    Soil contamination by petroleum substances in the vicinity of oil production wells
    (2016) Wartak, Joanna; Chruszcz-Lipska, Katarzyna; Knapik, Ewa; Rychlicki, Stanisław
    The paper presents the study of various indicators of soil contamination by petroleum substances from the area of active exploitation of oil deposits in the south of Poland. Nineteen studied soil samples were taken directly around the production wells (0–1 m) or their vicinity (1–7 m) at a depth of 0.1 to 0.3 m. Collected samples were tested for the presence of benzene, toluene and xylene (BTX), and polycyclic aromatic hydrocarbons (PAHs) such as phenanthrene, anthracene, fluoranthene, fluorene, pyrene, benzo(a)anthracene, chrysene, benzo(a)pyrene, dibenz(a,h)anthracene and benzo(g,h,i)perylene. An analysis of the content of these chemical compounds in the soil samples was performed by gas chromatography. The observed results were interpreted to determine the hazard for the natural environment and human health. The evaluation of soil samples was based on the new Regulation of the Ministry of Environment of 1 September 2016 regarding the assessment of contamination of the surface of the earth (Journal of Laws 2016 Nr 0, item 1395) as well as guidelines presented by the Institute of Soil Science and Plant Cultivation (ISSPC).

    A synthetic zeolite produced from fly ash after combustion of coal was modified with the cationic surfactant – HDTMA-Br – in single and double amount of external cation exchange capacity (ECEC). The aim of the study was to determine the sorption efficiency of the surfactant-modified zeolites and the synthetic zeolite in terms of BTX. The dynamic sorption experiments provided the information on the maximal sorption efficiency of zeolites in terms of BTX. The water solutions of BTX were used in experiments of the static sorption. It was meant to deliver data on capability of the organo-zeolites and the raw zeolite to sorb BTX in the actual conditions. The results of both series of experiments showed that modifications of zeolite with HDTMA significantly enhances zeolite’s potential to sorb BTX. Additionally, an attempt was made to define whether the FTIR method could be useful in the quantitative determination of BTX sorbed on the zeolite.
