Occurrence of aliphatic and polyaromatic hydrocarbons (PAHs) in Mytillus galloprovincialis from the traditional market in Marseille, France, by Gas Chromatography triplequadropole tandem Mass Spectrometry (GC-QQQ/MS)

摘要

Mediterranean mussel, Mytillusgalloprovincialis collected from the traditional market in Marseille, France,have been analysed using GC-QQQ/MS for their hydrocarbons (n-alkanes and polyaromatic hydrocarbons (PAHs)) extentwith two different solvent extraction, such as heptane:dichloromethane (HEP:DCM;1:1) and heptane:acetone (HEP:ACE; 1:1). The results showed hydrocarbons yielded from heptane:acetone extractionwere 28335 μg.kg~(-1) mussels dw (Σ n-alkanes C_(15-34)) and 202 μg.kg~(-1) mussels dw(ΣPAHs) while the yield from heptane:DCM extract was lower ca. 27026 μg.kg~(-1)musselsdw and 133 μg.kg~(-1) mussels dw respectively from the Σn-alkanesC_(15-34) and ΣPAHs.High hydrocarbon levels can be affected by the presence of lipids or other metabolites in mussels that have the same polarity with hydrocarbon compounds which has interferred the measurement. Several ratio parameter of n-alcanes and PAHs source in the mussels were evaluated to asses the origins of their hydrocarbons in mussels from which we suggested origins of hydrocarbons were pyrolytic and biogenic rather than petrogenic.
