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 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…
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 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 …
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…
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 …
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…
The pollution of soils by trace elements and heavy metals is a grave environmental problem, mainly due to their toxic and accumulative properties. The levels of lead, cadmium, copper, chromium, nickel, zinc and cobalt, extractable with 0.5 M acetic acid, have been determined in …
