Air Pollution : 

Air Pollution Types of pollution How does air move How do you measure air pollution Ozone Particulate Matter Connections to human health

Why should you come to our session? : 

Why should you come to our session? In Michigan, • 9.3% (701,300) adults currently have asthma. Southwest MI experiences 18 days every year with air quality below EPA standards. Figure for the US only. http://www.epa.gov/air/airtrends/sixpoll.html

Air Pollution : 

Air Pollution Generally anything that enters the air that is harmful to organisms (including plants) Some pollution comes from humans, others can come from plants and the environment (forest fires, dust, soil, etc.) Air quality has improved for some pollutants, and declined for others.

NAAQS: 

NAAQS National Ambient Air Quality Standards Set by the EPA for wide-spread pollutants from numerous and diverse sources that are considered harmful to human health and the environment. Available at http://www.epa.gov/ttn/naaqs/

The Great Lakes Airshed: 

The Great Lakes Airshed Air travels from one region to the next, spreading pollution. We receive pollution from Gary, Chicago, and Milwaukee. We give pollution to Canada and New England.

How can we tell if air quality is getting better or worse? : 

How can we tell if air quality is getting better or worse? Monitoring different pollutants requires different techniques. Some are really easy, and some are quite complex.

Your task today…: 

Your task today… To look at two different ways to monitor air pollution To predict where you would find high concentrations of ozone and particulate matter To examine patterns across the US and compare Michigan to other places

Ozone detectors: 

Ozone detectors See student handout for particular instructions. Safety first: Glassware is hot! Use pot-holders. Also, wear gloves when handling Potassium Iodide. We will make the paste first, and then let it cool while we work on other activities

Particulate matter sticky traps: 

Particulate matter sticky traps Student handout has instructions about how to make these. Predict sites that you think might have high PM or high ozone levels, and write this on your sheet. We will look at some samples under a microscope

Particulate Matter across the US: 

Particulate Matter across the US Green=good Yellow= moderate Orange= unhealthy Red=really unhealthy

Ozone levels: 

Ozone levels Highest in summer, lowest in winter Ozone strips are graded by color: No color change=very low ozone Lavender= medium ozone Dark purple=high ozone The ozone levels detected will be affected by humidity, with high humidity giving higher readings.
