He said sulfur dioxide is mainly emitted by power plants in China, while nitrogen dioxide comes from power plants and vehicles, and ammonia comes from fertilizer use and vehicles. “The difference in China is that the haze starts from much smaller nanoparticles, and the sulfate formation process is only possible with ammonia to neutralize the particles,” Zhang said. After five days of living in a sulfurous hell, the Great Smog finally lifted on December 9, when a brisk wind from the west swept the toxic cloud away from London and out to the North Sea. The study said that similar conditions often occur in China. Our results showed that this process was facilitated by nitrogen dioxide, another co-product of coal burning, and occurred initially on natural fog.” “But how sulfur dioxide was turned into sulfuric acid was unclear. “People have known that sulfate was a big contributor to the fog, and sulfuric acid particles were formed from sulfur dioxide released by coal burning for residential use and power plants, and other means,” lead author Renyi Zhang, a scientist at Texas A&M University, said in a statement. Their work was published in Proceedings of the National Academy of Sciences. The incident eventually led to the Clean Air Act of 1956, restricting the burning of coal in urban areas in the United Kingdom.Ī team of scientists now believe they have solved the mystery of the exact cause and nature of the fog, through lab experiments and measuring the atmosphere in China, which is home to 16 of the 20 most polluted cities in the world. Between December 5 and 9, 1952, the environmental disaster strangled London. ) The terrible, choking fog had a nicknamethe Great Smog. 9, after cold winds swept the fumes out to the North Sea.
