- Wis Efesus banget winates minangka logam beracun lan bisa nimbulaké cacat lair, kanker, etc.
- Meh 80% saka logam kadmium digunakake ing Nikel Baterei kadmium lan saiki lagi njupuk diganti karo isotop nikel.
- 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.
