This document discusses various sources and effects of air pollution. It identifies transportation, factories, and forest fires as common sources that emit pollutants like carbon monoxide, sulfur dioxide, nitrogen dioxide, particulate matter, and ground-level ozone. These pollutants can damage human health by causing issues like headaches, respiratory problems, and reduced lung function. The document also mentions that air pollution contributes to issues like acid rain, global warming, and the thinning of the ozone layer, which affect both the environment and human life. It encourages actions like using renewable energy, reducing waste, recycling, and promoting plant growth to help address the problems caused by air pollution.
2. Air pollution harms human
health and the environment.
Transportation, Factories, Forest fires
Are common sources of air pollution
4. Carbon Monoxide •present in car exhaust
•colorless, odorless •deprives body of O2 causing
•produced when carbon does headaches, fatigue, and impaired vision
not burn in fossil fuels
5. Sulfur Dioxide
•produced when coal and fuel oil
•narrows the airway,
are burned
Causing wheezing and
•present in power plant exhaust
Shortness of breath,
especially
in those with asthma
6. Nitrogen Dioxide
•present in car exhaust and
power plants
•affects lungs and causes
•reddish, brown gas wheezing; increases chance
of respiratory infection
•produced when nitric
oxide combines with
oxygen in the
atmosphere
7. Particulate Matter
•can build up in
•particles of
respiratory
different sizes system
and structures
that are released •aggravates
heart and lung
into the
disease;
atmosphere increases risk
of respiratory
•present in many
infection
sources including
fossil fuels,
dust, smoke, fog,
etc.
8. Ground Level Ozone
•at upper level, ozone shields
Earth from sun’s harmful uv rays
•at ground
level, ozone is
harmful pollutants
• formed from
• car, power
• and
• Chemical
plant exhaust
•irritate respiratory system and
asthma; reduces lung function by
inflaming and damaging lining of
lungs
9. Global Warming Greenhouse Effect
Thinning of Upper
Acid Rain Ozone Layer
