| Description
| - Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants contaminating all components of the environment. The soil is polluted by these substances mainly due to dry and wet deposition from the atmosphere and fields irrigation with wastewater from oil or coal processing industries. Earthworms, common soil organisms, were used to evaluate the load of this environmental component by PAHs. The influence of PAHs on earthworm Eisenia fetida was evaluated according to the OECD methods No. 207 (,,Earthworm Acute Toxicity Tests%22, 4 April 1984). A standard mixture containing 16 individual PAHs was used in the test. PAHs were administered into defined substrates in concentrations of 20, 40 and 60 each individual PAH in dry substrate. The relation between soil contamination and soil organisms, i.e. the bioavailability of PAHs, was evaluated on the basis of determining their content in tissues of earthworms and in the substrate. Samples of the substrate and tissues were homogenized, dehydrated using anhydrous sodium sulphate and than were extracted by dichloromethane. PAHs were then determined following cleaning the extract by column chromatography using gas chromatography-mass spectrometry. There was no acute toxicity during the 14-day test with PAHs. Our analyses document the fact that PAHs show a higher affinity to animal tissues than soils. The relation between soil contamination and soil organisms, i.e. the bioavailability of PAHs, was evaluated on the basis of determining their content in tissues of earthworms and in the substrate. For 16 PAHs the bioaccumulation factor ranged from 0.25 to 5.69 values.
