Sulfur fumarole: As hot volcanic gases, rich in sulfur, escape from a volcanic vent, the gases cool and sulfur is deposited as yellow crystals around the vent. This fumarole on the island of Kunashir in the Kuril Islands, northeast of the Japanese island of Hokkaido has a significant accumulation of bright yellow sulfur.
Sulfur is a chemical element with an atomic number of 16 and an atomic symbol of S. At room temperature it is a yellow crystalline solid. Even though it is insoluble in water, it is one of the most versatile elements at forming compounds. Sulfur reacts and forms compounds with all elements except gold , iodine, iridium, nitrogen, platinum, tellurium, and the inert gases.
Sulfur is abundant and occurs throughout the Universe, but it is rarely found in a pure, uncombined form at Earth's surface. As an element, sulfur is an important constituent of sulfate and sulfide minerals. It occurs in the dissolved ions of many waters. It is an important constituent of many atmospheric, subsurface, and dissolved gases. It is an essential element in all living things and is in the organic molecules of all fossil fuels. World Sulfur Production: During , an estimated 70 million metric tons of sulfur was produced worldwide.
The production was widely divided among a large number of countries. These countries are where the sulfur was separated from its geologic source material rather than the original source of the sulfur, since most sulfur is separated when fossil fuels are processed or sulfide ores are smelted.
Data from the United States Geological Survey. The information below should convince you that sulfur is extremely abundant and present everywhere. Rotten eggs and stink bombs get their distinctive aroma because of hydrogen sulfide. Few elements are high profile enough to get a mention in the Bible, much less 15 separate call-outs. But sulfur occurs frequently in compounds in nature, usually as a stinky, yellow mineral associated with hot springs and volcanoes, perhaps explaining why the authors of the Bible associated it with hellfire and wrath.
Gay-Lussac was known for his research on gases, which involved him flying in hydrogen-filled balloons more than 22, feet 7, meters above sea level, according to the Chemical Heritage Foundation. When burned, sulfur produces a blue flame and sulfur dioxide gas — a common pollutant, according to the Environmental Protection Agency. Sulfur dioxide in the atmosphere comes mostly from fossil-fuel power plants and is one of the primary causes of acid rain. The gas is also a lung irritant. The EPA regulates sulfur dioxide emissions along with five other so-called "criteria pollutants," including lead and carbon monoxide.
Today, sulfur is a byproduct of the refinement of fossil fuels into usable energy sources like gasoline. This refinement is a good thing for preventing sulfur compounds from heading skyward when the fuel is burned, causing acid rain. But it leads to hills of elemental sulfur piling up in refineries.
About 90 percent of this elemental sulfur goes to make sulfuric acid, said Jeff Pyun, a biochemist at the University of Arizona. But "since we go through millions of barrels of oil a day, a few percent [sulfur] a barrel just piles up quickly," Pyun said. With nearly million tons of waste sulfur produced a year, the 10 percent not used in sulfuric acid production comes out to a not-insignificant 10 million tons a year. Hydrogen sulfide H 2 S is a gas that smells like rotten eggs.
Sulfur dioxide SO 2 , formed by burning sulfur in air, is used as a bleaching agent, solvent, disinfectant and as a refrigerant. When combined with water H 2 O , sulfur dioxide forms sulfurous acid H 2 SO 3 , a weak acid that is a major component of acid rain.

Breathing in sulfur dust can irritate the airways or cause coughing. It can also be irritating to the skin and eyes. Blurred vision has also been reported. If animals eat too much sulfur, it may be toxic and can be fatal.
Signs of poisoning in animals include problems to the stomach and intestines, effects on the lungs, and neurologic disorders. Signs associated with brain damage can include blindness, incoordination, seizures, death, and others. Burning sulfur creates sulfur dioxide, a gas. If inhaled, coughing, shortness of breath, sore throat, and labored breathing, has been reported. Eye irritation has also been reported. Sulfur is essential for humans, animals, and plants.
When it enters our body it can be incorporated into tissues like skin and cartilage. It is also found in some proteins and vitamins. When sulfur gets on intact skin, most of it does not get into the bloodstream. However, it can be absorbed into skin itself. In one study, sulfur was applied to the skin and was detectable from 2 to 8 hours afterwards. It was undetectable after 24 hours. In another study, sulfur was applied for 8 hours to the skin of four volunteers.
Sulfur was found in urine 2 hours later and after 6 hours it reached its maximum.
