The Gulf of Maine/Bay of Fundy have documented increases in heavy metal pollutants. Whether species from distinctive water column zones (epipelagic, mesopelagic, demersal) are differently accumulating heavy metals and experiencing negative impacts on their physiology was the foc…

The spatial modeling of the petrochemical active regions in the Niger Delta (ND), Nigeria was carried out through the analysis exploration and extraction of geospatial data and resultant risk maps were generated. The pollutants assessed include; heavy metals, polychlorinated aro…
The electroremediation process requires much needed research work to be optimized for up-scaling and improving economic efficiency. This is particularly true when applying the technology to highly heterogeneous and complex mineralogy materials such as offshore sediments and muds…
In this work we studied trace element concentrations in four types of environmental samples. In the first part two types of applications of hair trace element analysis were studied: hair as a monitor for environmental exposure to heavy elements and age-related variations in hair…
The most critical factor for freshwater aquaculture in West Kalimantan, Indonesia, is water quality. Most of the waters available for aquaculture are coloured, brownish to black, due to high concentrations of metals associated with humic substances. To determine whether these wa…
Studies on urban storm water runoff quality indicate the presence of many different pollutants such as metals, toxic organics, and nutrients in rain water runoff. These pollutants are derived from different sources, and many factors are involved in their origin and transport. To…
In this study, the potential of fungi Aspergillus niger to remove cadmium, copper, lead and nickel ions from an aqueous solution was evaluated. Several pretreatment alternatives were investigated for enhancing metal removal capacity of live A. niger biomass. Cadmium, copper and …
Highway runoff, as a nonpoint source, may exert significant pollutant load on the catchment. Finding ways to mitigate nonpoint sources of pollutants is a matter of great concern for improving water quality. It was cited by the Environment Agency in 2005 that more than 80% of Eng…
The aim of this study was to develop a suitable monitoring protocol for mediated amperometric whole-cell biosensors for in situ assessment of heavy metals in soil. E. coli 8277, Pseudomonas 9773, Pseudomonas 9046 and Pseudomonas 8917 were screened as biosensor catalysts to selec…
The present experimental work is directed towards investigation of the electokinetically-enhanced transport of soil contaminants (specifically heavy metals) in clay media and offshore muds. The electrokinetic process is an emerging technology for in-situ soil decontamination, in…
Weak organic acids and/or their salts were tested as soil washing or flushing agents for the ex- or in-situ remediation of soils polluted by heavy metals. Three soils naturally with heavy metals were used for the tea. The three soils were characterized as a clay loam, loam and s…
The survey was conducted along 2,475 kilometers of tract in the South China Sea offshore East Peninsular Malaysia to evaluate the presence of placer gold, tin and heavy minerals, as well as sand resources. Geophysical methods were employed, consisting of high resolution seismic …
Water is essential for human subsistence. Stable freshwater supplies are needed as a source of food, drinking water, for transportation, recreation and economic development. Despite their recognized importance, anthropogenic activities have altered freshwater ecosystems around t…
