Institute for Tribal Environmental ProfessionalsIndoor Air Quality in Tribal Communities Mansel Nelson, ITEP Leading Causes of Lung Cancer
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
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
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
Another Leading Cause of Cancer • Asbestos exposure • Highest risk • Mining, milling, manufacturing of asbestos • Use asbestos and its products www.nau.edu/eeop
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
Synergistic Connections(Asbestos and Smoking) Exposure to asbestos increases risk of developing lung disease Risk made worse by smoking www.nau.edu/eeop
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
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
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
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
Radon • Radon in air is ubiquitous • Radon: odorless, colorless, radioactive gas derived from decay of uranium in soil • Found in outdoor air and indoor air of buildings • Form of radiation that damages lung tissue • # 1 cause of lung cancer among non-smokers • Estimated 21,000 deaths year, rising • Smoking increases your risk 4 times! • Elevated indoor levels found in every state www.nau.edu/eeop
Where does radon come from? • Caused by breakdown of Uranium in earth’s crust. Present in almost all rock, soil, and water • Amount of radon in soil depends on soil chemistry, which varies greatly from one house to next • Moves up through ground into atmosphere, where it can potentially enter your home through cracks/holes in foundation
Radon “Daughters” www.nau.edu/eeop
4 day Radon-222 a,g 3 min Polonium-218 a,g 27 min Lead-214 b,g 20 min Bismuth-214 b,g 0.2 ms Polonium-214 a,g Lead-210 22 yrs b,g Bismuth-210 5 day b,g Polonium-210 138 day a,g Lead-206 Stable Radon Decay Products Po-218 and Po-214 Deliver majority of radiation dose to lungs
Radon in Buildings • From soil • Lower parts of building at greatest risk • “Stack effect” • Buildings above the ground do not need to be tested www.nau.edu/eeop
Radon (cont.) Red alert - radon level above 4 pCi/L Yellow alert - radon levels between 2 and 4 pCi/L Average radon indoor air about 1.3 pCi/L www.nau.edu/eeop
Radon Testing www.nau.edu/eeop
Surgeon General Report Second-Hand Smoke Single greatest avoidable cause of disease and death www.nau.edu/eeop
Surgeon General 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
Surgeon General 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
Smoke Free Pledge http://www.epa.gov/smokefree/
Surgeon General 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
Surgeon General Report (cont.) The scientific evidence indicates there is no risk-free level of exposure to secondhand smoke www.nau.edu/eeop
Surgeon General 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
What does it look like? fibrous, friable (able to crumble) and fluffy, almost like a muddy brown or white cotton wool Asbestos
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
Where is Asbestos Found? Acoustic insulator Thermal insulation Fire proofing Other building materials Brake pads / drum Brake linings Asbestos-cement www.nau.edu/eeop
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
Health Risk Intact, undisturbed asbestos-containing materials generally do not pose a health risk www.nau.edu/eeop
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
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
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 that is trained to remove or contain the fibers. www.nau.edu/eeop
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
