6. USE TO BE IN GASOLINE AND HOUSE PAINT? AND IT CAUSES BRAIN/ORGAN DAMAGE?
LEAD
CAUSES PERMANENT LUNG DAMAGE- REACTS WITH WATER VAPOR TO PRODUCE ACID RAIN- ENTERS AIR FROM VEHICLE EXHAUST AND SOME POWER PLANTS-ALSO CAUSES OZONE FORMATION?

7. MATH AND AIR POLLUTION
This pie chart shows percentages of pollutants in the air.
Which 2 pollutants are the most common?

8. Percentages are given as part of 100
Percentages are given as part of 100. Usually, however, air pollution is measured in ppm or ppb. For example if PM makes up 36%, this can also be written as 36 pph, meaning for every 100 particles in the air, 36 of them are particulates. To convert this into ppm, set up the equation like this:
= X__
,000, solve for X
X= 360,000

9. The EPA first set air quality standards for CO in 1971
The EPA first set air quality standards for CO in For protection of both public health and welfare, EPA set a 1-hour primary standard at 35 ppm. How many parts per hundred is this?
= X
1,000,
X= 3.5 x10-3

10. For every gallon of gasoline that is burned, approximately 20 pounds of CO2 is released into the air. How many pounds of CO2 are produced if you burn 12 gallons of gas?
12 gallons lbs CO =
1 gallon
= 240 pounds CO2

11. If your car gets 25 miles per gallon and you drive to 300 miles to PCB, how many gallons do you burn?
How many pounds of CO2 are produced?

12. WHAT ARE THE 2 MAIN GASES IN THE ATMOSPHERE?
Nitrogen (78%) and oxygen (21%)

13. LIST 3 NATURAL SOURCES OF POLLUTION
Pollen
Volcanoes
Sea spray
dust

14. What car device changes harmful pollutants into less harmful ones?
CATALYTIC CONVERTER

15. NAME THE 2 BIG AIR POLLUTANT DISASTERS
DONORA, PA 1948
LONDON, ENGLAND 1952
WHAT WAS THE WEATHER CONDITION LIKE FOR BOTH OF THESE DISASTERS?
THERE WAS A THERMAL INVERSION
(BE ABLE TO DRAW ONE- REMEMBER, THE COLD AIR GETS TRAPPED BELOW WARMER AIR)

16. NAME 2 POLLUTANTS THAT CAN CREATE ACID RAIN
NOx and SO2

17. WHAT DOES THE WORD ANTHROPOGENIC MEAN?
MAN MADE
NAME 2 ANTHROPOGENIC CAUSES OF AIR POLLUTION
PRODUCING ENERGY AND DRIVING CARS

RESPIRATORY PROBLEMS
ASTHMA
DIFFICULTY BREATHING
COUGHING
ITCHY, IRRITATED EYES
EMPHYSEMA, LUNG CANCER
HEART ATTACKS AND STROKES

19. BURNING 1 GALLON OF GASOLINE PRODUCES ___ POUNDS OF CO220

20. LIST 6 GAS EMISSIONS FROM CARS
Water vapor
CO2 N2 CO
Nox
VOCs (hydrocarbons such as gasoline)

21. AN INVISIBLE,ODORLESS GAS THAT IS RADIOACTIVE
RADON

22. THIS INDOOR AIR POLLUTANT WAS USED IN INSULATION, BRAKE LINING AND RESIDENTIAL SIDING BECAUSE IT IS STRONG AND HEAT RESISTANT. BUT THE SILICA FIBERS CAN SCRATCH THE LUNGS
ASBESTOS

23. WHAT 2 POLLUTANTS CONTRIBUTE TO ACID RAIN?
SO2 and NOx

24. TRY THESE!
= X 2. Write 1/7 as a percent. 3. What does 75 ppm look like as a fraction? 4. Convert 2800 minutes into hours. 5. How many pounds of CO2 are released when 15 gallons of gas are burned? (1 gallon of gas produces 20 pounds of CO2 when burned)

25. ,200 = 700,000X X= 0.40
2. 1/7 x 100 = 14.3%
__75__ OR 7.5 x ,000,000
min hour = hours minutes
gallons lbs CO2__ = 300 pounds pound

26. Which is a stronger acid?
A pH of 4 or a pH of 6? 4
pH of 6 or pH of 12 6
