Air Pollution, Asthma, Triggers & Health - Research and Remediation Strategies

  1. 1. AIR POLLUTION & HEALTH A Workshop for Health Professionals Clean Air Council
  2. 2. Clean Air Council is a member-supported, non-profit environmental organization dedicated to protecting everyone's right to breathe clean air. The Council works through public education, community advocacy, and government oversight to ensure enforcement of environmental laws. Mission:
  3. 3. Environmental EducationEducation Avoiding environmental allergens and irritants is one of the primary goals of good asthma management. (American Academy of Pediatrics 2003) CLEAN AIR COUNCIL www.cleanair.org Integrate environmental education into clinical visits. Not all patients receive this level of comprehensive care. Comprehensive asthma interventions include in-home trigger inventories and environmental education.
  4. 4. CLEAN AIR COUNCIL www.cleanair.org Clinical Barriers Clinicians may lack knowledge of environmental triggers. Clinicians may be unaware of mitigation strategies. Clinics lack information/resources valuable to patients. Families leave without knowledge of triggers, how to reduce exposure or where to turn if they have questions. Time limitations.
  5. 5. CLEAN AIR COUNCIL www.cleanair.org Improve understanding of health issues associated with air pollution. Increase knowledge of mitigation strategies. Provide useful materials and resources. More effective and efficient care providers. Increase understanding of types and sources of air pollution. Workshop Objectives
  6. 6. CLEAN AIR COUNCIL www.cleanair.org Increase ability to individualize treatment plans. Increase capacity for building patient-provider relationships. Enhance quality of care and increase patient capacity for disease self management. Improve ability to communicate with patients about environmental exposures. Workshop Objectives
  7. 7. What is Air Pollution? CLEAN AIR COUNCIL www.cleanair.org Any particle or gas that harms your health, the environment, or causes property damage. Lead (Pb) Carbon Monoxide (CO) Particulate Matter (PM) Nitrogen Oxides (NOx) Sulfur Dioxides (SO2) Ozone (O3) EPA Regulated Air Pollutants
  8. 8. What is Air Pollution?What is Air Pollution? CLEAN AIR COUNCIL www.cleanair.org There are 1000s of unregulated compounds, pollutants and irritants that are equally or more dangerous.
  9. 9. Lead: A Toxic Metal CLEAN AIR COUNCIL www.cleanair.org * Gao, Modal & Lawrence, (2007) Lead effects on development and function of bone marrow-derived dendritic cells. Lead exposure can cause:  Brain damage  Nervous system disorders  Reproductive disorders  Kidney damage  Gastrointestinal distress  Low birth weight  Slowed neurological and behavioral development  Intensified allergic reactions *  Disruption in the development of certain immune system cells * Sources: Industrial processing. manufacturing, dust. 95% of lead that is inhaled is absorbed into the body.
  10. 10. Carbon Monoxide CLEAN AIR COUNCIL www.cleanair.org Colorless, odorless, tasteless gas. Common sources: Vehicles, cigarette smoke, furnaces, stoves, gas or oil burning space heaters, etc. Formed when fuel is not completely burned. Attaches to hemoglobin, reducing the amount of oxygen carried in bloodstream. Dangerous to everyone, especially those with asthma.
  11. 11. Created by fuel combustion. Nitrous Oxides CLEAN AIR COUNCIL www.cleanair.org Highly reactive, chemistry is driven by sunshine, and temperature and depends on surrounding substances.
  12. 12. Created when fuel containing sulfur (ex. coal, oil) is burned. Sulfur Dioxides CLEAN AIR COUNCIL www.cleanair.org Reacts in air to form sulfate, a form of particulate matter.
  13. 13. Particulate Matter (PM) CLEAN AIR COUNCIL www.cleanair.org Mixture of solid particles and liquid droplets (acids, organic chemicals, metals, dust, soil.) Common sources of toxic PM: Fuel-burning engines, industry (i.e. power plants, incinerators), wood burning, cigarettes. PM 10: Airborne particles larger than 2.5 mm but smaller than 10 mm. PM 2.5: Fine airborne particles that are < 2.5 micrometers in diameter. Health threat is proportionate to size and composition.

  19. 19. Air Pollution Research CLEAN AIR COUNCIL www.cleanair.org Assumption: Air pollution has a negative impact on our health. What is the evidence? How does air pollution affect asthma related outcomes?
  20. 20. Devlin et al. (1997) • Exposed healthy individuals to ozone (in lab). BAL results: • Temporary increases in inflammation. • Long-term increases in lactate dehydrogenase (enzyme released from injured epithelial cell walls). * Variable and complex immune response. Exposure Research CLEAN AIR COUNCIL www.cleanair.org
  21. 21. Devlin et al. (1997) • 2 hours of exposure to typical concentrations of ozone. • 1 hour of heavy exercise during exposure. Results: • Least-responsive individuals may experience no symptoms or lung function changes. • Most-responsive individuals experienced up to a 50% decrease in FEV1 (lung function) and have severe coughing, shortness of breath, or pain on deep inspiration. * Response to ozone can vary greatly by individual. Exposure Research CLEAN AIR COUNCIL www.cleanair.org
  22. 22. Kerhl et al. (2009) • Pre and post-ozone exposure dust mite challenge. • 8-hour ozone challenge. BAL Results: • Increases in inflammation 24 hours post ozone exposure (in comparison to pre-exposure inflammation). *Ozone increases airway reactivity/intensity of allergic response.

Exposure Research CLEAN AIR COUNCIL www.cleanair.org
  24. 24. Rossi et al. (1993) • Measured air pollution levels and emergency room visits in an industrial town (population 100,000). • 1 year = 232 emergency room visits for asthma. Results: • Significant correlation between air pollution levels and emergency room visits for asthma. * Air pollution linked to asthma exacerbations and health care usage.

  32. 32. Reducing Exposure to Outdoor Asthma Triggers Seasons and weather conditions - Pollution is more severe in Summer. - High pollution days are typically sunny, hot, humid with light winds. - Winter “inversions” can trap pollution at ground-level. Time of day -In morning, the sun comes out, and temperature rises, creating the conditions in which ozone is formed. -Ozone levels increase throughout the day, peaking in the afternoon. -Plan activities for early in the day or late evening. CLEAN AIR COUNCIL www.cleanair.org
  33. 33. • 0 - 50: Good. Air quality poses little/no risk. • 51 - 100: Moderate. Some risk for unusually sensitive individuals. • 101 - 150: Unhealthy for sensitive groups.

Enhance quality of care, increase patient capacity for disease self management & IMPROVED OUTCOMES! HCPs with a more specific knowledge of environmental asthma triggers and the available resources can provide more comprehensive care. Conclusions -Increases patient’s awareness. -Empower patients to create and ask for change in their homes and their communities.
