Soil Contamination by Trace Metals: Geochemical Behaviour as an Element of Risk Assessment
Trace metals occur naturally in rocks and soils, but increasingly higher quantities of metals are being released into the environment by anthropogenic activities. Metals are chemically very reactive in the environment, which results in their mobility and bioavailability to living organisms. People can be exposed to high levels of toxic metals by breathing air, drinking water, or eating food tha...

Concentration of Trace Metals in Boreholes in the Ankobra Basin, Ghana
Analysis of trace metals in groundwater from the Ankobra basin revealed high levels of iron, manganese and aluminium. Approximately 40% of boreholes had total iron concentration exceeding 1000 μg l-1 (maximum WHO permissible limit). Aluminium concentration varied from 0.1 μg l-1 to 2510 μg l-1 with a median value of 10.0 μg l-1. Approximately 20% of the boreholes had aluminium concentration exc...
متن کاملToxic and Trace Metals in Thane Creek
Trace metals are intrinsic, natural constituents of our environment. Apart from the natural sources, several anthropogenic ones also contribute to metal concentrations in the environment. Some of the anthropogenic sources of the metals in the environment are: mining, smelting, production and use of the compounds and materials containing the metals, burning of fossil fuels, waste dumping and lea...
