Catalysis has manifested its role as a fundamental tool in pollution prevention. While catalysis has long been utilized in increasing efficiency, yield, and selectivity, it is now also recognized as accomplishing a wide range of green chemistry goals. Air pollutants produced by industrial and man-made emissions possesses a unique property that it could affect regional and global receptors. Measuring and defining the levels of pollutants and its sources whether it is local, regional or global should precede the precautions and measures that should be taken to reduce the levels of a particular pollutant. In this article the air quality at the Black Sea region of Turkey is being discussed. Moreover, it endeavors to locate the possible sources of the different pollutants at local, regional and long range transported scales. About 196 rainwater samples were collected over the Black Sea region of Amasra between 1995-1999 and analyzed for major and trace ions. Although statistical tools do provide information on the type of sources and processes affecting the site, they do not provide information on where these sources are located. A back trajectory has to be included in the evaluation to incorporate geographical information in analytical results. To compute the PSCF for each ion the back trajectories were computed using ECMWF model, which is an isentropic 3-D model. Then number of 1 hour-long segment of the 3.5 daylong trajectories in each defined sub-region is determined. This study shows that, the Black Sea region receives different amounts and types of anthropogenic pollutants via long-range transport according to trajectory models. The highest PSCF values for H+ are calculated for central Europe and Russia have fairly high contribution to observed free acidity in our samples. The main source areas for SO4 2- were found to be central Europe and Northwestern Turkey (Marmara region or Istanbul–Kocaeli industrial area).

Ambient VOC concentrations in the city of Balikesir and its environment
Yalçın, Giyasettin Efdal; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2013)
The assessment of volatile organic compounds (VOCs) has become an important field of interest in atmospheric pollution. This study quantifies and characterizes the ambient levels and spatial distribution of VOCs in urban and rural areas of Balıkesir. In addition, for the city drinking water dam excess flux from the traffic estimation was done. For these assessments passive sampling of VOCs performed at approximately 50 locations in and around the city of Balıkesir and analyzed with GC-FID system. Tenax TA w...
Comparison of optical measurements for better NI tracking in bacteria
Sungur, Sıla; Gözen, Ayşe Gül; Department of Biology (2015)
Metal pollution is a common problem in industrial areas. Microorganisms, as well as macroorganisms are affected from metal pollution. In order to cope with this problem, microorganisms develop resistance mechanisms. Traditional microbiological techniques alone are not sufficient in resistance studies. Additional data acquisition by using other measurement techniques and devices are also required. However, there are differences in sentitivities of the measurement devices. A given device may work under a set ...
Environmental Applications of Natural Zeolites
Kazemian, Hossein; Gedik, Kadir; İmamoğlu, İpek (2012-01-01)
Environmental pollution particularly at very low concentrations is very difficult to remove from contaminated media. Adsorption by means of relatively inexpensive natural adsorbents such as zeolites can be considered as a cost effective alternative treatment of such contaminated streams. The unique chemical and structural characteristics of natural zeolites made them potential materials for a multitude of environmental applications where materials are needed for effective binding, adsorbing, and filtering. ...
Inorganic Cadmium Detection Using a Fluorescent Whole-Cell Bacterial Bioreporter
Elcin, Evrim; Öktem, Hüseyin Avni (Informa UK Limited, 2020-11-01)
Cadmium pollution has become a serious environmental issue due to its toxicity and frequent entrance into environment components such as soil, water, and air via many anthropogenic sources. Over the last two decades, whole-cell bacterial bioreporters have been acknowledged as bio-sentinels for the determination of toxic heavy metals. Herein a sensitive and quite specific bacterial bioreporter was developed to cope with the need for the rapid and simple determination of cadmium. The construction and characte...
Sustainability considerations on effective use of resources for small household appliances
Oğur, Dilruba; Doğan, Çağla; Department of Industrial Design (2014)
The use phase of many products’ lifecycle has significant impacts on the environment that are largely determined by the use behaviour. Yet, those impacts mostly remain unnoticed, since individuals are unaware of the potential environmental consequences of their everyday practices and interactions with products, and have insufficient means to find them out. This study explores and examines use patterns and behaviours throughout the use phase of the small household appliances, particularly electric tea makers...
