Abstract

Selected polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) were detected by gas-chromatography coupled to triple quadrupole mass spectrometry (GC-QqQ-MS/MS) in marine sediments collected in central Italy. Total PCDD/Fs concentrations ranged from 11.58 to 193.29 pg/g d.w., with PCDFs as the major contributors in most cases. The congener profiles were characterized by high OCDD (70.7 %-91.4 %). The PCDD/Fs values are within or close to the Environmental Canada sediment reference values (0.85 pg TEQ/g d.w.). GC-QqQ-MS/MS can be a suitable alternative to standard methods for PCDD/Fs determination in environmental samples. The measured PCDD/Fs amounts could be considered as a basis for future monitoring programs. © 2013 Springer Science+Business Media New York.
