Citizen concerns about environmental management practices will usually lead to public attention and legislative proposals. This paper intends to assess the behaviour of potential environmental polluting industries. In order to accomplish this objective, a survey composed of twenty-five questions was...

During the production of cephradine (a main constituent of anti-osmotic drug) a large quantity of concentrated effluent was produced. The main polluting compounds in this effluent are osmotic drug, acetic acid and ammonia. The main objectives of the study were to assess the toxicity in terms of...

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 development of a conceptual site model (CSM) is an invaluable tool used for assessing and planning remedial actions at a contaminated site. The CSM incorporates site-specific, hydrogeologic and geochemical information to identify contaminants of concern, sources of pollution, environmental...

The vertical migration velocity of radionuclides and the ability of soils components to immobilise them, as the most important parameters of natural-restoration, was studied. The Dose Equivalent Rate (DER) reduction of external ã-radiation was studied in order to assess its impact on human health...

A model and spreadsheet-based numeric approximation for computing risk-based soil cleanup level to be protective of petroleum-contaminated soil to an indoor air exposure pathway is presented. The algorithm incorporates traditional equilibrium partitioning equations (3 or 4-phase) for the...

In recent years, a considerable research effort has been devoted to Life-Cycle Assessment (LCA). However, most of the work has been focusing on improving the methodology as such and providing guidelines for carrying out LCA studies. Much less effort has been dedicated to the exploration and analysis...

Accumulation of airborne pollutants in vegetation is an important initial step in the uptake process of the terrestrial food web, providing direct and indirect routes by which biota and, eventually, humans are exposed to chemicals. A set of algorithms for estimating atmospheric pollutant...

Electricity generation is the single most important sector in which CO2 reductions are achievable, with advanced generation technologies available and the existence of a centralised production structure, if compared to the transport or the industrial sector. It is a market undergoing a radical...

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...

Life cycle assessment (LCA) is a technique for holistic environmental assessments of products and processes. The unique feature of this methodology is its focus on the entire life cycle of a product, from raw material extraction to final disposition. In order to assess the role of LCA in...

In the present work, Fourier Analysis is applied to the mean monthly NOx concentrations of the period 1989-1999, for a network of 7 stations. Treating NO and NO2 as a single primary pollutant, we succeeded the assessment of NOx concentrations. The main causes of NOx emissions in urban areas are the...

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...

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...

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...

This paper presents a methodology of evaluating management options for dredged sediments on the basis of an array of characterization tests and gives an example application for the sediments of Piraeus port. A conceptual model is proposed to guide selection among three management options. The model...

The main objective of this work is to apply the hedonic pricing method using the methodology of spatial econometrics in order to assess the economic value of irrigation water, as one of the individual attributes of the value of agricultural land parcels. Most of the agricultural land’s value...

Odour emissions are a major environmental issue in sanitary environmental engineering plants, due to the increasing number of complaints being made by the exposed population. The particular and complex nature of the substances considered to be the cause of the odour impact, their variability in time...

In recent years many researchers show a high interest in co-digestion, simultaneous anaerobic decomposition of a homogenous mixture of at least two biodegradable waste. Anaerobic codigestion is reported to offer several benefits over digestion of separate materials, such as increased cost-efficiency...

In 2006, California passed legislation establishing the first State Biomonitoring Program in the USA. The main goals are to: 1) Determine levels of environmental chemical contaminants in a representative sample of Californians; 2) Establish trends in the levels of these chemicals over time; 3)...

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...

Earthworm avoidance response is a new tool for rapid and efficient screening of potentially toxic substances added to soil environments. This technique was used to determine if five common, ecologically different earthworm species (Allolobophora chlorotica, Aporrectodea longa, Aporrectodea...

Environmental, economic and strategic reasons are behind the rapid impulse in the deployment of renewable energy sources that is taking place around the world. In addition to overcoming economic and commercial barriers, meeting the ambitious objectives set by most countries in this field will...

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...

Presented are the results, with emphasis on the situation in Greece, of the ENHIS-2 project “Establishment of Environment and Health Information System Supporting Policy Making”. The information system is based on a set of Environmental Health Indicators developed and updated by the project...
