title: Determination of polycyclic aromatic hydrocarbons from buzzards (Buteo buteo) and tawny owl (Strix aluco) by liquid chromatography with fluorescence detection.
abstract: 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.
