ACID DEPOSTION a.k.a. Acid rain

What is acid deposition? pH less than 7 Wet Rain Snow

COLA

What happens when you mix pH? Acid + Base= neutral Add bases (antacid) to acids to neutralize! BASES ARE GOOD FOR ACID RAIN NEUTRALIZATION!!!

Acid rain in Europe

ACID RAIN IS MANY ACIDS Sulfuric acid Nitric acid Carbonic acid

Sulfuric acid Source Coal burning power plants (electricity) industry

Nox Sources- Gasoline burning industry

Carbonic acid Natural From volcanoes, respiration Burning of fossil fuels Acid used in most cave formation Limestone + carbonic acid = calcium bicarbonate (soluable)

EFFECTS OF ACID RAIN

Wears away rock and metal

Harms aquatic life

KILLS PLANTS Especially conifers Black Forest (Germany)

Does acid rain hurt people? Indirectly Breath in harmful particulates that damage lung tissue

SOLUTIONS? Smokestack scrubbers on coal burning plants

Solutions Wash coal (less sulfur)

Solutions Catalytic converters on cars (filter Nox)

Solutions Alternative energy sources (less fossil fuels)
