    Identifying Geogenic and Anthropogenic Aluminum Pollution on Different Spatial Distributions and Removal of Natural Waters and Soil in Çanakkale, Turkey
    (Amer Chemical Soc, 2023) Hızlı, Sezin; Koraoğlu, Aybike Gül; Gören, Ayşegül Yağmur; Kobya, Mehmet
    The Canakkale-Kirazli region (Turkey) is enriched with minerals, especially aluminum (Al), which dangerously get transported into aquatic media due to several mining and geological activities in recent years. In this study, Al and other potentially toxic metals (PTMs) including B, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Si, and Zn, in both water and soil samples, were measured for quality determination. Selected metals were also analyzed by the enrichment factor (EF), the geoaccumulation index (I-geo), the contamination factor (CF), and the pollution load index (PLI) to evaluate both water and soil pollution geogenically or anthropogenically. Also, the metals were clustered to support the pollution source with Pearson's correlation, principal component analysis (PCA), and hierarchical cluster analysis (HCA). Forty-five natural water samples and 12 soil samples were collected spatially. To perform pollution assessment, two fundamental treatment processes to remove Al pollution from the sample including the highest Al concentration (38.38 mg/L) in water were applied: (1) precipitation with pH adjustment and (2) removal with ion exchange. The pH values of water samples were changed in the range of 3-9 to test the dissolution of Al. The results demonstrated that the study area was mostly under the influence of geogenic aluminum pollution.

    Impacts of Remediation of Halogenated Organic Compounds in Soils and Sediments
    (IGI Global, 2022) Demirtepe, Hale
    Halogenated hydrophobic organic compounds (HOCs) have been used in various industrial applications and are present in many commercial products. Due to their emissions during manufacturing and discharges as wastes, halogenated HOCs such as polychlorinated biphenyls and polybrominated diphenyl ethers are ubiquitously found in the environment and create contaminated sites. To remove the contamination from these sites, various remediation techniques have been useful. The purpose of this chapter is to investigate the impacts of traditional and emerging remediation techniques on ecosystem. One of the traditional remediation techniques is dredging and the mostly studied emerging remediation techniques are bioaugmentation and biostimulation. The efficiency of these techniques is also evaluated regarding reduction in contaminant mass. Overall, this chapter presents the efficiency and possible impacts of dredging, bioaugmentation and biostimulation of soils and sediments, and the implications include the evaluation of most feasible remediation techniques by using life cycle assessment.
