Temporal and Spatial Distributions of Bisphenol A in Marine and Freshwaters in Turkey

2019-02-01
Bisphenol A (BPA), a chemical component used in the manufacture of plastics, is commonly introduced to and detected in aquatic environments. This is the first study conducted to understand the distribution of BPA in the marine and freshwaters of Turkey. The purpose of this study is to report BPA concentrations measured from a time-series conducted in coastal waters of Erdemli and regional rivers located in the northeastern Mediterranean region. Furthermore, seawater samples obtained from other Turkish coastal areasThe Black Sea, Bosphorus, Sea of Marmara, and the Mediterranean Seaalso were investigated to gain a better understanding of regional and seasonal variations of BPA concentrations in Turkish Seas. Whilst spatial variation in BPA concentrations was very low, temporal variation was found to be high. It has been shown that BPA can reach the deep sea environment (>500m depth). This study indicated that BPA contamination has reached serious levels at another location in the world.

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...

Boric acid and sodium borates are classified as toxic to reproduction in the CLP Regulation under "Category 1B" with the hazard statement of "H360FD". This classification is based on the reprotoxic effects of boric acid and sodium borates in animal experiments at high doses. However, boron mediated reprotoxic effects have not been proven in epidemiological studies so far. The epidemiological study performed in Bandirma boric acid production plant is the most comprehensive published study in this field with ...
Micellar enhanced ultrafiltration with nonionic surfactants (MEUF)
Çağlar, Toprak; Çulfaz Emecen, Pınar Zeynep; Yılmaz, Levent; Department of Chemical Engineering (2021-9)
Butanol is a versatile chemical used in many different fields such as electronics, cosmetics, and textiles, and the synthesis of many other chemicals. In fermentative butanol production, in addition to butanol; acetone and ethanol are released in the aqueous environment, too. To separate butanol from this mixture, which is called the ABE mixture, different methods are available. The project's main purpose is to develop an alternative method to these separation techniques by using Micellar Enhanced Ult...
Degradation of Bisphenol A in Natural and Artificial Marine and Freshwaters in Turkey
Kocaman, Emel; Özhan, Koray (2019-09-01)
Bisphenol A (BPA), one of the important synthetic chemicals, has been produced at high volumes since the 1960s. These chemicals are commonly detected in the marine and freshwater environments; however, their transformation in aquatic environments depends on many parameters. This study aims to investigate the degradation of BPA in marine and freshwaters under different conditions in terms of microbial degradation, photodegradation, and temperature effect. The results showed that BPA content in samples prepar...
Source Apportionment of Personal Exposure to Fine Particulate Matter and Volatile Organic Compounds using Positive Matrix Factorization
PEKEY, HAKAN; PEKEY, BEYHAN; ARSLANBAŞ, DEMET; BOZKURT, ZEHRA; DOĞAN, GÜRAY; Tuncel, Süleyman Gürdal (2013-01-01)
The objective of this study was to identify potential sources of personal exposure to fine particulate matter (PM2.5), volatile organic compounds (VOCs), NO2, SO2, and O-3 in an urban and industrial area of Turkey between May 2006 and January 2007. Personal exposures were determined once per person in 28 adults over a 24-h period. Energy dispersive Xray fluorescence and a wavelength dispersive X-ray fluorescence spectrometry were used to measure 15 elements in PM2.5, including Al, As, Ca, Cr, Cu, Fe, K, Mn,...
