Unformatted text preview: d. The pyramid demonstrates that as severity decreases the number of people affected increases. Health Endpoints Associated with Increased Air Pollutants Levels
Mortality: All non-accidental mortality causes Hospital Admissions: Cardiovascular and Respiratory Hospital Admissions Emergency Room Visits: Visit to an emergency department Asthma Symptom Days: Exacerbation of asthma symptoms in individuals with diagnosed asthma Restricted Activity Days: Days spent in bed, missed from work, and days when activities are partially restricted due to illness Acute Respiratory Symptoms: Respiratory-related symptoms such as chest discomfort, coughing and wheezing Population at Risk
Although everyone is at risk from the health effects of air pollution, certain sub-populations are more susceptible. Individual reactions to air contaminants depend on several factors such as the type of pollutant, the degree of exposure and how much of the pollutant is present. Age and health are also important factors. The elderly and people suffering from cardio-respiratory problems such as asthma appear to be the most susceptible groups. Children and newborns are also sensitive to the health effects of air pollution since they take in more air than adults for their body weight and consequently, a higher level of pollutants. People who exercise outdoors on hot and smoggy days are also at greater risk due to their increased exposure to pollutants in the air. Leading Causes of Hospitalization Respiratory and cardiovascular diseases are among the leading causes of hospitalization in Canada. In 1996-1997 there were 3.16 million hospital admissions in Canada of which cardiovascular and respiratory diseases accounted for 15% and 9%, respectively. Air pollution exacerbates the condition of people with respiratory and cardiovascular diseases and causes measurable increases in the rates of hospitalization for these diseases. We do not yet understand the role of air pollution in causing these illnesses in the Canadian population. Leading Causes of Death Cardiovascular and respiratory diseases are among the leading causes of death in Canada. In 1997, 37% and 9% of over 200 000 deaths were related to cardiovascular and respiratory diseases respectively. Air pollution causes measurable increases in non-accidental mortality. Esti...
