چکیده انگلیسی
We examined the differences found in the concentrations of polycyclic aromatic hydrocarbons (PAHs) in sediment samples when determined by isotope dilution mass spectrometry (IDMS) using 13C-labeled PAHs (13C-PAHs) and deuterium-labeled PAHs (PAHs-d) as internal standards. The samples were analyzed by pressurized liquid extraction (PLE) in combination with gas chromatography–mass spectrometry. The observed concentrations with PAHs-d as internal standards were significantly (p < 0.05) lower (1.9–4.3%) than those determined with 13C-PAHs. The most important factor responsible for the high recovery of PAHs-d relative to 13C-PAHs and native PAHs is the higher stability of PAHs-d during the PLE process.
