Air pollution harms human health and the environment.Transportation, Factories, Forest firesAre common sources of air pollution
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
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
Nitrogen Dioxide •present in car exhaust and power plants •affects lungs and causes•reddish, brown gas wheezing; increases chance of respiratory infection•produced when nitricoxide combines withoxygen in theatmosphere
Particulate Matter •can build up in•particles of respiratorydifferent sizes systemand structuresthat are released •aggravates heart and lunginto the disease;atmosphere increases risk of respiratory•present in many infectionsources includingfossil fuels,dust, smoke, fog,etc.
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
