soils around mining sites play a significant role in the transport and control of heavy metals in the environment. therefore, understanding the adsorption properties of soil is essential in solving pollution problems. the objective of this paper was to study zn(ii) adsorption onto sarcheshmeh copper mine soils. the adsorption isotherms of zn(ii) were studied. the langmuir isotherm indicated an ...

Background The interaction between microorganisms and heavy metals has been occurring since the beginning of life on the planet, 4 billion years ago, which allowed the biological evolution of resistance in systems and the survival of these microorganisms in environments containing high metals concentrations of metals [1]. Recently, a bioremediation review presented by Perpetuo et.al. [2] consid...

I. Bostan, Al. I. Cuza University, Faculty of Economics and Business Administration, Iasi, Romania. This paper is a synthetic analysis of the Romanian approach of an important underground resource, namely copper ore deposits. Certain elements of the international context have been introduced, highlighting the appreciation of the price of copper, as a result of increased demand from countries wi...

Acetic acid extracts of sediments from four Clark Fork River reservoirs,--Milltown, Thompson Falls, Noxon Rapids, and Cabinet Gorge--indicate that mining and smelting operations in the upper drainage have enriched metal concentrations throughout the river. Milltown Reservoir contains metal values over 10 times the background levels for copper, zinc, and arsenic. Enrichment over background decre...

To date, information concerning pre-Colonial metallurgy in South America has largely been limited to the archaeological record of artifacts. Here, we reconstruct a millennium of smelting activity in the Peruvian Andes using the lake-sediment stratigraphy of atmospherically derived metals (Pb, Zn, Cu, Ag, Sb, Bi, and Ti) and lead isotopic ratios (206Pb/ 207Pb) associated with smelting from the M...

The mining industry generates huge amounts of wastewater, containing toxic heavy metals. Treatment to remove heavy metals is necessary and recent work has been focused on finding more environmentally friendly materials for removing heavy metals from wastewater. Biosorption can be an effective process for heavy metal removal from aqueous solutions. Our objectives were to investigate the removal ...

Past mining and smelting activities have resulted in metal polluted environments all over the world, but long-term monitoring data is often scarce, especially in higher trophic levels. In this study we used bird (Parus major and Ficedula hypoleuca) excrement to monitor metal pollution in the terrestrial environment following 16 years of continuously reduced emissions from a copper/nickel smelte...

Determination of groundwater chemistry in the Strumica valley was essential given its widespread use for irrigation in the agricultural industry. 224 samples were collected form boreholes forming the dataset for the study. The groundwater chemical composition was examined for selected analytes: As, Sr, Mn, Ni, Cu, Zn, Mo, Ba, Pb, Na, Mg, Al, K, Ca, Ti, Li, Cr, Fe, U, CaCO3, Cl-, NO3, NH4, SO4 a...
