NAME THE 6 CRITERIA AIR POLLUTANTS

• CARBON MONOXIDE• NITROGEN OXIDES• LEAD• OZONE• PARTICULATE MATTER• SULFATES

WHICH POLLUTANT…

• IS PRODUCED FROM SOURCES SUCH AS BURNING COAL, NATURAL GAS, KEROSENE, WOOD BURNING STOVES?

• CARBON MONOXIDE• COMES FROM POWER PLANTS, DUST, WOOD

BURNING STOVES AND FIRES?• PARTICULATE MATTER

• FORMS FROM THE INTERACTION OF SUNLIGHT WITH HYDROCARBONS? (EVAPORATED FROM FUEL THAT DID NOT BURN COMPLETELY)

• OZONE• A COLORLESS, ODORLESS GAS WHOSE MAIN

SOURCE IS MOTOR VEHICLES?• CARBON MONOXIDE

LIST SOME EFFECTS OF ACID RAIN ON THE ENVIRONMENT

damage to tree health damage to soil fish killsdecreases crop yieldsdestroys statues and monuments

• 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?

• NOX

MATH AND AIR POLLUTION

• This pie chart shows percentages of pollutants in the air.

• Which 2 pollutants are the most common?

• 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:

• 36 = X__ 100 1,000,000 solve for XX= 360,000

• The EPA first set air quality standards for CO in 1971. 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?

• 35 = X 1,000,000 100• X= 3.5 x10-3

• 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 20 lbs CO2 = 1 gallon = 240 pounds CO2

• 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?

WHAT ARE THE 2 MAIN GASES IN THE ATMOSPHERE?

• Nitrogen (78%) and oxygen (21%)

LIST 3 NATURAL SOURCES OF POLLUTION

• Pollen• Volcanoes• Sea spray• dust

What car device changes harmful pollutants into less harmful ones?

• CATALYTIC CONVERTER

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)

NAME 2 POLLUTANTS THAT CAN CREATE ACID RAIN

• NOx and SO2

WHAT DOES THE WORD ANTHROPOGENIC MEAN?

• MAN MADE• NAME 2 ANTHROPOGENIC CAUSES OF AIR

POLLUTION• PRODUCING ENERGY AND DRIVING CARS

GIVE EXAMPLES OF HEALTH PROBLEMS RELATED TO AIR POLLUTION

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

• BURNING 1 GALLON OF GASOLINE PRODUCES ___ POUNDS OF CO2

• 20

LIST 6 GAS EMISSIONS FROM CARS

• Water vapor• CO2• N2• CO• Nox• VOCs (hydrocarbons such as gasoline)

AN INVISIBLE,ODORLESS GAS THAT IS RADIOACTIVE

• RADON

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

WHAT 2 POLLUTANTS CONTRIBUTE TO ACID RAIN?

• SO2 and NOx

TRY THESE!1. 700 = 354 800 1000X2. 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)

• 1. 283,200 = 700,000X X= 0.40• 2. 1/7 x 100 = 14.3%• 3. __75__ 0.000075 OR 7.5 x 10-5

1,000,000 • 4. 2800 min 1 hour = 46.7 hours

1 pound

Which is a stronger acid?

• A pH of 4 or a pH of 6?• 4• pH of 6 or pH of 12• 6

• An acid with a pH of 2 is ___ times stronger than one with a pH of 3.

• 10• An acid with a pH of 2 is ___ times stronger than

one with a pH 4• 100• An acid with a pH of 2 is ___ times stronger than

one with a pH of 5• 1000

Identify as either an acid or a base

• Tomatoes• ACID• Vinegar• ACID• Soap• BASE

• soda• ACID• Bleach• BASE• Lemon juice• ACID
