Inequalities in cumulative environmental burdens among three urbanized counties in California
:<3:
Main method: Cumulative Environmental Hazard Inequality Index (CEHII)
Target: assess inequalities by racial-ethnic and poverty status in exposure to air pollution and heat stress in 3 urban counties
3 counties: Los Angeles, Alameda, and San Diego
Significant interactions between heat stress and air pollutants causes disproportionate burdens
Hazardous sources
Metric heat stress
Absolute measures
Relative measures
Risk: Increasing hot weather affects health
Summer heat waves causes disease and premature death due to less acclimated to high temperatures
Chronic problem in arid climates
Air pollution
PM 2.5 - fine particular matter
Diesel PM - diesel particular matter
NO2 - traffic related air pollution
Main victim: Marginalized groups
minority populations
elderly
poor
Background
Higher environmental stressors in communities of color and low-income
Increasing environmental hazard potentially causes health disparities
