With respect to their adverse health and environmental effects, halogenated organic compounds (HOCs) are among the most important priority pollutants. HOCs cannot be easily biodegraded. However. if suitable microbial cultures are acclimated to these compounds properly, and the optimum operating conditions are achieved, HOCs can be removed with biological methods. Recently, great interest has focused on reductive anaerobic dehalogenation for the removal of these compounds. This process yields lower halogenated compounds which are less toxic and more amenable to further biodegradation. Chloroacetic (CAA), trichloroacetic (TCAA), and 2,4-dichlorophenoxyacetic acids (2,4-D) are significant industrial compounds mainly used in herbicide, pesticide, and dye manufacturing. The objective of this study was to: (i) investigate the inhibitory effects of CAA, TCAA, and 2,4-D; and (ii) determine the optimum loading strategy of these HOCs to anaerobic cultures. To this purpose Anaerobic Toxicity Assay (ATA) and Optimum Loading Strategy experiments were conducted for CAA, TCAA, and 2,4-D, The results of this study are expected to develop an optimum loading strategy of HOCs to anaerobic systems and contribute to more effective use of anaerobic reductive dehalogenation of HOCs.

Evaluation of Performance of Arsenic Bioreporter Immobilized Electrospun Membranes for Arsenic Detection in Water
Arık Kınalı, Nehir; Öktem, Hüseyin Avni; Tezcaner, Ayşen; Department of Molecular Biology and Genetics (2022-12-9)
Heavy metal pollution, which is growing and threatening the health of all living things as well as human health, can lead to serious lifelong consequences. It is very important to detect and monitor these heavy metals that cause environmental pollution. In addition to traditional laboratory techniques, the use of bacterial biosensors to detect heavy metals has come into focus. In addition, it is known that the immobilization of these bacterial biosensors is more advantageous in many respects, such as being ...
Investigation of influent COD/TAN ratio and loading rate effects on carbon and nitrogen removal via aerobic granules
Kocatürk, İrem; Bayramoğlu, Tuba Hande; Department of Environmental Engineering (2014)
Aerobic granulation serves as a promising treatment technology over the conventional systems due to its advantages such as high biomass retention capacity, high settleability, ease of separation from the effluent, toxicity resistance, capacity to handle high organic loading rates and suitability for high chemical oxygen demand (COD) wastewaters. The scope of the thesis is to investigate the influent COD/total ammonifiable nitrogen (TAN = NH4-N + NH3-N) ratio and loading rate effects for the removal of carbo...
Investigating the uptake and acquisition of potentially toxic elements in plants and health risks associated with the addition of fresh biowaste amendments to industrially contaminated soil
Yousaf, Balal; Liu, Guijian; Abbas, Qumber; Wang, Ruwei; Imtiaz, Muhammad; Zia-ur-Rehman, Muhammad (2017-11-01)
Soil contamination by potentially toxic elements (PTEs), due to rapid industrialization and urbanization, is a serious environmental concern that has been threatening both the sustainability of various agroecosystems and human health. Efforts to investigate the bioavailability, transfer, and accumulation of PTEs in the soil-plant system and their possible health consequences have almost exclusively focused in the past studies. However, there is limited evidence for increased human exposure to PTEs through d...
Prediction of fate of selected priority pollutants considering their transformation products using in-silico methods
Barlas, Nezahat Gülücük; İmamoğlu, İpek; Department of Environmental Engineering (2020)
As the number of chemicals used in commerce is continuously increasing, the task of evaluating the fate of chemicals along with their impacts on the environment becomes challenging. In this study, fourteen priority pollutants, namely, aclonifen, alachlor, atrazine, BDE-153, bifenox, chlorfenvinphos, chlorpyrifos, DEHP, dicofol, diuron, hexachlorobutadiene, pentachlorobenzene, trichloromethane, and trifluralin as well as p,p’-DDT as an impurity of dicofol, were selected among the 45 priority pollutants regul...
Performance of ozone and peroxone on the removal of endocrine disrupting chemicals (EDCs) coupled with cost analysis
Ölmez Hancı, Tuğba; Dogruel, S.; Emek, A. D. Allar; Yilmazer, C. Eropak; Cinar, S.; Kiraz, O.; Citil, E.; Orhon, A. Koc; Siltu, E.; Gucver, S. M.; Ozgun, O. Karahan; Tanık, Ayşe Gül; Yetiş, Ülkü (IWA Publishing, 2020-08-01)
Micropollutants such as endocrine disruptors are one of the most important groups of chemicals polluting water resources. Conventional treatment systems may not be effective for the removal of endocrine disrupting chemicals (EDCs), and the fate of these chemicals should be carefully monitored in the effluent of wastewater treatment plants (WWTPs). Additional treatment methods such as advanced oxidation processes can be used for the removal of endocrine disruptors. This study presents the existence of endocr...
