Today, the persistent organic pollutant loads which are formed as a result of modern agriculture and industrial production are becoming very dangerous for the environment and human health. Exposure of living things to these pollutants can occur by direct exposure to pollutants emission or by transport of pollutants as a result of food chain and meteorological events. For this reason, all environmental samples should be analyzed in this context and risk assessments should be made especially for regions where pollutant emissions may occur. In this study, bottom sediment sampling was made from a total of 16 stations including 8 freshwater and 8 seawater from the region located on the coastline of Yesilirmak Basin. In sediment samples analysis were carried out for persistent organic pollutant (POP) groups (PCB, OCP) using standard methods. The toxic effects of the determined concentrations of the pollutants, which are situated in national and international legislations, primarily, were evaluated as a result of the related analysis. Gas chromatography mass spectrometry (GC-MSMS) systems were used for PCB and OCP analyses. As a result of the analyses, for 7 total PCB congeners with 23.73 mu g kg(-1) near the smelting and electrolysis plant at the Marine-5 coded marine station and for the OCP compounds, the highest concentrations were detected as agricultural activities at 8 freshwater sampling stations. PCB 138 compound with 4.99 PCB mu g kg(-1) for PCB and in the freshwater sampling stations 10.03 mu g kg(-1) for OCP with 4,4'-DDT have been observed. When the total results of POP analysis of sediment samples are evaluated, it has been observed that there are unintentionally occurring compounds, but their effect levels are low in terms of aquatic life.

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...
Investigation of the properties of portland slag cement produced by separate grinding and intergrinding methods Geven, Çağlar; Hoşten, Çetin; Department of Cement Engineering (2009) In recent years, there has been a growing trend for the use of industrial by-products in the production of blended cements because of economical, environmental, ecological and diversified product quality reasons. Granulated blast furnace slag, a by-product of the transformation of iron ore into pig-iron in a blast furnace, is one of these materials which is used as a cementitious ingredient. The aim of this study is to investigate the properties of Portland slag cement (CEMII/B-S) by using separate grinding...
Investigation of processing parameters on production of hemicellulose based films from different agricultural residues via extrusion Akınalan, Büşra; Bölükbaşı, Ufuk; Özkan, Necati; Department of Chemical Engineering (2014) Today, due to the environmental concerns about petroleum based polymers, the use of renewable polymers including polysaccharides in food packaging applications is increasing rapidly. In the present study, hemicellulose was extracted from corn cobs, wheat straw and sunflower stalks, and two different techniques, solvent casting and extrusion, were utilized for biodegradable film production. Films produced from different types of biomasses were compared in terms of their mechanical, thermal and morphological ...
Evaluation of the Properties of Corn Cob Hemicellulose Based Biodegradable Films Obtained by Extrusion and Solvent Casting Methods Akınalan Balık, Büşra; Özkan, Necati; Bölükbaşı, Ufuk (2019-05-28) The remarkable consumption and environmental concerns related to the utilization of fossil based resources have led researchers to focus on renewable raw materials. Lignocellulosic biomass, the fibrous part of plants with a complex matrix comprising different polysaccharides, mainly cellulose, hemicellulose and lignin, is the most abundant, inexpensive, non-starch renewable source in the world. In the present study, hemicellulose, which was obtained from corn cobs by alkali extraction method (...
Investigation of alkaline pretreatment parameters on amulti-product basis for the co-production of glucose and hemicellulose based films from corn cobs Toraman, Hilal Ezgi; Bakır Bölükbaşı, Ufuk; Özkan, Necati; Department of Chemical Engineering (2012) There is an increasing trend in the world for using renewable sources of fuels and chemicals due to the continuous depletion of fossil fuel reserves besides the environmental issues related with the exploitation of these resources. Lignocellulosic biomass is seen as the most promising candidate to be used instead of fossil sources because of its availability, relatively low price and less competition with food and feed crops. In this study, corn cobs, a lignocellulosic agricultural waste, were subjected to ...
