“…Chemical interactions between soil and As are important to understand its fate in the environment and choose the suitable management strategy (Bolan et al 2014 ). These last years, part of the research concerned remediation (Gonzalez-Fernandez et al 2011 ;Drouhot et al 2014 ;Jana et al 2012 ;Flakova et al 2012 ). In this context, the better understanding of the fractionation and the potential of mobilization of arsenic is required and helpful to improve the efficiency of these technics.…”

The environmental assessment and management of historical mining sites contaminated with various inorganic species require a better knowledge of pollutant-bearing phases. Among elements present in mining soils, arsenic is a toxic metalloid with potential high content and high mobility capacity into the environment. The objective of this paper was to investigate the mobility and fractionation of arsenic (As) in a highly As contaminated soil (ca. 3 wt%). The soil was collected from an old gold mining site in France, where mining activities and smelting processes of gold ores took place.

“…Some other previous studies along this area were focussed on the characterization of heavy metals content at the alluvial plain and the transfer of these metals both to vegetation and to the water media (Gonzalez-Fernandez, Queralt et al 2010b;JimenezCarceles, et al 2008;Alvarez-Rogel et al 2007).…”

The assessment of metals dispersal in polluted mining areas is a very complex issue, usually needing data from several analytical techniques in a joint approach. The present work focuses on the impact of the mining activity on lowlands alluvial plain sediments from an ephemeral creek, their role as source or sink of pollution and the spatial distribution of metals within the zone. In-depth distribution of elements (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, S, Ti and Zn) coming from mining activities was investigated by using X-ray fluorescence techniques and their mineralogical form using X-ray diffraction. A 2-D electrical resistance tomography field survey was carried out throughout at the creek bed to interpret the potential relationships between chemical, mineralogical and geophysical parameters. The application of leaching procedure (DIN 38414-S4 test) allows us to know the sediment's heavy metals hazard and their potential mobility when changing redox conditions. From the results it was found that redox process of sulphur and the presence of carbonate influence the distribution of metals along the profile. In the present work, the precipitation of carbonates seems the most important process, especially for elements such as Zn and Mn. Secondary precipitation of sulphides enables the trapping of metals at sulphur-rich levels.

The north east of Tunisia ore deposits (Hammam Zriba) contain a large amount of fluorides constituting a risk of environmental pollution as well as risks to human and animal health. The aim of our work was to assess the levels of fluorides in the water and blood of sheep in the east of Tunisia region. This analysis study included 78 water samples and 60 blood samples taken during 3 days in the year 2019, from a sheep herd at Hammam Zriba delegation. The determination of fluorine concentration in the samples was carried out by potentiometry with a selective electrode type ISE combined Fluoride perfectION™. High Fluoride concentrations were found at a mean of 1.62 ± 1.18, 1.45 ± 0.98, and 2.65 ± 1.61 mg/l, respectively, in running, deep, and stagnant waters. In addition, 83.3% of the animals reared within 400 m of the study area had elevated fluoride levels in the blood exceeding the usual values (fluoremia> 0.15 mg/l). The concentration of fluoride in the blood of the animals decreases with increasing distance from the mine.
