FIVE COMMON AIR POLLUTANTS

OZONE

OXIDES

Page 4: ENVIRONMENTAL HEALTH

OZONE

A gas composed of three oxygen atoms. SMOG- a yellowish-brown haze that forms when

sunlight reacts with air pollution

Page 5: ENVIRONMENTAL HEALTH

PARTICULATE MATTER

A general term for particles such as dust, dirt, soot, smoke, mold, or liquid droplets that are found in the air.

Page 6: ENVIRONMENTAL HEALTH

CARBON MONOXIDE

A colorless, odorless gas that contains carbon and oxygen.

Page 7: ENVIRONMENTAL HEALTH

SULFUR DIOXIDE

A gas made up of sulfur and oxygen. It dissolves in water to form an acid, and reacts with other gases in the air to form sulfates

Page 8: ENVIRONMENTAL HEALTH

NITROGEN OXIDES

A general term for a group of highly reactive gases that contain varying amounts of nitrogen and oxygen.

Page 9: ENVIRONMENTAL HEALTH

AIR QUALITY INDEX (AQI)

An index for reporting daily air quality

Page 10: ENVIRONMENTAL HEALTH

ASBESTOSA fibrous mineral that has fireproof properties

RADONAn odorless, radioactive gas

Page 11: ENVIRONMENTAL HEALTH

NOISE POLLUTION-A harmful and unwanted sound of sufficient intensity to damage hearing

DECIBEL-A unit used to express the relative intensity of loudness of sound

DECIBEL LEVELS OF COMMON SOUNDS

Page 16: ENVIRONMENTAL HEALTH

BIODEGRADABLE

Able to be broken down by microorganisms in the environment

LANDFILL

An area that has been safeguarded to prevent disposed wastes from contaminating groundwater

Page 17: ENVIRONMENTAL HEALTH
Page 18: ENVIRONMENTAL HEALTH

HAZARDOUS WASTE

A substance that is explosive, corrosive, highly reactive, or toxic to humans or other life forms

Page 19: ENVIRONMENTAL HEALTH
Page 20: ENVIRONMENTAL HEALTH

DEFORESTATION

Destruction of forests

Page 21: ENVIRONMENTAL HEALTH
Page 22: ENVIRONMENTAL HEALTH

URBAN SPRAWL

The spreading of city development onto undeveloped land

Page 23: ENVIRONMENTAL HEALTH
Page 24: ENVIRONMENTAL HEALTH

WASTEWATER

Used water that comes from homes, communities, farms, and businesses

Page 25: ENVIRONMENTAL HEALTH
Page 26: ENVIRONMENTAL HEALTH

OTHER SOURCES OF WATER POLLUTION

SEDIMENTFrom land erosion can destroy aquatic ecosystems and clog lakes, streams, channels, and harbors

OILSome comes from the cleaning of oil tankers and from offshore drilling sites. Problems are also from when people dump motor oil or household chemicals down storm drains

WHAT CAN YOU DO TO HELP?? 1- Recycle

2- Dispose of all materials properly

3- Follow directions when using chemicals such as cleaning products and pesticides

4- Reduce water usage

Page 30: ENVIRONMENTAL HEALTH

CONSERVATION

The protection and preservation of the environment by managing natural resources to prevent abuse, destruction, and neglect

Page 31: ENVIRONMENTAL HEALTH

HEATING AND COOLING

Seal leaks around doors, windows, and electrical sockets to prevent heated and cooled air from escaping

During heating season, wear an extra layer of clothing instead of turning up the thermostat. (68 degrees)

Keep thermostat at 78 degrees during air-conditioning season

Page 32: ENVIRONMENTAL HEALTH

WATER CONSERVATION

Wash clothes in warm or cold water. Accumulate a full load before washing laundry or running the dishwasher.

Fix leaky faucets, and never let the water run unnecessarily. Turning off the water while brushing your teeth or shave can save 4.5 gallons of water per minute.

Page 33: ENVIRONMENTAL HEALTH

LIGHTING AND APPLIANCES

Replace traditional lightbulbs with fluorescent bulbs.

Switch off lights when you leave a room Turn off tv’s, radios, computers, and other

appliances when not in use Use a microwave or toaster oven instead of a

conventional oven when cooking a small amount of food

Don’t preheat oven for longer than necessary. Avoid opening the oven door unnecessarily while the appliance is in use.

PRECYCLING-Reducing waste before it is generated- (purchasing and using products wisely)

RECYCLING-The processing of waste materials so that they can be used again

Page 35: ENVIRONMENTAL HEALTH

RECYCLING BENEFITS:

1- Recycling conserves resources

2- Recycling reduces reliance on landfills

3- Recycling protects environmental health

Page 36: ENVIRONMENTAL HEALTH

TIPS FOR RECYCLING AND REDUCING WASTES Aluminum-

Rinse aluminum and crush cans

Cardboard- Flatten cardboard

Glass- Rinse

Plastics- Look for code on container. Most recyclers take those

marked 1, 2, or 3.

Newspapers- Stack newspapers and tie in bundles

Glossy paper- Contact services that help you remove your name from

mailing lists

Page 37: ENVIRONMENTAL HEALTH

PROTECTING THE ENVIRONMENT

Become an informed consumer

Contact organizations that promote the conservation or resources and educate people on environmental issues

Take action against local polluters
