Supercritical Fluid Extraction of Polycyclic Aromatic Hydrocarbons from Seaweed Samples Before and After the Prestige Oil Spill

Samples of seaweed which are used for human consumption were collected along the Galician coast (NW Spain), in order to determine the level of contamination from polycyclic aromatic hydrocarbons, by supercritical fluid extraction and liquid chromatographic analysis. No detection was made of benzo[a]...

Description
Summary:Samples of seaweed which are used for human consumption were collected along the Galician coast (NW Spain), in order to determine the level of contamination from polycyclic aromatic hydrocarbons, by supercritical fluid extraction and liquid chromatographic analysis. No detection was made of benzo[a]pyrene, benzo[a]anthracene, benzo[b]fluoranthene, benzo[ghi]perylene and dibenzo[ah]anthracene. PAHs were found and quantified in only two samples. The PAHs found were the following: anthracene, chrysene, fluoranthene, fluorene and pyrene. The levels found were below maximum limits established by the Spanish Food Safety authority (
