Therefore, micas play a role in restricting the contamination of 137 Cs + to the terrestrial food chain and the impact on human health. Structural Fe contents of micas may be substantial. For example, Fe accounts for approximately 23% by mass of ideal biotite. Structural Fe can participate in electron-transfer reactions in soils.
The diagnosis of mica pneumoconiosis is complex due to its diverse pathophysiological characteristics, many of which mimic those caused by conventional exposures. Moreover, mica pneumoconiosis can have a very long latency period (sometimes as long as 40 years), and disease progression can continue even after …

Answer (1 of 3): The mining lead to further deforestation as large stretches of forests in the area are illegally cleared. Illegal mining served the dual purpose by extracting mica and providing timber. Trees are cleared routinely to bring new land under mica mining.
In either case, it is a very economically risky mining procedure because of the cost involved in locating the vein and the unpredictability of the quality and quantity of the mica that might be recovered once the vein is located and worked.
A possible association of MICA polymorphism with genetic predisposition to different cancer types has been investigated in candidate gene-based studies. Two genome-wide association studies have identified loci in MICA that influence susceptibility to cervical …

Pancreatic cancer risk is increased by 82% in those with diabetes vs those without 35, and several studies have reported evidence that MICA gene polymorphisms are linked to diabetes 47 –50. In addition, diabetes is often diagnosed at the time or after pancreatic cancer diagnosis and may be a consequence of pancreatic cancer rather …

It is estimated that 25% of the world production of mica is sourced from these illegal mines. According to Terre des Hommes (TDH) Netherlands: The work is exhausting, hazardous and jeopardising their health. Moreover, those children cannot attend school and will therefore be trapped in a vicious cycle of exploitation.
Of 34 studies identified, 27 studied coal mining as an occupational exposure (coal miner cohort or as a retrospective risk factor) but only seven explored health effects in surrounding populations. Overall, risk assessments were reported for 20 cancer site categories, but their results and frequency varied considerably.
To tell the truth, the majority of the Mica is linked to child labour and illegal mines in the rural states of India where there is lesser growth, democracy, and development. People in Jharkhand, Ampikazo, Madagascar are trapped in a cycle of poverty where putting food on the table is a problem to many.
The mining also leads to further deforestation as large stretches of forests in the area are illegally cleared. "Illegal mining serves the dual purpose by extracting mica and providing timber. Trees are cleared routinely to bring new land …
