The nickel deposits of Norilsk-Talnakh are the largest-known nickel-copper-palladium deposits in the world. The smelting of the nickel ore is directly responsible for severe pollution, which generally comes in the form of acid rain and smog. By some estimates, one percent of global sulfur dioxide (SO2) emissions come from Norilsk's nickel mines. The Nornickel company has its main operations in the area where it is the largest employer.
