Soil pollution was simulated by means of artificial heavy metal enrichment, in the presence of treated wastewater, and its effect on the growth characteristics of Beta vulgaris L. (red beets) i.e. on the dry matter yield, and on beet quality expressed in terms of dry matter heavy metal, nitrogen and...

The Amvrakikos Bay is one of the most important ecosystems in the Mediterranean with great environmental, ecological and biological value. However, over the years, water quality has suffered severe degradation and is now one of the most polluted environmental areas in Greece. In the present study...

Particles with aerodynamic diameters 1 μm (PM1) damage human health more severely than do coarse particles. In this study, PM1 number concentration, traffic flow, temperature and relative humidity in both a residential underground garage and at the entrance/exit, wind velocity at the entrance/exit...

It is an indisputable fact that any environmental clean-up technology generating certain kind of effective result would be easily supported. One of them includes Permeable reactive bio-barrier which is an innovative technology started from 90’s to treat a variety of contaminants along the natural...

Wind energy is a resource that does not require any fuel or feedstock to be treated, refined or transported. It does not produce air pollution and hazardous waste. Because of these, wind energy, one of the major renewable energy sources, has been widely used in recent years. In this work, a three...

In this study, we investigated the effects of Genetically Modified (GM) Maize on liver and kidney tissue weights, malondialdehyde (MDA) and glutathione (GSH) levels of liver and kidney tissues in New Zealand Rabbits. For this purpose, rabbits were divided into three groups: parental, first...

Three-dimensional numerical simulations, performed using the MIKE 3 FM (HD) code, have been used to study the effect of a severe wind event on the early stratification structure in the Gulf of Patras, Greece. Before the onset of the severe wind event thermocline was at an approximately mean depth of...

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)...

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...

Sulfur dioxide (SO2) emissions lead to negative environmental impacts and it is considered as an indicator for the larger group of gaseous sulfur oxides (SOx) in the air. In this paper, the dimethylamine (DMA) solution was used as the absorbent in a α-Al2O3 hollow fiber membrane contactor that is...

There is increasing concern about indoor air pollution worldwide due to its adverse health effects. One of the predominant indoor air pollutant groups is assumed to be volatile organic compounds (VOCs), including a variety of hydrocarbons with different functional groups. Among VOCs, some species...

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...

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...

A wide range of technologies has been developed for the removal of dyes from wastewaters to decrease their environmental impact. Wastewater containing dyes is generally treated using more than one process such as adsorption/biosorption. In this study, effects of initial pH (2-8), initial azo dye...

The discharge of colored textile wastewaters containing dyes with different chemical characteristics into the receiving streams is a problem for toxicological, ecological and also esthetical reasons. Most of dyes are stable, and not easily degradable by the conventional treatment methods, so removal...
