Expected Learning Outcomes Viewers will learn: • Sources of outdoor and indoor air pollution • History of air quality incidents • National air quality regulation measures • Personal measures to impact air pollution
Introduction • Air pollution is defined as the “presence in the air of substances that interfere with health, comfort and safety” (Moeller, 2005). • Industrialization compounded the problem with motor vehicles being a significant contributor to air pollution. Reference: Moeller D.W, 2005. Environmental Health. Harvard University Press
Air Quality • Air Quality Industrial chemicals Ozone Particulates CO Radon Reference Pope C.A, Ezzati M, Dockery D.W, 2009. Fine-Particulate Air Pollution and Life. Expectancy in the United States. New England Journal of Medicine. 360: 376-386.
Air Quality Continued Consequences • Asthma • Other respiratory effects • Increased Hospitalizations • Increased Lung cancer rates • Increased Mortality Who is most susceptible? • Infants and children • Elderly • Those who are ill Reference: Maryland Department of the Environment, 2009.

Statistics Historical Data on Air Pollution 1930: Death of 60 people in Belgium • 1948: Death of 20 people in Pennsylvania • 1952: Death of 4,000 people in London • 1970: Clean Air Act passed Reference: Stone R, 2002. “Air Pollution: Counting the Cost of London’s Killer Smog”.Science 298, no. 5599, 2106- 2107 . Environmental Protection Agency, 2009. Clean Air Act. Available at www.epa.gov.air/caa/index.html. Retrieved on April 4, Reference:
The Clean Air Act • Passed by Congress in 1970. Amended in 1990 • Addresses Air pollution from all sources. • Established the Environmental Protection Agency (EPA, 2009) • Sets standards and regulate compliance • Role of EPA: Monitoring and enforcement Funding and scientific research Assistance to States Reference: Environmental Protection Agency, 2009. Clean Air Act. Available at www.epa.gov.air/caa/index.html. Retrieved on April 4, 2009
Sources of Ambient Air Pollution • Forest fires • Wood smoke • Dust and other particulates • Vehicle emissions • Power plants • Heating • Ozone • Carbon emissions • Sulfur emissions Reference: Moeller D.W, 2005. Environmental Health. Harvard University Press
Carbon Emissions • Greatest source of carbon emission is motor vehicles • Produce 56% of emissions nationwide (EPA, 2000). • Health effects: heart disease, preterm birth, birth defects (EPA, 2000). • Accounts fro 500 accidental deaths, 15, emergency dept visits (CDC, 2007).

Arguments For Clean Air Recent published research study ( Pope, Ezzati and Dockery, 2009) showed a 3 year increase in life expectancy due to reduction in air pollution. Another study by EPA(2009) found that the economic value of avoiding these health effects was $24 billion over a period of 24 years, compared to a cost of $6 billion to implement the program.

Air Quality Regulatory Measures • Direct Regulation • Subsidies and Incentives • Tax Credits • Pollution Taxation • Process Improvement Reference: Environmental Protection Agency, 2009. Clean Air Act. Available at ww.epa.gov.air/caa/index.html.Retrieved on April 4, 2009.
Indoor Air Quality • Now getting more attention • Sources of Indoor air pollution: 1) Natural: microorganisms, natural gas. 2) Man-made: building and construction material, wood burning fireplaces, candles, air fresheners, furnishings like carpet tobacco. Reference: Moeller D.W, 2005. Environmental Health. Harvard University Press
Indoor Air Quality Continued • Addressing this involves looking at multiple contributory factors • Basic hygiene and sanitation is a very big factor (Moeller, 2005) Reference: Moeller D.W, 2005. Environmental Health. Harvard University Press
Measures to Reduce Carbon Emissions at the Individual Level • Walk or use public transport • Carpooling • Vehicle Servicing • Carbon efficient vehicles • Green products • Recycling Reference: Clean Air Agenda, 2009. Canadian Environmental Agency Available at http://www.ec.gc.ca/cleanair-airpur/Home-WS8C3F7D55-1_En.htm. Retrieved on April 11, 2009
Measures to Improve Air Quality at National Level • Kyoto Protocol (Moeller, 2005). Goal to reduce emission by 5% • Reduction of emission levels • Revision of Standards • Improvement of process • Enforcement of law Reference: Environmental Protection Agency, 2000. Office of Air Quality Planning & Standards. How Carbon Monoxide Affect the Way we Live and Breath. Moeller D.W, 2005. Environmental Health. Harvard University Press
Conclusion • Air quality has significant implication on people, animals agriculture. • Much still remains to be done. • Education provides knowledge to implement change and take responsibility.
Outcome of this Presentation • Increase audience knowledge on topic • Use of this knowledge to motive actions to reduce air pollution
