The present study deals with the problem of soil contamination risk assessment for a region being actively impact by the routine production of Kremikovtzi metallurgical plant near Sofia, Bulgaria. Although the production is now cancelled, the soil pollution is present and needs careful assessment...

In this article, the technical feasibility of various commercial adsorbents (activated carbon, clinoptilolite, and their mixture) for removal of Cr(total) ions from waste printing developer has been represent. Experimental tests were performed in laboratory batch mode. The adsorption data were...

The effect of temperature increase and more specifically its upper and low level correlates on soil microbial biomass, activity and N-cycle variables was studied in a Mediterranean shrubland. Experimental manipulation succeeded in establishing three treatments which, in comparison with the monthly...

This paper presents the results of an investigation that aimed to evaluate the efficiency of various inorganic coagulants and organic polymers to combat filamentous foaming and bulking problems, caused by the proliferation of M. parvicella and/or Gordona amarae. The duration of the investigation...

This study concerns a protected area in northern Greece and examines how local people’s occupation influences their perception of environmental impacts and their views and information about the area. The target groups were local residents that (a) were employed in the primary sector, (b) were...

The adsorption of Basic yellow 2 (BY2), from aqueous solutions onto Granular activated carbon (GAC) and its adsorption kinetics at different concentrations, GAC masses, initial pH values and temperatures were studied. The adsorption process was followed by an on-line spectrophotometric analysis...

Environmental Sensitivity Index (ESI) mapping of Atlas Cove, Lagos, Nigeria was carried out with the objective of producing an Environmental Analysis Index map of the shorelines. The study integrated methodologies developed by National Oceanic and Atmospheric Administration (NOAA) and Nigerian Oil...

The new Air Quality Directive (2008/50/EC) encourages the introduction of modelling as a necessary tool for air quality assessment and management. Towards this aim, a new Air Quality Management System (AQMS) has been developed and installed in the Department of Labour Inspection of the Republic of...

Polycyclic Aromatic Hydrocarbons (PAHs) are one of the major categories of pollutants entering the marine environment and finally accumulating in the sediments. Their occurrence raises major concerns for human health, especially during coastal activities (bathing waters, aquaculture, etc), having...

Trihalomethanes are a major class of chlorination by-products in drinking water. They are formed when chlorine reacts with bromide (Br-) and natural organic matter (NOM) in source waters. Toxicology studies have shown all THMs to be carcinogenic or to cause adverse reproductive or developmental...

Global warming is one of the most serious challenges facing humankind as it has the potential to dramatically modify the living conditions of future generations. In order to reduce the emission of greenhouse gases, most countries are implementing regulations aimed at reducing their dependence on...

Human thermal comfort conditions were determined in two mountainous regions of Greece, Gerania mountains (MG) in east continental Greece, and mountainous Nafpaktia (MN) in west continental Greece. Both regions are unexploited with considerable tourist potential. Four sites in each study region were...

Composting of organic solid wastes is gaining in importance worldwide, in the frame of integrated municipal solid waste management and, in particular, the diversion of biodegradables from landfilling. At the post-consumer stage, this can be achieved by composting practices ranging from large-scale...

Activated carbon (AC) is currently being used to treat polychlorinated biphenyl (PCB) contaminated field sediment. In the presence of sediment, the sorption capacity of AC for PCBs can be reduced. In this study, sorption attenuation of AC is investigated using previously published data from 5...

Sorption of toxic metal ions (Ni2+, Cu2+ and Cd2+) from Hevea brasiliensis bark carbon (HBBC) was carried out at 30±1 °C under various experimental conditions. Effect of various process parameters has been investigated by following the batch adsorption technique at 30 +1°C. The percentage removal...

Activated carbon (AC) amendment for reduction of contaminant exposure in polluted soils and sediments has recently emerged as a promising remediation technique. Here, we provide a short overview of the state-of-the-art in activated carbon (AC) amendment to such sites. Most studies not only in...

The stringent new regulations to lower sulfur content in fossil fuels require new economic and efficient methods for desulfurization of recalcitrant organic sulfur. Hydrodesulfurization of such compounds is very costly and requires high operating temperature and pressure. Adsorption is a non...

The objective of this pilot-study is to evaluate the Granular Activated Carbon (GAC) performance for the removal of specific disinfection by-products (DBPs), trihalomethanes (THMs) and haloacetic acids (HAAs), from Athens drinking water. For this purpose, a GAC pilot filter-adsorber was operated in...

Green waste (leaves, grass and shredded twigs) was composted for 5.5 months in a wooden composting bioreactor, of 1 m3 capacity, using both passive convective aeration, facilitated by the design of the bioreactor, and manual turning. Temperature was measured daily, while samples were analysed for...

The use of Geographical Information Systems (GIS) for Landfill Sitting is studied. The necessary spatial information required to determine the candidate sites for any type of terrestrial area (Community/Prefecture/Region/Country) is examined. This spatial information is then used for site selection...

Consumption of plastic products has increased dramatically over the past few decades. This trend results in the generation of a vast waste stream that needs to be properly managed to avoid environmental damage.
