“…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.

One of the most important resources for drinking water is groundwater. Recently, the quality of groundwater has been endangered due to several reasons, including human activities, vast agricultural activities, and the discharge of industrial wastewater containing nitrogen (N) and heavy metals. For this study we investigated the values of NO 3 , NO 2 , and some heavy metals and analyzed the groundwater of the Ardabil Aquifer area in wet and dry seasons. For this purpose we evaluated 76 wells in the study area. In order to analyze the results we used World Health Organization (WHO), U.S. Environmental Protection Agency (EPA), and Institute of Standard and Industrial Research of Iran (ISIRI) standards. The results indicated that, according to WHO and ISIRI, 10.5% of wells and, according to the EPA, 69.7% of wells have NO 3 above the standard level in the wet season, but in the dry season, according to WHO and ISIRI,29% and, according to the EPA, 80.6% of the wells have NO 3 above the permissible level. However, according to all standards, NO 2 values are less than the permissible level for drinking consumption. In terms of evaluation criteria of the simultaneous presence of NO 3 and NO 2 in drinking water (K), 29% of wells in the dry season and 13.15% of wells in the wet season have NO 3 and NO 2 problems. In order to find an appropriate interpolation method and zoning parameter of NO 3 and NO 2 , different interpolation methods were evaluated and Kriging method with the lowest error was chosen for zoning the parameters. According to zoning maps, in the wet season the Namin and south Ardabil areas, which have the most drinking water wells, contain values of NO 3 above the permissible levels, whereas the values of NO 3 are at the mediocre level in the dry season. In addition to NO 3 and NO 2 analysis, the evaluation of heavy metals pollution indices in the aquifer include: heavy metal pollution index (HPI), heavy metal evaluation index (HEI), and contamination degree (C d ). Generally, according to the EPA, in terms of NO 3 and NO 2 pollution, Ardabil aquifer is in an undesirable condition, and according to WHO and ISIRI standards, this area has a mediocre level of undesirable condition. According to HPI and C d indices, most parts are in a high class of heavy metal pollution, as well.

“…Previous studies conducted at GEG were directed at understanding mineralization (Babaki and Aftabi 2006; Heydari 2008; Mücke and Golestaneh 1982), mineralogy and petrography (Mücke and Younessi 1994), mining method of the ore bodies (Azadeh et al 2010; Saeidi et al 2014), environmental impact assessment (Phillips 2013), and groundwater characteristics (Jahanshahi and Zare 2015). However, no research has been documented about PM mineralogy and associated health effects around GEG.…”

Concentrations of total suspended particulate matter, particulate matter with aerodynamic diameter <2.5 μm (PM2.5), particulate matter <10 μm (PM10), and fallout dust were measured at the Iranian Gol-E-Gohar Mining and Industrial Facility. Samples were characterized in terms of mineralogy, morphology, and oxidative potential. Results show that indoor samples exceeded the 24-h PM2.5 and PM10 mass concentration limits (35 and 150 μg m−3, respectively) set by the US National Ambient Air Quality Standards. Calcite, magnetite, tremolite, pyrite, talc, and clay minerals such as kaolinite, vermiculite, and illite are the major phases of the iron ore PM. Accessory minerals are quartz, dolomite, hematite, actinolite, biotite, albite, nimite, laumontite, diopside, and muscovite. The scanning electron microscope structure of fibrous-elongated minerals revealed individual fibers in the range of 1.5 nm to 71.65 μm in length and 0.2 nm to 3.7 μmin diameter. The presence of minerals related to respiratory diseases, such as talc, crystalline silica, and needle-shaped minerals like amphibole asbestos (tremolite and actinolite), strongly suggests the need for detailed health-based studies in the region. The particulate samples show low to medium oxidative potential per unit of mass, in relation to an urban road side control, being more reactive with ascorbate than with glutathione or urate. However, the PM oxidative potential per volume of air is exceptionally high, confirming that the workers are exposed to a considerable oxidative environment. PM released by iron ore mining and processing activities should be considered a potential health risk to the mine workers and nearby employees, and strategies to combat the issue are suggested.
