Document Summary

Geog 221 lecture 4. 3 air pollution health effects. Relationship between exposure to air pollution and levels of education. Local levels of air pollution in disadvantaged areas are higher than the city-wide averages used in the analyses, so the observed effect is due simply to measurement error. Interpolated no2 levels: toronto: trying to map out areas of the city that are more exposed to no2, living next to highways: noise and air pollution people don"t tend to live near there. Low income groups tend to live close to these areas of high pollution. Intra-urban variability in measurements of air pollution: research is getting more refined wearing monitors around the city to measure exposure to air pollution. Particle retention in human lungs: mexico city and vancouver: more polluted city: more accumulation of air pollutants in human matter, much variability in exposure due to unequal environments in. Mexico city: much less variability in vancouver, smaller social differences.
