AbstractEcological economics is an emerging field that offers significant room for creativity and innovation at the conceptual level on how to operationalize sustainability. It integrates economics with ecology and many elements from both the natural and social sciences to provide an integrated perspective on environment-economy interactions. A major policy dilemma that ecological economics addresses is how policy-makers can influence markets, so that they receive the 'right' signals from the na...

Actual trends in papermaking concern on the use of recycled fibers and minimizing effluent volume by closing water circuit. Beside environmental and economic advantages, both trends can lead to serious problems in papermaking processes due to contaminants introduced with recycled fibers and their accumulation in closed water system. A key factor to avoid disturbances in the papermaking is to prevent the accumulation of detrimental compounds. In this respect, first it is necessary to find out met...

AbstractMunicipal solid waste (MSW) management is an important and challenging issue for sustainable development. It is also one of themost controversial problems and a subject of an ongoing debate between different interested parties. A particularly controversial issue is MSW incineration (with or without energy recovery) which has in many countries become a socially unacceptable option for dealing with solid waste. On the other hand, the increasing amounts of waste each year demand immediate a...

Field-collected retort water was augmented with organics to obtain a range of initialCOD:SO42- ratios (0.5:1 to 2:1), and treated in two different MFC designs (tubular and two-chambered). The two-chamberedMFCs exhibited COD and sulfate removal 1 to 2 orders of magnitude higher than those of the tubular MFCs. The tubular ...

The performance of the biological combined system was monitored over a 75-day period. The results revealed tha...

AbstractLithuania is planning to construct a new nuclear power plant nearby the closed one. The possible radioactive pollution can be one of the main problems in its surroundings. Results of investigations of the gamma radiation equivalent dose rate (EDR) at new nuclear power plant sites are presented. Main factors influencing the level of the EDR are identified and evaluated, and geological structure of alternative sites is discussed. The gamma spectrometry data showed that the dominant influen...

AbstractOil spills inflict serious pollution on the environment. Numerous environmental rules and regulations have been made to improve oil spill response and cleanup performance. However, current oil spill control technologies have failed to ensure environmental safety and ecosystem integrity. Cleanup efforts often lead to more environmental hazards in one way or the other causing public outcry for alternate energy sources. Since hydrocarbon driven energy demand is expected to rise in the fores...

AbstractOceans have been proved to be an important resource due to their abundant reserves in oil and gas. However, because of the extent of oil exploration and development in recent years, the marine ecological environment has been increasingly affected. At present, the control and treatment of environmental pollution from offshore drilling both at home and abroad have focused on end-treatment after problems have already emerged. Nevertheless, preventative measures and appropriate control links...

AbstractThe aim of the present study was to investigate the mechanism of Cr(VI) bioaccumulation by livingand active Phanerochaete chrysosporium. Fungal growth was inhibited beyond 10 mg L-1 Cr(VI) concentration thereby reducing the chromium bioaccumulation capacity. The optimum pH was found to be 6 for the growth and bioaccumulation of Cr(VI) by P. chrysosporium. Bioaccumulation efficiency decreased from 81.47% to 23.82% when Cr(VI) concentration was increased from 10 to 40 mg L-1. A Fourier tra...

The respective influences of some key process parameters were studied, such as mixing conditions, initial pH, and current on aluminium electrodes. Experimental results showed that a CBZ removal efficiency of 62% was observed under...

Abstract The use of hydrogen in spark ignition engines as a supplementary fuel can enhance combustion and reduce toxic emissions. Difficulties in hydrogen storage and production limit its use in internal combustion engines. This paper investigates the performance of a spark ignition engine with the addition of a mixture of hydrogen (H2) and oxygen (O2) into the intake manifold. Hydrogen is produced by an alkaline electrolyser and consumed simultaneously to eliminate the need for a storage de...

Abstract The Southeastern Black Sea coastal region in Turkey and Georgia is under threat of severe coastal erosion and shoreline recession. The main reason for this problem is the response of the coast to human activities. While water discharge rates were reduced by dams by approximately 7% only, about 98% of the suspended sediment is being captured by the dams, leading to reservoir siltation over time in the southern Black Sea Region Rivers in Turkey. About 83% of the total suspended sedime...

Abstract We started from a prey-predator model, where a periodic variation in the number of prey and predators is possible, without perturbation. We followed the line that periodically we carried out an overpopulation of prey. In general it is expected that this fact will increase the populations both of prey and of predator. We try to understand the way in which the overpopulation of prey can change the average number of prey and predators. In terms of application, such increase of the popu...

Freshwater marshes are the single largest source of atmospheric methane (CH4). Climate change and anthropogenic nitrogen (N) deposition can alter the production and oxidation of CH4 respectively and thereby also CH4 exchange. But there was little known about how N regulate key carbon (C) processes, like CH4 production and oxidation under freshwater marshland conditions. In this study, field-fertilization and incubation experiments were conducted to investigate the effects of four N-fertilizat...

On the other hand, because of the increasing people’s willingness to tourism and relaxation, it is necessary to select and introduce new regions for tourism. To do this, the application of relevant criteria can be a profitable method. The purpose of this study is to identify nature-based tourism activities and also site selection for them in Sisa...

The concept of “control” of the drinking water supply system (DWSS) is replaced by the concept of “under control”, in order to protect human health. The key factor of the WSP approach is the identification and mitigation or, if possible, the elimination of all factors that may cause a chemical, physical, microbial a...
