Source Identification of VOCs In METU Campus Through Factor Analysis
Environmental Sciences
In this study, 55 ozone precursor VOCs, which are routinely measured in PAMS (Photochemical Assessment Monitoring Station) were measured in a suburban station located at Middle East Technical University, Environmental Engineering Department in, Ankara. Daily air samples were collected in evacuated...
Investigation of Performance of Tropospheric Ozone Estimations in The Industrial Region Using Differential Artificial Neural Networks Methods
Environmental Sciences
The method of Levenberg-Marquardt learning algorithm was investigated for estimating tropospheric ozone concentration. The Levenberg-Marquardt learning algorithm has 12 input neurons (6 pollutants and 6 meteorological variables), 28 neurons in the hidden layer, and 1 output neuron for the Ozone (O3)...
Dredges' management: Comparison of regulatory frameworks, legal gaps and recommendations
Environmental Sciences
This work deals with an environmental issue affecting particularly the Mediterranean coastal countries, that of dredges handling, and investigates how it is nationally designed and regulated. The described legislative frames are based upon relevant European regulatory systems and highlight the...
The SWOT analysis for sustainable MSWM and minimization practices in Turkey
Environmental Sciences
One of the most important environmental problems is municipal solid waste management (MSWM) as a result of the rapid rise in waste generation due to industrialization, economic development, urbanization, and rapid population growth in Turkey. The collection, transportation, and disposal of solid...
Ultrasound–assisted adsorption of toxic dyes by cottonseed cake: artificial neural networks, regression models and response surface optimization
Environmental Sciences
In this study, dehydrated cottonseed cake as a low-cost and abundant byproduct in Turkey was utilized as an adsorbent for the decolorization of Reactive Blue 19 (RB19) and Reactive Yellow 145 (RY145) from aqueous solutions based on adsorption and ultrasound-assisted adsorption (UAA). Decolorization...
Treatment efficiency and sludge characteristics in conventional and suspended PVA gel beads activated sludge treating phenol containing wastewater
Environmental Sciences
Protozoa play a significant role in activated sludge systems, since they graze on dispersed bacteria, supporting a healthy food web in the activated sludge artificial ecosystem. However, operational parameters and influent properties are the most important factors affecting the composition of...
Evaluation of biomass type blue Cyanophyta algae for the sorption of Cr (III), Zn (II) and Ni (II) from aqueous solution using batch operation system: Kinetics and thermodynamic studies
Environmental Sciences
The biosorption of Cr (III), Zn (II) and Ni (II) ions from aqueous solution by dead blue algal biomass (Cyanophyta) was investigated in single metal system and batch conditions. Experimental parameters included contact time (0-140 min), pH (2-8), sorbent dose (0.1-2.0 g), initial concentrations (10...
Performance of granular activated carbon/nanoscale zero valent iron for removal of humic substances from aqueous solution based on Experimental Design and Response Surface Modeling
Environmental Sciences
Response surface methodology has been used to design experiments and to optimize the effect of independent variables responsible for higher adsorption of humic substances by activated carbon supported nanoscale zero-valent iron from aqueous solutions. The variables of initial concentration, time, pH...

Environmental Sciences
The aim of the present study is a) to examine the healthcare waste management practices in W. Greece, Peloponnese, Epirus and Ionian islands b) to investigate the implementation of the institutional frame and c) to make suggestions in order to achieve a proper Hospital Healthcare Waste Management...
Statistical evaluation and predicting the possible sources of particulate matter in a Mediterranean metropolitan city
Air Quality
In Mega-cities, such as Istanbul, urbanization causes heavy traffic. Air pollution, which originated from heavy traffic and industrialization, is one of the most important problems for the people who live in the populated cities. Due to both environmental and health effects, particulate matter...
