Concentrations of 16 polycyclic aromatic hydrocarbons (PAH) were determined in porcine and bovine kidneys, liver, lungs, eyes (lens and vitreous humour), muscles and adipose tissue. Average PAH concentrations (ng/g of wet weight) in porcine and bovine organs were as follows: kidneys: 5.4 and 6.3; liver: 3.8 and 2.7; lungs: 4.6 and 5.4; muscles: 3.6 and 5.1; adipose tissue: 0.05 and 0.11; lens: 57.9 and 16.3; vitreous humour: 14 and 6.4, respectively. Phenanthrene, naphthalene, pyrene and fluoranthene were predominant PAH present in samples. No significant differences were found between the different localities with various PAH exposures. On the contrary, significant differences were found between the two species housed in the same stable. As the highest total concentrations of PAH were found in both porcine and bovine lenses, analyses of PAH concentrations in eye lenses may be used for the monitoring of animal exposure to these pollutants.
