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.

İncele - MakaleAçık Erişim2020Scopus SJRQ2Performance of Cladophora fracta for Bioaccumulation of Critical Raw Materials from Mine Gallery Waters

We investigated the accumulation of critical raw materials (CRMs) in macroalga (green alga Cladophora fracta) in mine gallery water with the aim of presentation of the possibility of using the algae as a bioaccumulator of CRMs. The CRMs investigated in the present study were lanthanum (La), vanadium (V), tungsten (W), scandium (Sc), bismuth (Bi), antimony (Sb), gallium (Ga) and cobalt (Co). The highest concentrations of La, V, W, Sc, Bi, Sb, Ga and Co were determined as 3.16 ± 0.15, 22 ± 1.0, 2.0 ± 0.1, 2.4 ± 0.12, 0.21 ± 0.01, 2.47 ± 0.13, 1.4 ± 0.07 and 7.28 ± 0.35 mg/kg, respectively. Bioconcentration factor values followed the order of La > V>W > Ga > Sb > Bi > Co > Sc. Also, metal pollution index (MPI) is used in order to identify the degree of pollution of C. fracta. The MPI values calculated were between 1.09 and 2.2. As a result, it was determined that C. fracta highly accumulated the CRMs from the mine gallery water and was a good bioaccumulator in remediation technology. In this way, it is possible to minimize or eliminate the environmental risks of the materials in the gallery waters.

Topal, Murat; Arslan Topal, E. Işıl; Öbek, Erdal
In this study, potential health risks in terms of arsenic in grapevine exposed to gallery waters of an abandoned mining area in Turkey were investigated. The concentrations of arsenic were determined in roots, stems, and leaves. The translocation factors and bioconcentration factors were calculated. The highest arsenic concentration in the grapevine was determined as 539.4±27 mg/kg, for root. The arsenic concentrations in grapevine as follows: Root>Leaf>Stem. The estimated daily exposure followed an order for the male, female, and children: dermal<inhalation<ingestion<dietary. The non-carcinogenic and total hazard index values calculated for As were higher than 1. The risk of arsenic to be carcinogenic has been determined. The highest carcinogenic risk can be listed as dietary > ingestion > inhalation > dermal. In our study, calculated carcinogenic risk values in terms of dietary, inhalation, and ingestion are higher than 10−4-10−6. As a result, the highest cancer risk on human health was determined as a dietary intake of grapevine leaves according to the calculated carcinogenic risk values.

In this study, the efficiency of Lemna gibba L. on tetracycline (TC) removal from the solutions prepared at various initial TC concentrations (50, 100 and 300 µg/L) was investigated. The study was conducted in the reactors planted with Lemna gibba L. plants. Lemna gibba L. plants in the reactors were harvested at various hydraulic retention times. Then, the concentrations of TC were determined by using LC/-MS-MS. The maximum removal efficiencies for the TC50, TC100 and TC300 in the planted reactors were 99.8 ± 4.1; 99.9 ± 4.9 and 99 ± 4.9%, respectively. The harvesting times for Lemna gibba L. at TC50, TC100 and TC300 concentrations were determined to be 12, 8 and 12 hours, respectively. First-, second- and pseudo-first-order kinetics are determined in the planted reactors (with Lemna gibba L.). According to the study results, second-order kinetics were obtained at TC50, TC100, TC300 concentrations. As a result, the Lemna gibba L. plant can be used as an alternative treatment method to other advanced treatment methods and it can be done with a cheap method by adapting to existing treatment plants. Lemna gibba L. plants can be used to remove pollutants by applying them to polluted lakes and water bodies.
