In freshwater systems, microplastics and organic contaminants are prevalent pollutants. Using kinetics and isotherm analyses, this research investigates the sorption of two organic compounds (Phenol and 2,3,6-Trichlorophenol) on pristine polyethylene (PE). The hydrophilic nature of phenol is hypothesized to have low affinity for PE, on the contrary, 2,3,6-TCP is expected to have higher affinity. The goal of this study is to compare the interactions between PE and two extensively used yet physio-chemically distinct chemicals. Experimental results show 2,3,6-TCP sorption is fast (teq=24hr) with qeq 180 µg/g, while phenol sorption is slow (teq=28days), with non-detectable capacity. PE sample, having medium to high density and crystallinity seems to result in longer equilibration times and lower sorption capacity when compared to other MPs studied in the literature.

Qualitative evaluations about the disinfection capabilities of a water distribution network : a model study Nadiroğlu, Coşkun; Köken, Mete; Aydın, İsmail; Department of Civil Engineering (2014) “Chlorine” is one of the major disinfectants extensively used in distribution systems that neutralizes the disease-causing organisms. This model study evaluates the disinfection capabilities of a specific water distribution network N8.3 of Ankara water distribution system under various operating conditions. N8.3 supplies water, roughly to 40,000 people. The network is served by a pump station and pumping schedule is critical concerning the occurrence of minimum chlorine concentrations. Continuous “blind” pu...
Systematic evolution of novel 2′F-PY RNA aptamers targeting the membrane protein l-arginine/agmatine antiporter purified in mild detergent Ayoub, Nooraldeen; Son, Çağdaş Devrim; İlgü, Müslüm; Department of Biochemistry (2021-2-15) Bacterial microorganisms have developed numerous and diverse systems to handle potentially detrimental acidic conditionsintheir external environment. In particular, some pathogenic and other nonpathogenic enteric bacteriahave a number of exceptionaland well-organized acid resistance (AR) mechanismsthat work together to counter intracellular acidification and damage and enable survival under the extreme acidic conditions of the mammalian stomach. The common Escherichia coliwith both its virulent ...
The effects of aquifer heterogeneity on the natural attenuation rates of chlorinated solvents Önkal, Başak; Ünlü, Kahraman; Department of Environmental Engineering (2005) Monitored natural attenuation has been particularly used at sites where petroleum hydrocarbons and chlorinated solvents have contaminated soil and groundwater. One of the important aspects of the methodology that has been recognized recently is that the mass removal rates, the most important parameter to determine effectiveness of the methodology, is controlled by the groundwater flow regime and the aquifer heterogeneity. Considering this recognition, the primary objective of this study is to quantitatively...
A comparative study on the effects of glucose monohydrate, hot water, and sodium pyrophosphate on quality parameters and microbial flora of deboned and matured brisket Göğüş, Uğur; BOZOGLU, F.; Alpas, Hami (Wiley, 2007-09-01) Organic acids, hot water (HW), and chlorine have been commonly used incarcass decontamination for years. However, it has been observed that organic acids have adverse effects on color and are corrosive, while HW is discoloring. On the other hand, glucose fermentation by lactic acid bacteria in meat during the rigor period might be effective in microbial inhibition, without producing an adverse effect on the organoleptic quality of meat. Therefore study, briskets were treated with 6 different applications: D...
A new screening index for pesticides leachability to groundwater DEMİR, A. Ece Akay; Dilek, Filiz Bengü; Yetiş, Ülkü (Elsevier BV, 2019-02-01) Given the fact that pesticides exist in the aquatic environment at very low concentrations, it is clear that their analysis require expensive analytical techniques. Water authorities in Turkey are in need of assessing the likelihood of pesticide occurrence in groundwater in order to identify minimum number of pesticides that would be included in monitoring programs. To this purpose, the pesticides used in Turkey are ranked and those having higher leaching potentials are identified using pesticide screening ...
