Ten different soil samples were artificially contaminated with a mixture of four different PAH compounds (fluorene + anthracene + pyrene + chrysene) at the levels of 20 mg of each compound per kg of the soil (i.e. 80 mg kg− 1 for ∑ 4PAH) then moistured to 50% of the soil water holding capacity and incubated at the temperature 20 ± 2 ∘C. PAH content in the soils was monitored in the course of the study (180 days). The rates of PAH dissipation were evaluated on the basis of the pseudo-first order kinetic model – the results were in agreement with other literature data. Statistical evaluations indicated that losses of PAHs were related to the properties of the compounds, period of PAH/soil contact and soil characteristic. The best description of PAH dissipation was attained by multifactor linear regression models including both, soil and PAH descriptors. This permitted to explain 99–67% of results variability with the highest values corresponding to the initial periods of PAH/soil contact.
