The composition of heavy metals (and metalloid) in surface soils of iron ore mine-impacted areas has been evaluated of their potential ecological and human health risks. The …
Introduction. Aluminum, the most abundant metallic element in the earth's crust, is a light metal with excellent heat and electrical conductivity (Keith et al. 2008).By mass, 8.8% (88 g/kg) of the earth's crust is aluminum, and it can be found in numerous amounts of rocks (Keith et al. 2008).By the natural weathering of rocks, aluminum is …
Non-animal models of epithelial barriers (skin, intestinal and pulmonary context) play a critical role for in vitro to in vivo extrapolation. Immortalised human adenocarcinoma cell lines (such as Caco-2 or T84) help to study absorption mechanisms, as do immortalised cell lines (e.g. …
Different lung diseases including lung cancer are the major occupational diseases among the workers of iron ore dust. However, health hazards that arise due to exposures to the …
Soils contaminated with heavy metals may pose very dangerous effects to human health and the environment. Contaminants impairing the soils from iron ore …
Objective: Coal mining activities have continuously introduced heavy metals into the soil-crop system, causing increasing damage to crops. This study integrated the analysis of the heavy metal contamination status and human health risk in soil and maize near coal mines to help formulate control strategies for soil quality, maize production, …
6. Thermal stress. A common health risk that miners face is thermal – or heat – stress. "Mining environments are often very hot and humid, particularly those in outback Australia, which over time can cause thermal stress in workers. "Overexposure to heat and humidity can cause the body to become fatigued and distressed.
The four mines are spread over nearly 2,000 hectares and located in the Karauli district. The state mines department has already auctioned four major mineral blocks, so far, this financial year ...
Canada exported 55.1 million tonnes of iron ore valued at $8.8 billion in 2022 compared to 53.9 million tonnes valued at $10.1 billion in 2021. Higher export volume but lower export value reflects lower prices in 2022. Iron ore pellets accounted for 27% of the volume, whereas other concentrates (non-agglomerated) accounted for the …
The principal airborne hazards in the mining industry include several types of particulates, naturally occurring gases, engine exhaust and some chemical vapours; the principal physical hazards are noise, segmental vibration, heat, changes in barometric pressure and ionizing radiation. These occur in varying combinations depending on the …
Environmental and social research studies have debated the impact of acid mine drainage (AMD). Solutions to the problems caused by AMD have tended towards a technocratic investment in temporary to long-term solutions. However, the health effects of AMD remain neglected in research and policy arenas because of the lack of …
Many of the findings related to occupational exposures and adverse health outcomes presented in this chapter are based on studies of uranium and hard-rock miners (e.g., worker-based radon studies) for periods of disease risk when the magnitude of the exposures was much greater than the exposures reported at most mines and …
Contamination and pollution of soil and water. Large quantities of water can become contaminated with environmentally harmful tailings being stored in dams, which can present a severe risk in case of dam failure. Dust and particulate matter released during mining can have adverse effects on the respiratory systems of nearby humans and animals.
Similarly, the MSHA documented 11,800 work-related injuries among American miners from 2006 to 2007 (the most recent year for which statistics are available), down from the 27,524 work-related ...
In 2018, Australia's EDR of iron ore increased by 3% from 2017 to 49 604 Mt (Table 3). Similarly, there was a 4% EDR increase of contained iron to 24 122 Mt (Table 4). EDR attributable to magnetite deposits have decreased by 1%, likely due to re-assessment of projects and inactivity in the magnetite industry.
Contamination of surface and groundwater resources to heavy metal due to mining activities is a worldwide major issue because of its probable health risks to local residents. In the present research, we measured the concentrations of As, Cd and Cr in 26 water samples collected from 13 rural areas in the vicinity of mines in Sabzevar, Iran ...
The composition of heavy metals (and metalloid) in surface soils of iron ore mine-impacted areas has been evaluated of their potential ecological and human health risks. The mining areas...
There remains a paucity of data about the respiratory health effects from exposure to iron ore dust generated by mining. The aim of this novel study was to …
Metal contamination from base metal sulphide mines is a major environmental challenge that poses many ecological and health risks. We examined the metal concentrations in the Dabaoshan mine in South China in water, sediments, and aquatic organisms and their specific characteristics (i.e. size, body tissue, species, and habitat) along the Hengshi …
Characteristics of mining spoiled and oil drilling sites and adverse impacts of these activities on the environment and human health. Lala Saha, Kuldeep Bauddh, in Phytorestoration of Abandoned Mining and Oil Drilling Sites, 2021. 4.2.4 Iron ore mining. Iron ore is another important mineral from which metallic iron is extracted. The high …
Jun 2, 2023. Workplace hazards pose significant risks to the health and safety of employees. In industries like mining, these risks can be even greater due to the nature of work being carried out. Workers in mines are exposed to a variety of potential hazards such as explosions, cave-ins, gas leaks, and machinery accidents.
Large quantities of water can become contaminated with environmentally harmful tailings being stored in dams, which can present a severe risk in case of dam failure. Dust and …
Abstract. There are an estimated 5 million children working in artisanal and small-scale gold mines worldwide; however, the hazards are poorly characterized and often underreported. We systematically reviewed the literature on reports of hazards among children as a consequence of such activities through PubMed database using pre …
A Welsh Affairs Committee inquiry into the potential human health risks of pollution from abandoned metal mines in Wales takes place on Wednesday. The north of Ceredigion is home to more than 400 ...
Crispin Pierce, a UW-Eau Claire associate professor of nursing, found that frac sand mining facilities add significant particulate matter pollution to the air. The dangerous particles are microscopic, measuring PM (particulate matter) 2.5 or smaller. As a reference, one strand of human hair is approximately PM 70.
Baffinland Iron Mines Corporation (Baffinland) is a Canadian mining company, mining iron ore at the Mary River operation in the Qikiqtani region of North Baffin, Nunavut, Canada. It is jointly owned by The Energy and Minerals Group and ArcelorMittal and operates a high-grade iron ore mine here. Our mine produces the highest grade of direct ...
Abstract. Mining continues to be a dangerous activity, whether large-scale industrial mining or small-scale artisanal mining. Not only are there accidents, but exposure to dust and toxins, along with stress from the working environment or managerial pressures, give rise to a range of diseases that affect miners.
The Kolomela Mine is situated near Postmasburg Town in the Northern Cape Territory in South Africa. Mining operation at Kolomela started in late 2011. A stacker-reclaimer is used at Kolomela to blend different grades of processed ore before shipment. Kolomela produced 13.2Mt of direct shipping iron ore in 2019.
