| Abstract: | An extraction/clean-up procedure by SFE was developed for isolating PAHs from liver samples for subsequent HPLC-FL determination of ten PAHs in the enriched extract. Recoveries (90–115%) and RSD % (≤ 7.7) were satisfactory. When applied to 11 samples of bird of prey (Tyto alba) protected species and classified of special interest, from the Galicia (Northwest to Spain), benzoghi]perylene and indeno1,2,3-cd]pyrene were undetectable; chrysene and benzoa]pyrene are only detected in one sample; benzoa]anthracene and benzok]fluoranthene are only quantified in one sample and benzob]fluoranthene in two samples. The other PAHs, anthracene, fluoranthene and pyrene are present in almost all the samples. |
