1. AIR POLLUTION PRIMARY POLLUTANTS
ARE RELEASED VIA HUMAN ACTIVITY, EX. SOOT (SMALL PARTICULATES)FROM SMOKE

2. AIR POLLUTION SECONDARY POLLUTANTS ARE COMBINED PRIMARY POLLUTANTS
EX. GROUND LEVEL OZONE – COMBUSTION ENGINE EMISSIONS MIX WITH UVA RAYS FROM SUN.
100’S OF 1000’S OF TONS OF POLLUTANTS ENTER AIR EACH DAY.

3. AIR POLLUTION HISTORY OF AIR POLLUTION
POLLUTION REPORTED FROM ROME YEARS AGO.
BURNING OF SEA COAL (VERY SOFT) PROHIBITED IN 1300 C.E. BECAUSE OF
DIRTY AIR.

5. AIR POLLUTION CLEAN AIR ACT. LED TO ELIMINATION OF LEAD FROM GAS.
MOTOR VEHICLE EMISSIONS
1/3 OF ALL POLLUTION FROM BURNING
GASOLINE.
CONTROLLING VEHICLE EMISSIONS
EPA GIVEN POWER TO REGULATE
VEHICLE EMISSIONS IN 1970 VIA THE
CLEAN AIR ACT.
LED TO ELIMINATION OF LEAD FROM GAS.
LED TO USE OF CATALYTIC CONVERTERS TO CLEAN \
EXHAUST.

6. Primary Pollutants

7. AIR POLLUTION
SMOG
CREATED BY CHEMICAL REACTION WHEN MOTOR VEHICLE EMISSIONS, SUNLIGHT, AIR AND OZONE ARE COMBINED.
MAIN SOURCES: M.V. EMISSIONS AND INDUC

8. Smog

9. AIR POLLUTION REGULATING INDUSTRY EMISSIONS
CLEAN AIR ACT ALSO REQUIRES ELECTROSTATIC PRECIPITATOR’S USE. E.P.’S
EACH YEAR E.P.’S REMOVE 20 MILLION TONS OF ASH FROM COAL BURNING POWER PLANTS.

10. AIR POLLUTION CLEAN AIR ACT REQUIRES
INDUSTRY TO USE SCRUBBERS. WORK BY SPRAYING EMISSION GASES WITH WATER. WET, HEAVY SLUDGE FALLS AND IS REMOVED, CLEANER AIR IS RELEASED.

11. Regulating Air Pollution From Industry

12. TEMPERATURE INVERSIONS
What happens as you move up a mountain?
(as altitude increases)
It gets colder
What is an inversion
Flipped around
Since the air above is warmer than the air below the pollutants are trapped near the Earths surface
TEMPERATURE INVERSIONS CREATE DANGEROUS AIR POLLUTION CONDITIONS.
