Further, the radioactive waste from processing ...


Rare earth metals cause harm to humans by getting inside the body through the mouth, skin and respiratory tract and via injections. It is removed from the body through the body via bile discharge and urine. Those metals which remain in the body have harmful effects. Let us look at one such outbreak that happened in Indonesia due to tin mining.


Beginning in the 1990s, rare earth mining took off in this region, located in Southeast China about 300 miles north of Hong Kong. As China began to produce more smartphones, wind turbines, electric vehicles, and other high-tech products requiring rare earth elements, the mining intensified. But the removal of these elements from the earth's ...
