The Russian city, Norilsk is one of the worst polluted areas in the world with 1% of the worlds sulphur dioxide emissions originating here. This is down to a number of reasons, some much more serious than others yet they have all contributed to the problems they face today. The city has an average population of about 175,000 people making it the second largest city north of the Arctic Circle. The area surrounding the city is a treeless tundra; this is where there is intense mining.
The mining is by the company MMC Norilsk nickel they will mine under the city for its nickel deposits supplying much of Russia’s nickel; this has led to the smelting of the nickel in a nearby factory which has caused much pollution with the usual occurrence of smog and acid rain. Recently the company has signed a protocol of cooperation with regard to environmental safety, just as Norilsk try to build a new better environment.
