Determination of polycyclic aromatic hydrocarbons from buzzards (Buteo buteo) and tawny owl (Strix aluco) by liquid chromatography with fluorescence detection.
Supercritical fluid extraction was applied to the determination of naturally contaminated polycyclic aromatic hydrocarbons (PAHs) in bird tissue by liquid chromatography with fluorescence detection (LC-FL). Recoveries (> 90%) and relative standard deviations (< or = 7.7%) were satisfactory. The levels of 10 PAHs were analyzed in 6 classes of tissues (heart, liver, intestine, muscle, lung, and kidney) of 10 buzzards and 2 tawny owls, predatory birds from the Galicia (northwest Spain). The PAHs found most abundantly were pyrene, fluoranthene, benzo[a]anthracene, and anthracene. Chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[ghi]perylene, and indeno[1,2,3-cd]pyrene were not detected. Intestine, kidney, and lung were more polluted than other tissues.
