Alkylated Polycyclic Aromatic Hydrocarbons

Abstract Native and alkylated polycyclic aromatic hydrocarbons (PAHs) were examined in the muscle, liver, kidneys, and lungs of greater scaup (Aythya marila) and great crested grebe (Podiceps cristatus). Both species showed differences in distribution and profiles among the tissues. The highest ƩPAH concentrations were in the scaup lungs and the grebe kidneys (20 and 19 ng g−1 wet weight, respectively). Alkylated derivatives were in the range of 61 to 77% of ΣPAHs in both species. Differences in PAH profiles between birds, analyzed by PCA, were probably results of metabolic capability, not various diet. In comparison to available data from other regions of the world, PAH levels in investigated species are relatively low and do not pose a threat to birds themselves.

Concentrations of 16 polycyclic aromatic hydrocarbons (PAH) were determined in porcine and bovine kidney, liver, lung, muscle and adipose tissue samples, and in eyeballs (lens and vitreous humour) in fattener pigs and cows. The total average PAH concentrations in individual organs were: 5.4, 6.3 (kidney); 3.8, 2.7 (liver); 4.6, 5.4 (lung); 3.6, 5.1 (muscle tissue); 0.05, 0.11 (adipose tissue); 57.9, 16.3 (lens) and 14, 6.4 (vitreous humour) for pigs and cows in ng/g of wet weight, respectively. Phenanthrene, naphthalene, pyrene and fluoranthene were predominant PAH present in samples. No significant differences (P > 0.05) were found among distribution of PAH in animal bodies from several localities with various PAH exposure or between their levels in porcine and bovine organs and tissues, except for eyeballs. On the contrary, significant variations of PAH concentrations (P < 0.01) were found between species in the same tissues from the same stable. The highest total concentrations of PAH were found in porcine and bovine lenses. Analyses of porcine and/or bovine lenses for PAH content could be used for determination of animal exposure to these compounds.
