If workers mining talc and manufacturing products made with talc were experiencing the negative effects of asbestos exposure, it stood to reason consumers were also being exposed. Testing revealed that two cosmetic talc products from two unidentified brands were found to contain asbestos.
Dec 08, 2018 Mining involves the extraction of valuable minerals from the earth surface. Mining can either be surface mining or sub-surface (underground) mining. Mining not only beneficial to the surrounding community and public in general, but it can also pose a lot of risks to the surrounding community. Lets look at the pros and cons of mining
Talc is a white powder that absorbs moisture and softens the skin. It also adds texture to products and, by absorbing liquids, creates an inhospitable environment to micro-organisms which helps make self-preserving products. Talc is hydrated magnesium silicate, a naturally occurring mineral that is extracted from the ground, milled into a powder and purified.

Jun 05, 2018 Positive Effects of Mining. Economic Growth. Mining is a vital driver role of economic growth in numerous countries. Locally, it provides much-needed jobs and investment capital. At the top level, it can drive and define national growth. Some nations depend solely on extracting natural resources like many found in the Middle East.
Dec 13, 2000 Talc containing asbestiform fibers is known to be a human carcinogen based on sufficient evidence of carcinogenicity from human epidemiological studies. This evidence indicates a moderate increase in lung cancer mortality among workers exposed to talc dust in talc mining and milling operations and in other industrial settings where talc is used.

Objective To evaluate late respiratory effects from occupational inhalation of talc contaminated with asbestos. Methods This was a case series study on 29 former talc mining workers with asbestos contamination, in the municipality of Caranda, Southeastern Brazil, who were attended at the State Workers Health Reference Center in 2004 and 2005.
Several published meta-analyses consistently reported a small but positive association with ovarian cancer and perineal talc use. The draft screening assessment did not identify any critical health effects for talc through oral exposure, for example, talc in drugs, or dermal (non-perineal) routes of exposure.
What Are the Benefits of Mining? Despite the ecological harm that mining inflicts we continue to extract substances from the ground because we feel as a society that the benefits of mining outweigh the hurts, especially as we develop new ways to counteract the negative impact of mining on the environment.
