Airborne copper is associated with particulates that are obtained from suspended soils, combustion sources, the manufacture or processing of copper-containing materials, or mine tailings. The median concentration of copper in natural water (e.g., rivers, lakes, and oceans) is 4–10 ppb. It is predominantly in the Cu(II) state.

Extracting these natural resources is frequently a destructive activity that damages the rainforest ecosystem and causes problems for people living nearby and downstream from mining operations.
أكمل القراءةAlthough mining is a cornerstone of the South African economy (), it generates copious amounts of dust. 1 The dusts may be toxic since they may also be contaminated with various toxic metals.For this reason, the prevalence and severity of occupational diseases in the mining industry depends on the ores mined, the contaminants present and also on the levels and duration of exposure …
أكمل القراءةMining is always going to be more dangerous than office work. But this inherent danger, and the relentless drumbeat of death, induces a fatalism, and is an obstacle to attempts to make mining safer. Miners are expected to accept that dying at work is part of the job. And those who do make it to the surface face a host of diseases and injuries.

أكمل القراءةJournal of Heavy Metal Toxicity and Diseases is an open access Journal and publishes the articles after thorough peer review.. Heavy Metal Toxicity refers to an overexposure to lead, mercury, arsenic, cadmium, chromium or other high density or metallic element that causes irritation or damage to the body. Heavy metals can be found naturally in the environment, in homes, or at the work place.
أكمل القراءةGenetic disorders associated with metal metabolism form a large group of disorders and mostly result from defects in the proteins/enzymes involved in nutrient metabolism and energy production. These defects can affect different metabolic pathways and cause mild to severe disorders related to metal metabolism. Some disorders have moderate to severe clinical consequences.
أكمل القراءةCopper-nickel mining (also known as "non-ferrous mining") in northern Minnesota is not a new issue for the state. Copper-nickel deposits have been known to exist in northern Minnesota since the 1800s, but it was not until 1948, when deposits were discovered near Duluth, that serious interest in mining these metals developed in the region.
أكمل القراءةConclusion of the Mortality Study. In our study, exposure to dust was not associated with an increase in lung cancer. However, we found an increase in auto-immune diseases, other lung diseases including silicosis and tuberculosis.

أكمل القراءةMining 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. I look at mining and health from various personal perspectives: that of the ordinary man ...
أكمل القراءةCopper toxicity (or Copperiedus) is a type of metal poisoning caused by an excess of copper in the body. Copperiedus can occur from eating acidic foods cooked in uncoated copper cookware, an IUD, or from exposure to excess copper in drinking water and other environmental sources, or the genetic condition Wilson's disease .
أكمل القراءةWilson's disease (WD) is a rare autosomal recessive disorder of hepatocellular copper deposition. The diagnostic approach to patients with WD may be challenging and is based on a complex set of clinical findings that derive from patient history, physical examination, as well as laboratory and imaging testing. No single examination can unequivocally confirm or exclude the disease.
أكمل القراءةHeavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological applications have led to their wide distribution in the environment; raising concerns over their potential effects on human health and the environment.

أكمل القراءةMining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes. The leakage of chemicals from mining sites can also have detrimental effects on the health of the population living at or around the mining site.
أكمل القراءةIn 1939, the German physician, Werner Hangarter, noticed that Finnish copper miners were unaffected by arthritis as long as they worked in the mining industry. This was particularly striking since rheumatism was a widespread disease in Finland, and workers in other industries and other towns had more rheumatic diseases than did the copper miners.
