Fire agencies worldwide apply millions of gallons of fire suppression chemicals on a broad array of ecosystems. These chemicals are considered to have minimal effects on the health of people who might be exposed to them. Only incidents of skin and eye irritation have been reported as a result of...

The present studies aimed to obtain clean fuel combustion and get detailed information about the processes that determine the electric field effect on NOx formation in flame channel flows. The experimental studies demonstrate that the interaction between the radial electric field and the flame...

The aim of this paper is to identify the factors that have influenced changes in the amount of carbon dioxide (CO2) emitted from the Greek manufacturing sector as a whole and from three representative subsectors. By means of an algebraic decomposition method the changes recorded during the period...

Air pollution related problems, such as acidification, air quality and ground-level ozone, are recognized as some of the important problems facing the people of the Czech Republic, whose health is damaged by impacts of air pollutants. Also the impacts of these air pollutants on human health, forests...

Testing was conducted with anionic diphenyloxide disulfonate (DPDS) surfactants (C12 and C16 alkyl moieties) with naphthalene in aqueous systems and phenanthrene in soil systems to investigate the influence of these surfactants on biodegradation of hydrocarbons. A potential for enhancement in the...

Pump-and-treat (P&T) is one of the most common methods for remediation of groundwater contaminated by hazardous wastes. However, this method suffers from serious disadvantages, due a series of subsurface processes. Using experimental data and mathematical model simulations, the role of sorption/...

The present work argues that sustainable tourism is essential to the long-term survival of the tourism industry in Europe. Sustainable tourism may be regarded as a means of redressing economic imbalances between European regions and nations without producing adverse environmental, social and...

This study was conducted to assess the removal efficiency of Di-n-butyl phthalate (DnBP) from aqueous medium using the photo-Fenton process. The Fenton's reagent that consists of a mixture of hydrogen peroxide (H2O) and ferrous ions (Fe2+) was used to generate the hydroxyl radical (OH0) that attacks...

The paper discusses a methodology for integrated municipal wastewater management. In compliance to the EU Directive 91/271, there is a legal binding to ensure that all agglomerations with populations over 2000 are provided with wastewater collecting system and adequate treatment. The conditions for...

The sustainable management of water resources often requires the identification of wastewater as a valued source of water. Although the benefits of wastewater reuse and reclamation have increased significantly in Europe because of the advances in effectiveness of wastewater treatment and...

This study was conducted to evaluate the surface and subsurface drip irrigation (SDI) application effects on sugar beet crop performance, under two levels (100% and 80%) of water application depth. The experimental design was a split plot with four replications. Laterals were set every second crop...

It is well known that the toxicokinetics (i.e. absorption, distribution, metabolism and excretion) of mercury is highly dependent on the form of mercury to which a receptor has been exposed. The aim of this paper is to summarize the available health effects information for mercury and mercury...

Water resulting from the dewatering process of petroleum storage tanks was treated in a pilot separator to investigate the effectiveness of the combined action of a coagulant (aluminum sulfate) and a cationic flocculant (NALCO 71403). Central composite design of experiments was used to construct...

The changes in greenhouse gases and aerosols emissions are expected to lead to regional and global changes in temperature, precipitation, and other climate variables. The degree to which human conditions and the natural environment are vulnerable to the potential effects of climate change is a key...

The present work investigates the hydrotreating process of a diesel in order to achieve lower sulphur and aromatics content. The entire work was performed in a Hydrodesulphurization (HDS) pilot plant unit located in Chemical Process Engineering Research Institute (CPERI). For the tests, a commercial...

Atmospheric aerosols have been implicated in human health effects, visibility reduction in urban and regional areas, acidic deposition, and altering the earth’s radiation balance. A major goal of scientific research for the last fifteen years has been the development of the necessary models, using...

Chlorination of drinking water leads to the formation of a variety of Disinfection By-Products (DBPs) that may have adverse health effects on humans. Research on this subject has been continued and new epidemiological and toxicological studies have been conducted. This review summarizes factors...

A mathematical model is presented, consisting of a two-layer, finite difference hydrodynamic submodel and a compartmental water quality sub-model. The model is calibrated with field data. Then, it is applied to Southern Evoikos Gulf, an open coastal water body of particular ecological significance...

The activity and selectivity of Pd catalysts supported on YSZ and dosed with different amounts of Na promoter has been investigated for the reduction of NO by alkenes (C3H6) or alkanes (CH4). It is found that Na strongly promotes the reduction of NO by C3H6. Rate increases by an order of magnitude...

The photocatalytic degradation of protocatechuic acid, a biorecalcitrant polyphenolic compound typically found in olive processing and wine distillery waste waters, has been investigated in aqueous heterogeneous solutions containing semiconductor powders (TiO2, ZnO) as photocatalysts, both in the...

The toxic effects of the herbicide Atrazine, its degradation products deethyl-atrazine and deisopropylatrazine, and the herbicide metolachlor were examined in unialgal cultures of Chlorella fusca var-fusca. The toxicity of a mixture of atrazine and metolachlor was also evaluated using the same...

Effective eco-environment rehabilitation is an essential policy issue in arid oasis ecosystem. Since 2007, a policy which focuses on environment restoration and protection was implemented in the Shiyang River Basin of Gansu Province, China. Using Minqin oasis as a case, the effectiveness of policy...

Sites co-contaminated with organic and metal pollutants are common and considered to be a more complex problem, as the two components often have a synergistic effect on cytotoxicity. This study investigated the dissipation mechnisms for pyrene in cadmium co-contaminated soil in which maize (ZEA MAYS...
