Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silie minerals, known as sheet silies because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heatresistant and does not conduct electricity.

Longterm exposure to copper can cause irritation of the nose, mouth and eyes and it causes headaches, stomachaches, dizziness, vomiting and diarrhea.
The environmental impact of fracking for natural gas. Natural gas is a relatively cleanburning fuel source — it produces approximately half the CO 2 emissions that coal burning produces — so demand for natural gas has increased in the last few decades as
Cumulative and Associated Environmental Impacts The most obvious environmental impact from aggregate, stone, and industrial mineral mines is degraded air quality, and associated health effects, resulting from airborne emissions from both the stack and the disturbed areas at these mines. In an arid landscape like New Mexico, the
The use of mercury in gold mining is causing a global health and environmental crisis. Mercury, a liquid metal, is used in artisanal and smallscale gold mining to extract gold from rock and sediment. Unfortunately, mercury is a toxic substance that wreaks havoc on miners'' health, not to mention the health of the planet.
