AbstractAromatic volatile organic compounds (VOCs) proved to have enhanced polluting behavior upon the atmosphere and human health. Their catalytic destruction is an alternative for environmental pollution reduction in the case of gaseous emissions with low contents of VOC.In this paper, an experimental study is presented, concerning the conversion of benzene and its mono-halogenated derivatives on SCR-DeNOx (V2O5-WO3/TiO2) commercial catalyst, specific for the reduction process of nitrogen oxid...

AbstractDuring the transition to a market economy, many countries with a planned economy in Central and Eastern Europe face similar challenges when the established socio-economic systems and infrastructures deemed inefficient in a market economy. Also new issues are being raised by the trends of globalization and the vision of sustainable development. In the energy sector the challenges raised by the Kyoto Protocol and its implementation mechanisms are especially interesting, because they are in...

AbstractThe objective of the paper is to present sustainability indicators for municipal solid waste management (MSWM). Sustainability implies environmental, economic and social acceptance. The complexity of the system-in-focus requires the employment of a systems (or cybernetic) approach: Acceptance implies clear objectives, from a specific point of view (here, the viewpoint of the municipal administration is taken), over a time horizon covering at least two generations, a life-cycle considerat...

An attempt has been made to develop Water Quality Index (WQI), using six water quality parameters at riverside stations located in the vicinity of temples of Dakshina Kannada district, Karnataka, South India. Rating curves were drawn based on the tolerance limits of inland waters and health point of view. Bhargava WQI method and Harmonic Mean WQI method were used to find overall WQI along the stretch of the river basin. Five point rating scale was used to classify water quality in each of the st...

The use of gasoline oxygenated with MTBE (methyl tert-butyl ether) reduced significantly air pollution (16 - 23% lower emissions of CO and 18% lower emissions of unburned hydrocarbons) but increased water pollution. There is no European or national regulations for MTBE in drinking water except for Denmark, which has set a limit value of 30 Âľg/ L for MTBE. USEPA proposed a maximum concentration of 20- 40 Âľg/L. This paper is a review with 70 references on the MTBE production, use, properties and...

Investigation - the process of identifying the presence of pollutants in the environment, the spatial dispersion of these pollutants, the level of their concentration, as well as the analysis of the environment’s structure. The steps that were follow...

Abstract Increasing the solar energy conversion into electrical or thermal energy represents an European and national priority, because it offers clean alternatives to the use of fossil fuels, in no pollutant systems, based on photovoltaic modules and solar collectors. The global solar radiation is the most important factor affecting the amount of energy produced by a PV module. In direct connection with the change in the solar energy conversion, the TR - Loss Coefficient (Tr??bungsfaktor) is...

Abstract The cleanup of environmental pollution involves a variety of techniques, ranging from simple biological processes to advanced engineering technologies. Cleanup activities may also address a wide range of contaminants. Technologies to remediate contaminated soil fall into two principal clean-up approaches: in-situ (which is always done onsite), or ex-situ (which can be done on- or off-site). In-situ treatment deals with contamination without removing material from the ground, while ex...

Five new aryloxyalkylcarboxylic acid derivatives (diazoaminoderivatives) are studied for their thermal behavior by applying a coupled TG-FTIR technique over the (30-400 oC) range in correlation with the environmental impact of gaseous species resulting by thermal degradation. These compounds are of a particular practical significance since they show a high biological potential as agrochemicals, such as pesticides (herbicides, acaricides, fungicides, growing stimulators etc.). This is why the pap...

Abstract Oil contamination has been one of the most common environmental pollution due to its threat to both human health andecosystems. It is difficult for the application of conventional chemical analysis to detect oil contamination in-situ, estimatebioavailability and rapidly assess the environmental risk. In this study, two bioreporters were employed for the rapid and directdetection of oil content and genotoxicity in a cutting oil contaminated site in China. Acinetobacter baylyi ADPWH_...

Magnetic nanoparticles (MNPs)functionalization as bioreporters can enhance the ability for biosensing in complex contaminated samples such as soils, and theimmobilization of bioreporters will promote the detection of gas and online monitoring.

AbstractZarshuran As-Au deposit is the major ore deposit in northwest of Iran. Having been exposed to weathering, the accumulatedmining waste is consumed to deteriorate regional soil and water quality. Accordingly, 11 composite surface soil samples werecollected to evaluate the metallic pollution. Mean concentration of elements As, Sb, Hg and Zn were measured to be 234.9, 19.6,24.2 and 476.7 ppm, respectively. In comparison with mean earth crust and local guidelines for agricultural soil, the sa...

This paper has two objectives: first to show how a set of global measures can be obtained using techniques from network theory, in particular how the spectral analysis of the adjacency and Laplacian matrices allows us to obtain a characterization of global ...

The main objective of this research was to evaluate the environmental impact generated by municipal solid waste during its collection, transportation, treatment and processing in the south-west region of the department of Norte de Santander, Colombia, by means of Life Cycle Assessment (LCA). Three strategies for waste management were considered: the current baseline situation, wherein 100% solid waste was taken to the landfill; plus, an optimistic and a pessimistic scenario in which solid was...

Although considered a rare disease, endemic to low-income regions and unsanitary environments, leptospirosis is still encountered in some parts of Romania, in both rural and urban environments. Its specific pathways of transmission caused it to be a threat to people working with animals, pest control, farmers or those whose jobs place them in the presence of waters, sewers or in flooded areas.
