Endocrine disrupting compounds, EDCs, are somewhat recently recognized pollutants which are often classed within 'emerging micropollutants' in the environment jargon. These compounds are known to interfere with the delicate balance of the endocrine system of animals and man, causing variety of undesirable outcomes. Their sources in natural waters are the domestic and industrial effluents. The main cause of concern with EDCs is their tendency to accumulate in fish causing gender shifts and reduced fecundity. Moreover, their possible interference with the water cycle and concurrent effects on the human endocrine system has been implicated. Increased usage of medication and surfactants in the household; pesticides in agriculture have all add up to the inventory of EDCs in the aqueous systems.


Removal of endocrine disrupter compounds and trace organics in membrane bioreactors
Komesli, Okan Tarik; Gökçay, Celal Ferdi; Department of Environmental Engineering (2012)
Endocrine disrupters and trace organic contaminants are recently recognized contaminants in wastewaters. Current concept is the multibarier approach where the contaminants are removed from the water cycle both by water and wastewater treatment facilities, as well as natural die-away. In this thesis work LC/MS/MS determination of selected EDC compounds, namely, diltiazem, progesterone, estrone, carbamazepine, benzyl butyl phthalate and acetaminophen, at ultra trace levels, have been carried out by optimizing...
Occurrence and Reduction of Emerging Contaminants in Sludge
Sanin, Faika Dilek (null; 2019-06-13)
Emerging contaminants consist of a wide range of anthropogenic as well as natural substances which include pharmaceuticals,personal care products, steroid hormones, industrial chemicals, pesticides and many other emerging compounds. Since theirconcentrations vary from a few ng/L to several μg/L, they may also be called as micropollutants. There has been a growingawareness and concern about these chemicals for the last few decades since many of these are known to have toxic, carcinogenic orendocrine disrupti...
Occurrence and load of micropollutants discharged from urban and industrial wastewater treatment plants to receiving environment in the Yeşilırmak Basin
İnce, İrem; Yetiş, Ülkü; Department of Environmental Engineering (2021-8-27)
The occurrence of micropollutants in the aquatic environment is an emerging topic. It is known that the wastewater treatment plants (WWTPs) are the main point sources of the micropollutants. With this regard, the purpose of the study is to determine the occurrence of micropollutants in the WWTPs, to detect the significant discharges, and to analyze the impacts of these discharges on the receiving bodies. A 2-year monitoring study was conducted in Yeşilırmak River Basin and 6 urban WWTPs (UWWTPs), 14 industr...
Seasonal monıtorıng of nonylphenol compounds ın sewage sludge
Kara Murdoch, Fadime; Sanin, Faika Dilek (null; 2015-08-27)
Nonylphenol compounds (NPnEO) enter wastewater treatment systems from a number of different sources, including domestic and industrial. These compounds start losing their ethoxy groups during treatment processes and eventually form nonylphenol diethoxylate (NP2EO), nonylphenol monoethoxylate (NP1EO) and nonylphenol (NP) as final products with higher toxic properties. Even though they are removed during wastewater treatment to a certain extent, an important fraction heavily concentrate on solids due to their...
Fate and degradation kinetics of nonylphenol compounds in aerobic batch digesters
Omeroglu, Seçil; Sanin, Faika Dilek (2014-11-01)
Nonylphenol (NP) compounds are toxic and persistent chemicals that are not fully degraded either in natural or engineered systems. Current knowledge indicates that these compounds concentrate in sewage sludge. Therefore, investigating the degradation patterns and types of metabolites formed during sludge treatment are important for land application of sewage sludge. Unfortunately, the information on the fate of nonylphenol compounds in sludge treatment is very limited. This study aims to investigate the bio...
