DESCRIPTION
environment- air pollution
Citation preview
Any visible or invisible particle or gas found in the air that is not part of the original, normal composition.
Natural: forest fires, pollen, dust storm
Unnatural: man-made; coal, wood and other fuels used in cars, homes, and factories for energy
AQI: Air Quality IndexIndicates whether pollutant levels in air may cause health concerns.Ranges from 0 (least concern) to 500 (greatest concern)
Air QualityAir Quality IndexProtect Your HealthGood0-50No health impacts are expected when air quality is in this range. Moderate51-100Unusually sensitive people should consider limiting prolonged outdoor exertion.Unhealthy for Sensitive Groups101-150Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.Unhealthy151-200Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion, everyone else, especially children should limit prolonged outdoor excertion.

5 Major Pollutants:1..) Carbon Monoxide2.) Sulfur Dioxide3.) Nitrogen Dioxide4.) Particulate Matter5.) Ground Level Ozone
Carbon Monoxidecolorless, odorlessproduced when carbon does not burn in fossil fuelspresent in car exhaustdeprives body of O2 causing headaches, fatigue, and impaired vision
Sulfur Dioxideproduced when coal and fuel oil are burnedpresent in power plant exhaustnarrows the airway, causing wheezing and shortness of breath, especially in those with asthma
Nitrogen Dioxidereddish, brown gasproduced when nitric oxide combines with oxygen in the atmospherepresent in car exhaust and power plantsaffects lungs and causes wheezing; increases chance of respiratory infection
Particulate Matterparticles of different sizes and structures that are released into the atmospherepresent in many sources including fossil fuels, dust, smoke, fog, etc.can build up in respiratory systemaggravates heart and lung disease; increases risk of respiratory infection
Ground Level Ozoneat upper level, ozone shields Earth from suns harmful UV raysat ground level, ozone is harmful pollutantsformed from car, power and chemical plant exhaustirritate respiratory system and asthma; reduces lung function by inflaming and damaging lining of lungs
Combination of gases with water vapor and dustCombination of words smoke and fogForms when heat and sunlight react gases (photochemical smog)Occurs often with heavy traffic, high temperatures, and calm winds
1st smog related deaths were in London in 1873; death toll 500 people; can you imagine how much worse the atmosphere is now?!Limits visibilityDecreases UV radiationYellow/black color over citiesCauses respiratory problems and bronchial related deaths
Ride your bike
Tell your friends and family about pollution
Make sure your parents get pollution checks on their cars
Ride the school bus
Learn more; stay up to date
Join a group to stop pollution
Encourage your parents to carpool to work
Switch off lights, fan, heat, etc. when you leave the room
