- Sampeyan uga dipigunakaké ing insecticides, alami rambute lan minangka aditif anti-nuthuk kanggo bensin. Nanging kabeh iki dilarang déning pamaréntah minangka logam Lead dikenal kanggo ngrugekake kanggo kesehatan.
- Wis cenderung kanggo njaluk tarnished ing online mbukak, nanging nalika alloyed karo unsur kaya erbium, vanadium, tingkat atose sudo.
- senyawa kaya Erbium oxide digunakake ing kaca tingal safety saka welders lan buruh metal.
