 1H2NA and SA were 0.02-1.30 μmol/L, 0.02-7.60 μmol/L and 0.01-5.20 μmol/L, the detection limits (LODs) of 1-MP, 1H2NA and SA were 0.11, 0.33 and 2.90 nmol/L, the relative standard deviations (RSD) were less than 2%, and the recoveries were 97.4%-108.6%. This method was suitable for the simultaneous determination of 1-MP, 1H2NA and SA in the dissolved 1-MP microbial degradation process under the laboratory simulation condition, showing practical application potential in investigation of 1-MP degradation process and mechanism in situ.
