Sulfur

Sulfate salts

Dimethyl sulfide

• (CH3)2S

• Emissions from Phytoplankton• Occurs over oceans

Sulfur dioxide

• SO2

• Emissions:• Industries example : power plants• Volcanoes

Sulfur Trioxide

• SO3

• Primary agent in acid rain

Sulfuric acid

• H2SO4

• Principal uses include: ore processing• fertilizer processing • Oil refining

Ammonium Sulfate

• (NH4)2SO4

• Made when ammonia reacts with H2SO4

• Uses:• Fertilizer• Agricultural spray- aids for water soluble pesticides

Hydrogen Sulfide

• H2S

• Emitted by volcanoes and hot springs• Remains in atmosphere for 18 hours• Changes into sulfur dioxide
