AIR POLLUTION & HEALTHA Workshop for Health Professionals
Clean Air Council
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:
Environmental Education Education
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.
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.
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
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
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
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.
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.
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 oxygencarried in bloodstream.
Dangerous to everyone, especially those with asthma.
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.
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.
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.
Ozone (O3)
CLEAN AIR COUNCIL www.cleanair.org
NOx + Sunshine/Heat + VOCs Ozone
“Good up high,bad nearby”

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?
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
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
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
Morishita et al. (2004) • Induced an allergic airway disease in a group of rats (oval-
bumin exposure).• Exposed allergic and non-allergic to air from urban Detroit
air (mobile lab).
BAL Results: • Exposure to particulate matter induced inflammation
(eosinophils, proteins) most in rats with the allergic disease.
* Non-specific allergic response is triggered by particulates found in urban air.
Exposure Research
CLEAN AIR COUNCIL www.cleanair.org
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.
Exposure Research
CLEAN AIR COUNCIL www.cleanair.org
Burnett et al. (1994)• Tracked air pollution levels, health care usage, and
absenteeism.• 16 cities• 10 years • 720,519 asthma-related admissions.
Results: • Days with higher ozone levels were associated with higher
rates of absenteeism, and more visits to doctors, hospitals and emergency rooms.
Exposure Research
CLEAN AIR COUNCIL www.cleanair.org
Jerrett et al. (2009)• Paired air pollution data in 96 cities with cause of death data
for almost 500,000 people (118,777).
Results: • Significant increase in the risk of death from respiratory
causes associated with increases in ozone concentration.
Exposure Research
CLEAN AIR COUNCIL www.cleanair.org
Gordon et al. (2000) (Review article) “Cardiovascular Toxicity of Inhaled Ambient Particulate Matter”
• PM exposure increases:-Blood pressure-Heart rate-Heart rate variability-Changes in blood plasma and blood coagulation-Risk of heart attack, stroke, etc.
Exposure Research

transportation and goods movement-related activities, etc).• Neighborhood/community level (ie. motor traffic, autobody shops, dry-
cleaners, nail salons, etc).• Rural environments (ie. pollen).
Indoors• Home• Homes of friends, family, etc• School• Work
Environmental Asthma Triggers
CLEAN AIR COUNCIL www.cleanair.org
• Ozone • Particulate Matter• Industrial Processing (metal dust, toxic fumes, etc)• Vehicle exhaust• Road dust• Pollen• Mold spores• Cold weather• Auto-body practices (paint, engine work, etc)• Dry-cleaning emissions• Construction• Chlorine• BBQ/Grill• Fires, Burn barrels• Fireworks
Outdoor Asthma Triggers & Sources
CLEAN AIR COUNCIL www.cleanair.org
Reducing Exposure to Outdoor Asthma Triggers
Tools for Minimizing Exposure:
-Air Quality Data (pollution, weather, pollen)
-Advocacy (patient, community, political)
Reduce time spent outdoors on days with higher concentrations of air pollution & pollen.
Reduce intensity and duration of outdoor activity during times that pollution is highest.
CLEAN AIR COUNCIL www.cleanair.org
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
• 0 - 50: Good. Air quality poses little/no risk.
• 51 - 100: Moderate. Some risk for unusually sensitive individuals.
• 101 - 150: Unhealthy for sensitive groups. Sensitive groups include children, adults active outdoors, and lung disease patients.
• 151 - 200: Unhealthy. Risk for anyone active outdoors.
• 201- 300: Very Unhealthy. Risks for general population.
• 301 – 500: Hazardous. Emergency conditions.
