  1. Human impact Storage areas Sulfur Cycle Britt Gumerman & Olivia Kolditz Sulfur reactions Inoranic and organic Pathway of movement

  2. Impact of Human Intervention Refining sulfur-containing petroleum to make gasoline, heating oil, and other useful products. Burning sulfur-containing coal and oil to produce electric power. Using smelting to convert sulfur compounds of metallic minerals into free metals such as copper, lead, and zinc Since the Industrial Revolution, human activities have contributed to the amount of sulfur that enters the atmosphere. Result of acid rain The sulfur released by humans such as sulfur dioxides and sulfur aerosols also results in acid rain

  3. Sulfur Reactions Reaction to sulfur with air Sulfur burns in air to form the gaseous dioxide sulfur(IV) oxide, SO2. S8(s) + 8O2(g) → 8SO2(g) Reaction of sulfur with water Sulfur does not react with water under normal conditions. Reaction of sulfur with the halogens Sulfur reacts with all the halogens upon heating. Sulfur reacts with fluorine, F2, and burns to form the hexafluoride sulfur(VI) fluoride. S8(s) + 24F2(g) → 8SF6(l) [orange] Reaction of sulfur with acids Sulfur does not react with dilute non-oxidizing acids. Reaction of sulfur with bases Sulfur reacts with hot aqueous potassium hydroxide, KOH, to form sulfide and thiosulphate species. S8(s) + 6KOH(as) → 2K2S3 + K2S2O3 + 3H2O(l)

  4. Pathway of Movement

  5. Two Largest Storage Areas For Sulfur • Terrestrial rocks • Ocean sediments Terrestrial rock Ocean sediments

  6. Inorganic Organic • Sodium dithionite, Na2S2O4 • Thiosulfates (S2O32−) • Sulfides (S2−) • Sulfites (SO32−) • Sulfates (SO42−) • Thioethers • Sulfonium • Thiols • Thiolates • Sulfoxides • Sulfones Located in acid deposits Located in Earth’s crust
