Opis:: Organic and non-organic pollution present in the drilling waste may negatively impact flora and fauna. The tests conducted on earthworms may serve as indicators for the assessment of pollution bioavailability, i.a. heavy metals, polycyclic aromatic hydrocarbons, due to the relatively stable ratios between the concentration of certain pollutants in earthworms and soil. Moreover, earthworms are capable of metal bioaccumulation in tissues; therefore, they can be utilized as an ecological indicator of soil pollution. The studies on bioaccumulation of heavy metals from soils with the addition of drilling wastes in tissues of earthworms were conducted. The reduction percentage (R) of each scenario was calculated for the total concentration of all heavy metals. As data showed, all heavy metal content was reduced from its initial concentration.

Opis:: The paper presents the possibility of applying spent synthetic ion exchangers and sorbents based on natural zeolites for the reclamation of degraded soils. The obtained research results confirmed the improvement of the soil sorption capacity (cation exchange capacity) caused by the addition of spent ion exchange sorbents. They also enabled to determine the magnitude of changes of the analyzed parameters depending on the amount of wastes introduced to the soil. The addition of 1% (w/w) spent cation exchanger enables to increase the cation exchange capacity twice, whereas in the case of zeolite, the observed increase reaches about 20%. Simultaneously, introduction of waste ion exchange sorbents increases the content of exchangeable calcium and magnesium while doubling in the content of these macroelements is observed for 5% (w/w) and 2% (w/w) of spent ion exchanger, respectively. In the case of the exchangeable potassium content, a satisfactory increase is observed with 1% (w/w) addition of spent zeolite.

Tytuł:: Assessment of Drilling Waste Addition on the Salinity of Soils and Growth of Selected Grass Species

Opis:: The soils that sustained damage from the mining industry are threatened with high salinity. The aim of the research involved assessing the impact of drilling wastes on the salinity of soils, and the influence of salinity on the germination and growth of various grass species. The research involved the energy, germination capacity and growth of four grass species: tall fescue Festuca arundinacea (cv. Odys), red fescue Festuca rubra (cv. Areta), perennial ryegrass Lolium perenne (cv. Gazon) and smooth meadow grass Poa pratensis (cv. Alicja) in the soils with various amount of drilling wastes addition and different salinity. The drilling waste addition in the amount of 5%, 10%, 15%, 20%, 30% (v/v) (pH 4.1, EC = 8.84 µS/cm) significantly increased the salinity of the prepared mixtures to the levels of >2.5 dS/m, determined as harmful for most plants. Studies indicated that 5%, 10% and 15% (v/v) drill cuttings addition does not inhibit the growth of the considered grasses, while at the 25% addition of drill cuttings, the length of seedlings and roots is halved in comparison to the control sample without drilling waste addition. The mixture with 30% drilling waste addition, characterized by the salinity of 18 dS/m, inhibits the growth of all considered plant species. The conducted discrimination analysis indicated that cv. Gazon and cv. Odys differ from the other considered grass species, exhibiting the highest resistance to salinity caused by drilling waste addition. In turn, cv. Alicja was characterized by the lowest tolerance to salinity.
