“…The enrichment of Cu, particularly in the mining vein margins, is probably because of increased Cu mineralization on the surface as result of the process of Au prospection as noted by Kesharvazi et al (2012) in Iran in an Au mining area. In a chromite mining area in Indonesia, an EF ranging from 0 to 3.37 was found, which is in the same range of those found at the two different soil depths at Serra Pelada, indicating Cu contamination (KRISHNA et al, 2013).…”

The large surface stacking volume of waste and tailings at the Serra Pelada gold mine, with a high content of potentially toxic elements (PTEs), has led to environmental damage in the area, which continues to this day and is yet to be measured. Total and available Cu, Mo, Pb, and Zn and an indicator index was formulated for soil contamination in the artisanal mining area of Serra Pelada, Amazônia, Brazil. To obtain these data, six soil samples were collected surrounding the lake formed from the mining trenches and one from a forest area outside the influence of mining activities. Metal solubilization and partial extraction were conducted by aqua regia and 0.5 mol L-1 HCl, respectively, followed by detection using argon plasma optical emission spectrometry. All PTEs showed total contents above the quality reference values for soils in the state of Para. The available fractions of Cu, Pb, and Zn were higher than the concentrations expected for Para in forest soils. The total Cu contents were above the value of prevention defined by the National Council of Environment. In general, there was Mo enrichment (41.0) > Cu (3.5) > Pb (1.4), indicating that the areas had been contaminated by PTEs a resulting from human activity.

“…Mining of metals from the ores and subsequent milling processes to remove the unwanted materials may also lead to the presence of such metals in soil and water around these areas (Stamatis et al 2001;Bird et al 2009). Distribution of heavy metals in water and soil nearby gold (Al-Hobaib et al 2013), iron ore (Jahanshahi and Zare 2015), uranium (Giri et al 2010;Elango 2013, 2014), chromite (Krishna et al 2013), antimony (Fu and Wei 2013) and polymetallic (Xu et al 2015) mines have also been examined.…”

Drinking water containing heavy metals above the maximum permissible limits cause potential risk to human health. The aim of this study was to determine the groundwater suitability for drinking use based on heavy metal concentration and the associated human exposure risk in an intensively irrigated part of the Cauvery river basin, Tamil Nadu, India. Sixteen heavy metals analysed were in the order of dominance of chromiumChromium and zinc were within permissible limits of the Bureau of Indian Standards for drinking water quality, and silver, lead and nickel were above limits in all the groundwater samples. In less than 50 % of the groundwater samples, aluminium, boron, cadmium, copper, iron and manganese exceeded their individual permissible limits. Heavy metal pollution index based on 11 heavy metals indicated that groundwater quality of this area is poor-to-unsuitable. Non-carcinogenic risk for humans due to ingestion of groundwater through drinking water pathway was very high for infants, children and adults. Silver, lead, nickel, cadmium and manganese largely contributed to the health hazard. Sources of heavy metals were identified to be geological and from human activities, i.e., application of fertilizers in agricultural fields, seawater intrusion due to intensive pumping for agriculture and wastewater from industries. Groundwater and surface water in this area pose large threat due to high levels of heavy metals, and it is necessary to avoid this water for drinking due to potential risk of health hazard. This study also demonstrated the application of HPI and human exposure hazard index to study the groundwater quality based on heavy metals' concentration.

“…Enriched PTEs in soil not only cause soil contamination but influence human health via the food chain [1,2,3,4,5]. To minimize the risk that arises from the high level of PTEs in soil, an examination of the extent and the level of contamination based on environmental assessment and monitoring is an important first step towards appropriate remediation [6,7]. The Korean Ministry of Environment (MOE) Standard suggests using an inductively coupled plasma atomic emission spectrometry (ICP-AES) analysis method to investigate the type and content of heavy metals in soil due to its high accuracy [8].…”

The use of portable X-ray fluorescence (PXRF) and inductively coupled plasma atomic emission spectrometry (ICP-AES) increases the rapidity and accuracy of soil contamination mapping, respectively. In practice, it is often necessary to repeat the soil contamination assessment and mapping procedure several times during soil management within a limited budget. In this study, we have developed a rapid, inexpensive, and accurate soil contamination mapping method using a PXRF data and geostatistical spatial interpolation. To obtain a large quantity of high quality data for interpolation, in situ PXRF data analyzed at 40 points were transformed to converted PXRF data using the correlation between PXRF and ICP-AES data. The method was applied to an abandoned mine site in Korea to generate a soil contamination map for copper and was validated for investigation speed and prediction accuracy. As a result, regions that required soil remediation were identified. Our method significantly shortened the time required for mapping compared to the conventional mapping method and provided copper concentration estimates with high accuracy similar to those measured by ICP-AES. Therefore, our method is an effective way of mapping soil contamination if we consistently construct a database based on the correlation between PXRF and ICP-AES data.
