The plants were grown in nitrogen-free Hoagland nutrient solution media containing 0.05%, 0.1%, 0.2%...

In the present investigation, an attempt for the reduction of six hazardous air Pollutants (HAPs) from diesel exhaust by different blends of diesel and biodiesel has been made. The synthesis of biodiesel has been done from Jetrofa, Linseed Castor and Karanja oils which are commonly used in the...

Presence of metals even at trace levels in natural waters pose sever health risks. Heavy metals are introduced to coastal and marine environments through a variety of sources and activities including sewage and industrial effluents where Black Sea is not different. However, metals behave differently...

The problem of reducing CO2 emissions from transport, a major contributor to the greenhouse effect, has become a growing concern for the scientific community and various international committees monitoring climate change. Energy savings in the transport sector are a key factor towards rational...

The objective of this study is to summarize studies and investigations and show a brief details of different technologies used for the treatment of petroleum wastewater. The wastewater from Petroleum industries and refineries mainly contains oil, organic matter and other compounds. The treatment of...

The objective of this study is to summarize studies and investigations about advanced oxidation processes (AOPs) used for the treatment of petroleum wastewater, which mainly contained oil, organic matter and other compounds. The big difference was shown in the specification of wastewater among the...

Abundance and availability of unconventional petroleum has led to intensified exploitation and exploration of the bitumen reserves. This has however led to environmental pollution. This study investigated the ability of Providencia stuartii isolated from heavy oil polluted soil to degrade natural...

Water resources are subjected to different pollution sources. Point source water pollution of surface water is an important issue when considering the limited surface water availability as well as the potential knock-on effects of this pollution on human health as well as habitat and land...

This paper present migration of some selected heavy metal (zinc, lead, copper, chromium and nickel) of roadside soil samples from along Ilesa-Akure highway with a view to assess the degree of contamination such soils contain and the likelihood that this contamination can be remobilized. Soil samples...

The growing number of polluted land areas makes the question of rehabilitation and safe/effective use of these areas increasingly imperative. For land polluted by heavy metals, the possibility of transferring the toxic pollutants to humans through the food chain further increases the importance of...

This work has exploited a Genetic algorithm for oil spill automatic detection. This is implemented to sequences of RADARSAT-2 SAR ScanSAR narrow single beam data in the Gulf of Mexico. The study shows that the implementation of crossover is generated an accurate oil slick pattern. This is confirmed...

The aim of this search was to identify the 101 top cited articles in the field of oil spill remediation. A search was conducted based on a database of the Web of Science included the journal citation reports from 1980 to 2013. The number of citations of the first 101 top cited articles is from 24 to...

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...

The objective of this study is to present an integrated stochastic approach for quantifying the risk of oil spill in marine waters and adjacent coasts. This was achieved via the effective cooperation between the National Technical University of Athens (NTUA) and the Bogazici University (BU) within...

A method is presented and preliminarily applied to the optimization of the allocation of oil-slick combating coastal stations in a coastal basin. The decision support methodology is based on the annual simulation of the circulation in the basin according to climatologic data, on the oil spill...

The unintended release of hydrocarbons into the environment can negatively impact human and animal health, and could further change the characteristics of soils. The aim of the present work was to investigate the rate of biodegradation at 10 and 20% diesel fuel in contaminated soil amended with 10%...

The combinations of H2O2/Fe+2, UV/H2O2/Fe+2 and UV/H2O2 process were investigated on treatment of oil recovery industry wastewater. Treatment of oil recovery industry wastewater, a typical high pollution strength industrial wastewater (chemical oxygen deman (COD): 21000 mg l-1, biological oxygen...

This work is aimed at evaluating the potentiality of adding a rhamnolipid biosurfactant in a petroleum-bearing soil. For this purpose, dehydrogenase activity and seed germination (Lactuca sativa) testes were performed before the biodegradation assays with different concentrations of rhamnolipid (1...

The present paper examines a small and deep (53 m) salty lake, as well as the adjacent harbor of Aghios Nikolaos (Crete). The survey was carried out in 1996. Physicochemical parameters indicated that the main characteristics of the system are the inflow of karstic water from underwater springs...

A climatological analysis of atmospheric concentrations of primary air pollutants in Athens, Greece, is presented for the 11-year period 1987-1997, since the automated local air pollution network operating by the Ministry of Environment started to record all conventional pollutants. The...

Energy use in Greek Industry, fuel mix changes and contribution of major sectors from 1960 to 2004 are presented and analysed. Energy related air pollutant emissions are estimated and presented too. Energy use in Industry has shown a growing trend. Residual fuel oil was the predominant energy form...

Recent oil tanker accidents in the sea are very serious, not only since they pollute the environment but also because they release heavy oil. The preparation of activated carbon from agricultural waste increases economic return and reduces pollution. On carbonized fibers, sorption capacity for...

The EU Directives and legislation by worldwide environmental authorities impose constantly lower levels for the airborne pollutant emissions of internal combustion engines towards the goal of zero emission vehicles. During the last decade, engine manufacturers, refiners and fuel companies invest...

In this paper, we present the estimate and results of measurement of air pollution in Béjaia city in Algeria. We used an enclosure of 0,80 m3 for the collection of gases directly on the outlet side of the tailpipe of the vehicles. A three-gas detector (MX21 plus), introduced inside the enclosure...

Effluents from five major textile industries in Kaduna (Nigeria) were characterized for a proposed central effluent treatment plant. Seven of the measured parameters exceeded the limit set by the Federal Ministry of Environment. Colour intensity exceeded it in all the samples (Mills 1 – 5) by about...
