In this study, the removal of cadmium by using pumice coated with iron nanoparticles (INPs) from synthetic wastewater was investigated. The effects of parameters influencing adsorption: contact time (10-20 min), pH (3-9), initial cadmium concentration (25-125 mg l -1) and adsorbent dose (2-10 g l -1...

10 mg l -1 and the permeate flux behavior during dead-end stirred-cell filtration system using six type of commercially available loose and tight NF membranes (NP010, NP030, NF90, NF270, CK3001 and DS-5DK). The rejection of CIPRO and permeate flux value were evaluated according to the effects of...

In order to make assessments in understanding of physiological and genotoxic effects of imposing cadmium (Cd) on photosynthetic pigment contents along with the changes occurring in genetic material of Kalanchoe plants were used in relation to various Cd-treatments. Young plantlets were originated...

A high efficient nitrite based double-sludge system combining sequential denitrification and nitritation reactors has been developed to remove nitrogen from wastewaters containing high concentrations of ammonium. System performance was examined and also nitrous oxide (N 2O) emission was measured...

The study aims to evaluate soil erosion and investigate its spatial distribution by applying two empirical models, namely the Erosion Potential Model (EPM), also known as Gavrilovic method, and the RUSLE model at Venetikos River catchment, the largest and most important tributary of Aliakmonas River...

This study aims to measure citizens’ behavior intention (BI) in Environmental Impact Assessment (EIA) participation. An extended theory of planned behavior (TPB), which includes perceived government support and perceived environmental concern, is used as the predictor model. A total of 240...

Petroleum products are used in different forms in auto-mechanic workshops every day. Spent motor oil disposed-off improperly contains potentially toxic substances which can seep into the water tables and contaminate ground water. This study involved isolation and screening of bacterial species...

Raw municipal landfill leachate is extremely polluted wastewater and it regards as one of the drawbacks of the sanitary landfill treatment method. If the untreated landfill leachate is discharged to the natural environment, a great problem for the environment can be created, particularly for the...

Proper Hospital healthcare Waste Management (HCWM) is imperative for ensuring public health and environmental protection. In this context, three Prefectural hospitals of Mytilene, Agrinio, and Messolonghi, were studied with respect to planning and management of infectious wastes, cost, training of...

Today's world requires a change in how the use of different types of energy. With declining reserves of fossil fuels for renewable energies is of course the best alternative. Among the renewable energy from the wind can be considered one of the best forms of energy can be introduced. Accordingly...

This paper deals with prediction of the response of karstic springs by means of artificial neural networks (ANNs). A feed-forward back propagation ANN with three layers has been developed, to predict flow rates of two karstic springs, located at Rouvas area, Crete, Greece, using rainfall data as...

In the present work the physically based distributed rainfall–runoff modeling system, MIKE SHE, is used to simulate the surface runoff at a semi-mountainous impermeable area of Tavronitis River basin in Crete-Greece. The objective of this surface flow model is to develop an appropriate irrigation...

Wind Energy is one of the important sources of renewable energy. There is a need to prepare the availability of wind energy in the area where there is no measured wind speed data. For this type of situation, it seems to be necessary to predict the wind energy potential using such as wind speed using...

The contribution of integrated municipal solid waste (MSW) management systems to greenhouse gas emissions is not negligible, even though it is moderate compared with other anthropogenic activities. The main emission from landfills that accept biodegradable MSW is methane that escapes from the biogas...

The effects of various socioeconomic characteristics on Willingness-to-Pay (WTP) values for service attributes of Solid Waste Management (SWM) were evaluated in this study. The Stated Choice (SC) data collected from respondents in the Kolkata Municipal Corporation (KMC) area, India were analyzed...

The study examined the willingness of rural households to pay for sustainable management of community forests in Southwest Nigeria. The value elicitation format used was the dichotomous choice contingent valuation technique. The multistage random sampling technique was used in selecting 180 rural...

Thermogravimetric analysis combined with a mass spectroscopy detector was used to study the thermal stability of solid materials earmarked for processing by thermal desorption (for example during the amelioration of environmental damage). The objective of the study was to verify the applicability of...

This paper aims to investigate students’ awareness regarding the factors that affect the environmental quality in university classrooms. For this purpose a questionnaire survey was conducted, in which 314 undergraduate students of the School of Primary Education, Aristotle University of Thessaloniki...

The assessment of the air quality of indoor environment where people usually spend extended time periods, especially for sensitive population groups such as patients during their hospitalization, is of major importance. Ensuring a safe level of air quality in these indoor environment serves as an...
