Acidic fog and precipitation Ammonium sulfate Ammonia Sulfuric acid Water Sulfur trioxide Oxygen Hydrogen sulfide Sulfur dioxide Volcano Industries Dimethyl sulfide Ocean Metallic sulfide deposits Decaying matter Animals Plants Hydrogen sulfide Sulfur Sulfate salts

Dimethyl sulfide (CH 3 ) 2 S Emissions from Phytoplankton Occurs over oceans

Sulfur dioxide SO 2 Emissions: Industries example : power plants Volcanoes

Sulfur Trioxide SO 3 Primary agent in acid rain

Sulfuric acid H 2 SO 4 Principal uses include: ore processing fertilizer processing Oil refining

Ammonium Sulfate (NH 4 ) 2 SO 4 Made when ammonia reacts with H 2 SO 4 Uses: Fertilizer Agricultural spray - aids for water soluble pesticides

Hydrogen Sulfide H 2 S Emitted by volcanoes and hot springs Remains in atmosphere for 18 hours Changes into sulfur dioxide

Acidic fog and precipitation Ammonium sulfate Ammonia Sulfuric acid Water Sulfur trioxide Oxygen Hydrogen sulfide Sulfur dioxide Volcano Industries Dimethyl sulfide Ocean Metallic sulfide deposits Decaying matter Animals Plants Hydrogen sulfide Sulfur Sulfate salts

Importance Nutrient for organisms Bacteria oxidize sulfur for energy Factor for plant productivity
