“…On the other hand, PHE bioavailability can be dictated by various physicochemical factors (e.g., pH, Eh) as well as physiological variations (Barkouch et al, 2007;Kabata-Pendias, 2011;Skordas & Kelepertsis, 2005;Yang et al, 2004;Zhao et al, 2013Zhao et al, , 2014. For these reasons, in this study the standard indices have been coupled with a more comprehensive calculation, the robust compositional soil contamination Index (RCCI) which tries to identify the pollution level taking into account the compositional character of the data (Petrik et al, 2018a;Reyes et al, 2019).…”

Gold mining activities are undertaken both at large and artisanal scale, often resulting in serious ‘collateral’ environmental issues, including environmental pollution and hazard to human and ecosystem health. Furthermore, some of these activities are poorly regulated, which can produce long-lasting damage to the environment and local livelihoods. The aim of this study was to identify a new workflow model to discriminate anthropogenic versus geogenic enrichment in soils of gold mining regions. The Kedougou region (Senegal, West Africa) was used as a case study. Ninety-four soil samples (76 topsoils and 18 bottom soils) were collected over an area of 6,742 km2 and analysed for 53 chemical elements. Robust spatial mapping, compositional and geostatistical models were employed to evaluate sources and elemental footprint associated with geology and mining activities. Multivariate approaches highlighted anomalies in arsenic (As) and mercury (Hg) distribution in several areas. However, further interpretation with enrichment factor (EFs) and index of geoaccumulation (IGeo) emphasised high contamination levels in areas approximately coinciding with the ones where artisanal and small scale mining (ASGM) activities occur, and robust compositional contamination index (RCCI) isolated potentially harmful elements (PHE) contamination levels in very specific areas of the Kedougou mining region. The study underlined the importance of complementary approaches to identify anomalies and, more significantly, contamination by hazardous material. In particular, the analyses helped to identify discrete areas that would require to be surveyed in more detail to allow a comprehensive and thorough risk assessment, to investigate potential impacts to both human and ecosystem health.

“…From washed hair [2,9] with nitric acid 10% four times for 10 min then rinsed with acetone three times for 10 min and dried, a test portion of approximately 50 mg is weighed exactly and then introduced into a polystyrene tube and added with 1 mL of nitric acid 8N [3,10,11]. The sealed tube is kept at room temperature for 24 hours; during this preliminary phase, the bulk of the sample is dissolved in the acid.…”

The disposal of urban or hospital waste in open landfills is the easiest way to throw back of them without environmental concerns. MTEs (Metal Trace Elements) are the most toxic mineral elements. This study evaluates the impact of MTE on a neighboring human population or playing near a municipal dump. Two panels were composed of adult men and children (males under sixteen years old). Four trace metal elements were analyzed: copper, lead, cadmium and zinc. The site of the study was the municipal waste dump in Marrakech (Morocco). The results reveal abnormal concentrations of these MTEs in blood and hair of adults and children.

“…It has good microbiological and biological properties in general and as such requires minimal treatment. Actually, a variety of human activities -notably industrial and mining process -have been responsible for the wider diffusion of heavy metals into this type of water [10].…”

A New Approach for Understanding Lead Transfer in Agricultural Soil

Abstract: Surface water is frequently contaminated by the trace metals, in particular lead and zinc, produced by mining activities. The infiltration of this water is likely to pollute surface soils and ground water.
