NASA Data: Russia’s Norilsk and S. African Coal Town Kriel Top SO2 Emissions Hot Spots
Russia’s Norilsk smelter complex and a town in South Africa’s eastern coal mining province have the highest sulphur dioxide (SO2) emissions in the world, according to satellite data from U.S. space agency NASA. The NASA-compiled data published on Monday was commissioned by environmental group Greenpeace India and used the space authority’s satellites to track anthropogenic sulphur dioxide emission hot spots around the world. Scientists say that excessive exposure to SO2 particles causes long-term respiratory difficulties and stunted growth in infants among other problems. Norilsk, 300km (186 miles) inside the Arctic Circle, has the largest individual SO2 emissions, followed by the South African town of Kriel, about 150km east of Johannesburg, Monday’s report found. The industrial city of Norilsk is home to Norilsk Nickel, the world’s leading nickel and palladium producer. The company is implementing a massive program to improve the ecology of the city and its surroundings. The first stage of the program is complete. After the closure of an old nickel plant and reconstruction of nearby plants, emissions in the city’s residential area fell by 30%, Nornickel told Reuters on Monday. The second phase will involve a $2.5 billion sulphur project to help to reduce sulphur dioxide emissions in …
