Mining is the process of digging into the earth to extract naturally occurring minerals. It can be categorized as: surface mining, underground mining, and in situ mining. Surface mining is used to excavate ores at or close to the earth's surface ; underground and in situ mining both remove minerals from deeper deposits.
Nickel toxicity, specifically, was evaluated by researchers at Michigan State University who found it presented a multi-tiered toxic attack. First, nickel causes essential metal imbalances. It severely disrupts enzyme action and regulation. Finally, it causes and contributes to a high amount of oxidative stress.
