Research relevance. Phosphate mining activities are one of the main sources contamination by heavy metals since they harmfully affect soil and lead to degradation ecosphere. aim. This study aims at characterizing evaluating metallic soils in vicinity Djebel Onk mine town Bir El Ater (Wilaya Tébessa) eastern Algeria, particularly focusing on estimating spatial variability this extent contaminate...

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 ...

in the present investigation flocculation of dissolved cu, zn, pb, ni and mn in a series of mixtures with salinities ranging from 1.5 to 9.5% during mixing of talar river water with the caspian sea water was studied. the flocculation trend of zn (87.22%) >mn (45.31%) >pb (39.09%) >cu (36.58%)>ni (12.70%) indicates that cu, zn, pb and mn have non-conservative behavior and ni has relatively conse...

Background & Aims of the Study: Regarding to development of industry, soil contamination has become a serious problem in many countries, such as Iran. The aim of the present work was the illustration of the accumulation of potentially harmful trace elements and the potential risk which is posed to human health in surface soils of three industrial estates of Aran-o-Bidgol city, Isfah...

Stream sediments from the mining and smelting district of Príbram, Czech Republic, were studied to determine the degree, sources and dispersal of metal contamination using a combination of bulk metal and mineralogical determinations, sequential extractions and Pb isotopic analyses. The highest metal concentrations were found 3-4 km downstream from the main polymetallic mining site (9800 mg Pb k...

The investigation was carried out on a small pond situated on a recent mine spoil at Bolesław in the Olkusz region with Zn-Pb ore deposits. Water of the pond had pH 7.2-8.5 and low concentrations of heavy metals. Concentrations of Pb (487 μg g( - 1)) and Zn (1,991 μg g( - 1)) in the sediment were very high and potentially could lead to toxicological effects. In the pond, 48 taxa of macroinverte...

This investigation was undertaken to determine the atmospheric pollution with heavy metals due to copper mining Bucim near Radovis, the Republic of Macedonia. Moss samples (Hyloconium splendens and Pleurozium schrebery) were used for biomonitoring the possible atmospheric pollution with heavy metals in mine vicinity. Sixteen elements (Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mn, Na, Ni, Pb, Sr, a...

In order to better understand the role of coal gangue in potential environmental and ecological risks, the leaching behavior of trace elements from coal gangue has been investigated in an open-cast coal mine, Inner Mongolia, China. Four comparative column leaching experiments were conducted to investigate the impacts of leaching time, pH values and sample amount on the leaching behavior of trac...

Introduction Phosphate-Induced Metal Stabilization (PIMS) using Apatite II stabilizes a wide range of metals, especially Pb, Cd, Zn, U and Pu, in situ or ex situ, by chemically binding them into new stable phosphate phases and other low-solubility phases that are stable over geologic time. The concept resulted from paleochemical oceanographic and chemostratigraphic studies, in the 1970s and 198...

The aim of the present study is to evaluate the potential ecological risk and trend of soil heavymetal pollution around a coal gangue dump in Jilin Province (Northeast China). The concentrations of Cd, Pb, Cu, Cr and Zn were monitored by inductively coupled plasma mass spectrometry (ICP-MS). The potential ecological risk index method developed by Hakanson (1980) was employed to assess the poten...
