1. Institute for Tribal Environmental ProfessionalsIndoor Air Quality in Tribal Communities Mansel Nelson, ITEP Leading Causes of Lung Cancer

2. First Leading Cause of Lung Cancer • Smoking is leading cause of lung cancer  • Causes an estimated 160,000 deaths in the U.S. every year (American Cancer Society, 2004  • Rate among women is rising  • Now exceeds breast cancer www.nau.edu/eeop

3. Second Leading Cause of Lung Cancer Radon is number one cause of lung cancer among non-smokers  Second leading cause of lung cancer  Responsible for about 21,000 lung cancer deaths every year  About 2,900 among people who have never smoked www.nau.edu/eeop

4. Third Leading Cause of Lung Cancer Secondhand smoke is third leading cause of lung cancer Estimated 3,000 lung cancer deaths every year  About 1,000 never smoked; about 2,000 former smokers www.nau.edu/eeop

5. Another Leading Cause of Cancer • Asbestos exposure • Highest risk • Mining, milling, manufacturing of asbestos • Use asbestos and its products www.nau.edu/eeop

6. Synergistic Connections(Radon and Smoking) Radon and smoking are synergistic Smokers: 62 of 1,000 people will die of lung cancer Never-smokers: 7.3 of 1,000 for never-smokers Never-smoker at 1.3 pCi/L (indoor average): 2 in 1,000 chance of dying from lung cancer Smoker at 1.3 pCi/L (indoor average): 20 in 1,000 chance of dying from lung cancer www.nau.edu/eeop

7. Synergistic Connections(Asbestos and Smoking) Exposure to asbestos increases risk of developing lung disease Risk made worse by smoking www.nau.edu/eeop

8. Smoking

9. Smoking Harms nearly every bodily organ Causing many diseases, degrades health Estimated 438,000 deaths (nearly 1 of 5 deaths) each year in U.S. More than by all deaths from human immunodeficiency virus (HIV), illegal drug use, alcohol use, motor vehicle injuries, suicides, and murders combined www.nau.edu/eeop

10. Smoking (cont.) • Cancer is second leading cause of death • First disease directly linked to smoking • Risk of dying from lung cancer • 23x higher among men • 13x higher among women • Smoking causes cancers of bladder, oral cavity, pharynx, larynx (voice box), esophagus, cervix, kidney, lung, pancreas, and stomach, and acute myeloid leukemia www.nau.edu/eeop

11. Smoking (cont.) Smokers 2–4 times more likely to develop coronary heart disease Smoking doubles a person’s risk for stroke Smokers more than 10x as likely than nonsmokers to develop peripheral vascular disease www.nau.edu/eeop

12. Smoking (cont.) Causes tenfold increase in risk of dying from chronic obstructive lung disease Many adverse reproductive and early childhood effects, including increased risk for infertility, preterm delivery, stillbirth, low birth weight, and sudden infant death syndrome (SIDS) Postmenopausal women smokers have lower bone density www.nau.edu/eeop

13. Radon

14. Radon (cont.) Radon in air is ubiquitous Found in outdoor air and indoor air of buildings of all kinds  No known safe level of radon www.nau.edu/eeop

15. Radon (cont.) Red alert - radon level above 4 pCi/L (pico Curies per Liter) Yellow alert - radon levels between 2 pCi/L and 4 pCi/L Average radon indoor air about 1.3 pCi/L www.nau.edu/eeop

16. Radon in Buildings • From soil • Lower parts of building at greatest risk • “Stack effect” www.nau.edu/eeop

17. Radon Testing www.nau.edu/eeop

18. Second-Hand SmokeEnvironmental Tobacco Smoke (ETS)

19. Surgeon General’s Report Second-Hand Smoke Single greatest avoidable cause of disease and death www.nau.edu/eeop

20. Surgeon General’s Report (cont.) Millions of Americans, children and adults, still exposed to second-hand smoke Second-hand smoke exposure causes disease and premature death in children and adults who do not smoke www.nau.edu/eeop

21. Surgeon General’s Report (cont.) Children exposed to secondhand smoke at increased risk for • Sudden infant death syndrome (SIDS) • Acute respiratory infections • Ear problems • More severe asthma www.nau.edu/eeop

22. Smoke-Free Pledge http://www.epa.gov/smokefree/

23. Surgeon General’s Report (cont.) • Exposure of adults to secondhand smoke has immediate adverse effects • Cardiovascular system and causes • Coronary heart disease • Lung cancer www.nau.edu/eeop

24. Surgeon General’s Report (cont.) The scientific evidence indicates there is no risk-free level of exposure to secondhand smoke www.nau.edu/eeop

25. Surgeon General’s Report (cont.) • Eliminating smoking in indoor spaces fully protects nonsmokers • Following actions DO Not protect nonsmokers • Separating smokers from nonsmokers • Cleaning the air • Ventilating buildings www.nau.edu/eeop

26. Asbestos

27. What does it look like? fibrous, friable (able to crumble) and fluffy, almost like a muddy brown or white cotton wool Asbestos

28. Asbestos – Health Impacts Lung Cancer Asbestosis – serious, progressive, long-term non-cancer disease of the lungs Mesothelioma – rare form of cancer found in thin lining (membrane) of lungs

29. Where is asbestos found? Acoustic insulator Thermal insulation Fire proofing Other building materials Brake pads / drum Brake linings Asbestos-cement www.nau.edu/eeop

30. Isn’t asbestos banned? Asbestos is NOT a banned substance In 1989, EPA banned all NEW uses of asbestos Uses established before 1989 are still allowed www.nau.edu/eeop

31. Health Risk Intact, undisturbed asbestos-containing materials generally do not pose a health risk www.nau.edu/eeop

32. Schools Perform inspections and re-inspection every three years of asbestos-containing material Asbestos management plan Notification to parent, teacher, and employee organizations Provide custodial staff with asbestos-awareness training www.nau.edu/eeop

33. Work Place U.S. Occupational Safety and Health Administration (OSHA) has issued revised regulations covering asbestos exposure In construction, there are special regulated-area requirements for asbestos removal, renovation, and demolition operations www.nau.edu/eeop

34. Home Materials containing asbestos that are not disturbed or deteriorated do not, in general, pose a health risk and can be left alone If you are concerned, contact EPA or Health Department - Test your home - Locate a company trained to remove or contain fibers www.nau.edu/eeop

35. Synergism of Asbestos and Smoking Cigarette smoke and asbestos together significantly increase your chances of getting lung cancer If you have been exposed to asbestos, you should stop smoking This may be the most important action that you can take to improve your health and decrease your risk of cancer www.nau.edu/eeop
