"Pea soup", or a "pea souper", also known as a "black fog" or "killer fog", is a very thick and often yellowish, greenish, or blackish smog caused by air pollution that contains soot particulates and the poisonous gas sulfur dioxide. This very thick smog occurs in cities and is derived from the smoke given off by the burning of soft coal for home heating and in industrial processes. Smog of this intensity is often lethal to vulnerable people such as the elderly, the very young and those with respiratory problems. Pea soup fog was once prevalent in UK cities, especially London, where the coal smoke from millions of chimneys combined with the mists and fogs of the Thames valley. The result was commonly known as a "London particular" or "London fog", which then, in a reversal of the idiom, became the name for a thick pea and ham soup. King Edward I of England banned the burning of sea-coal by proclamation in London in 1272, after its smoke became a problem. By the 17th century London's pollution had become a serious problem, still due, in particular, to the burning of cheap, readily available sea coal. John Evelyn, advisor to King Charles II, defined the problem in his pamphlet, “” published in 1661, blaming coal, a “subterrany fuel” that had “a kind of virulent or arsenical vapour arising from it” for killing many. He proposed the relocation of industry out of the city and the planting of massive gardens of “odiferous flowers” to “tinge the air” and thus mask the pollution.
