Topal, Murat; Arslan Topal, E. Işıl; Öbek, Erdal
In this study, phycoremediation of thallium toxic metal present in galery water of an abandoned mine area was investigated by using Cladophora fracta. Within the scope of the study, a reactor containing Cladophora fracta was used and it was determined whether the Cladophora fracta accumulated thallium depending on time. Additionally, the bioconcentration factor was calculated. According to research findings; the accumulations of thallium by Cladophora fracta, compared with uncontaminated alga, were 225% at 5 min, 450% at 10 min, 550% at 20 min, 575% at 40 min, 700% at 60 min, and 900% at 120 min, respectively. BCF values were between 1000-5000. This indicated that Cladophora fracta had bioaccumulation potential. As a result, this research carried out in mining area has documented the phycoremediation of thallium in gallery water of an abandoned mine area.

Topal, M.; Arslan Topal, E.I.; Öbek, E.
In the present study, the bioaccumulation of toxic/harmful pollutants (Fe, Pb, As, Cd, Cr, Ba, and Mn) by Cladophora fracta in mine gallery water was investigated. For this aim, the reactors planted with C. fracta were placed into mine gallery waters. Bioconcentration factor (BCF), metal pollution index (MPI), and accumulation capacity values were determined. According to the obtained results, the highest concentrations of Cr, Mn, Fe, Ba, Pb, Cd, and As were determined as 24.3 ± 1.2, 858 ± 27, 26,290 ± 87, 11.4 ± 0.6, 117.05 ± 5.8, 47.9 ± 1.4, and 2390.3 ± 11 mg/kg, respectively. BCF values were Fe > Pb > As > Cd > Cr > Ba > Mn. The MPI values of toxic/harmful pollutants according to days were determined as day 1 > 5 > 7 > 2 > 6 > 4 > 3, respectively. As a result, it was determined that C. fracta, which was placed in the mine gallery and exposed to the gallery waters, was effective in removing toxic/harmful pollutants. Therefore, C. fracta can be used as an alternative treatment material for the removal of toxic/harmful pollutants in mine gallery waters.

İncele - MakaleAçık Erişim2020Scopus SJRQ1Remediation of pollutants with economical importance from mining waters: Usage of Cladophora fracta
Topal, Murat; Arslan Topal, E. Is̨ıl; Öbek, Erdal
The accumulations of elements (Mo, Cu, Zn and Ni) those have both pollutant characteristics and economic importance were determined in the macroalga (green alga Cladophora fracta) exposed to mining water with the aim of presentation of the possibility of using the alga as a bioindicator of these elements. The highest element concentrations (Mo, Cu, Zn and Ni) accumulated by Cladophora fracta were determined as 2.38; 19.66; 4510.5 and 19.4 mg/kg, respectively. Bioconcentration factor values decreased in the order: Ni>Cu>Mo>Zn. The Metal Pollution Index (MPI) values calculated between 17.50 and 44.98 were used to determine the pollution degree of Cladophora fracta. As a result, it was determined that Cladophora fracta highly accumulated the elements from the mine gallery water. Therefore, Cladophora fracta was a good bioaccumulator and indicator for the remediation of the elements in mine gallery waters.
