Environmentally-Friendly Lawn Care • Who we are • Johnson County Environmental Department (JCED) • Kansas Small Business Environmental Assistance Program • K-State program • Office here at Extension • Provide environmental assistance to small business – free, confidential, non-regulatory Low Emission Lawn Care www.sbeap.org

3. Low emission lawn care? • Why - environmental impact • Ozone • Health impacts A conventional lawn mower pollutes as much in an hour as 40 late model cars. Low Emission Lawn Care www.sbeap.org

4. Some pollution facts • Gas-powered tools contribute 5% of the U.S. air pollution. • Lawn and garden equipment users spill 17 million gallons of fuel (more than Exxon’s Valdez in the Gulf of Alaska) each year when refilling outdoor power equipment. Low Emission Lawn Care www.sbeap.org

5. Program overview • Introductions and program overview • Defining the air quality problem • what is ozone • what are the health issues • how does this relate to lawn care and our program? • Opportunities to address the problem • low-emission equipment selection and maintenance • low-maintenance turf options • rain gardens Low Emission Lawn Care www.sbeap.org

6. Program overview • Why is this important to master gardeners? • Common questions – expert advice • Personal and community health Low Emission Lawn Care www.sbeap.org

7. How do we measure air pollution levels? An air quality monitor is an instrument that takes a sample of air and measures the amount of an air pollutant such as ozone or particulate matter in the air. All air monitors in the national network have to meet the same strict quality control standards so that data from all sites across the country is accurate and comparable.

12. What is Ozone? Ozone, or smog, is an odorless, colorless gas composed of three oxygen atoms. • Ozone occurs naturally about 10 to 30 miles above the earth and protects us from the sun’s harmful ultraviolet rays. • However, at ground-level in the air we breathe, ozone poses serious risks to human health. Low Emission Lawn Care www.sbeap.org

13. O3 = + Where Does Ozone Come From? Ozone is not emitted directly into the air but is created by a chemical reaction in the air: VOC + NOx + Heat + Sunlight = Ozone • Volatile Organic Compounds (VOC) and Nitrogen Oxides (NOx) come from cars, trucks, buses, power plants, industrial facilities, citizen activities and other sources. Low Emission Lawn Care www.sbeap.org

14. Ozone • Is a Seasonal Pollutant • Highest pollution levels in summer • (May-September) • Hot, sunny afternoons & evenings typically have the highest ozone concentrations Low Emission Lawn Care www.sbeap.org

15. What is Ozone Pollution? Every day, the average adult breathes over 3,000 gallons of air, and children breathe even more air per pound of body weight. Ozone pollution has many effects on public health. Some of these are very serious. In the air we breathe, ozone poses serious risks to human health. Environmental repercussions - Ozone also adversely affects domestic and native plants and animals. Low Emission Lawn Care www.sbeap.org

16. Why is Ozone Bad to Breathe? Ozone can irritate lung and airways, and cause inflammation much like a sunburn on your lungs. • Ozone can aggravate respiratory illnesses such as asthma. • 10 to 20 % of all summertime respiratory-related hospital visits in the US are associated with ozone pollution. Low Emission Lawn Care www.sbeap.org

17. Health Effects of Exposure to Ozone Coughing • Nose and throat irritation • Chest pain • Reduced lung function • Increased susceptibility to respiratory illnesses • Aggravation of asthma • Children and people with chronic lung diseases are particularly at risk Low Emission Lawn Care www.sbeap.org

18. Ozone Pollution • WHERE IS IT COMING FROM? • Possible sources • Kansas City citizens and businesses create our own urban air pollution. • Ozone precursor compounds are transported to the Kansas City urban area from Mexico, Texas, Arkansas, & Oklahoma by our south winds. • Combination of the above scenarios Low Emission Lawn Care www.sbeap.org

19. What Makes a Bad Air Day (Ozone) in South Central Kansas? Hot temperatures… + Sunny skies… + South winds??? = unhealthy ozone levels • Johnson County Environmental Department and Kansas Department of Health and Environment (KDHE) are working together to determine: • What local sources are significant contributors • The impact of weather and transport from other upwind urban/industrial areas Low Emission Lawn Care www.sbeap.org

21. What is Particulate Matter? Airborne “particulate matter” consists of many different substances suspended in the air in the form of particles (solid and liquid droplets) that vary widely in size. Low Emission Lawn Care www.sbeap.org

22. Cross section of a human hair (magnified to 60 mm) Coarse Particles (10 mm) Fine Particles (2.5 mm) What are Fine Particles? Fine particles are only a fraction of the size of a human hair. • Fine particles come from a variety of sources such as diesel trucks and buses, construction equipment, power plants, woodstoves, and wildfires. • Fine particles can also be formed in the atmosphere when gases are transformed by chemical reactions in the air. Low Emission Lawn Care www.sbeap.org

23. Why are Fine Particles Bad to Breathe? Scientific studies have linked fine particles, with a series of significant health problems, because they easily reach the deepest parts of the lungs. • In the US, particulate matter, especially fine particles, is responsible for 15,000 premature deaths every year. • Diesel exhaust, a significant source of fine particles, can cause lung cancer. Low Emission Lawn Care www.sbeap.org

24. Health Effects of Exposure to Fine Particles Premature death • Respiratory related hospital admissions and emergency room visits for cardiac and other conditions • Aggravated asthma • Acute respiratory symptoms • Chronic bronchitis • Decreased lung function (shortness of breath) • People with existing heart and lung disease, as well as the elderly and children, are particularly at risk Low Emission Lawn Care www.sbeap.org

25. What Can You Do? • Avoid strenuous outdoor activities when ozone levels are high • Share a ride or take public transportation • Cut your grass after 6 pm • Refuel your car after 6 pm (fuel when it’s cool) • Combine your errands into one trip • Purchase low-emitting and fuel efficient vehicles (www.epa.gov/autoemissions) Low Emission Lawn Care www.sbeap.org
