In this work the qualitative and quantitative analyses of paraffins (normal hydrocarbons C 10-C 40) and polycyclic aromatic hydrocarbons (16 EPA-PAHs) were performed. The authors have analysed soil samples in order to examine the content of paraffins and the amount of PAHs. After sampling of the soil, the paraffins were extracted with acetone/n-heptane and PAHs with a mixture of acetone/cyclohexane. Clean-up of the obtained extracts were performed on Florisil in the case of paraffins and on

For the qualitative analysis of paraffins retention time window standard solution was used. In order to performe quantitative analyses external calibration method was applied. Limits of detection and determination for the PAHs found in the sample have also been determined.
