Exposure to Extremely Hazardous Substances

The likelihood of exposure to hazardous substances based on economic status and race

Paper by J. Chakraborty. 2001. Risk Analysis, 21(5): 883-895

Presented by Jeffrey Tate, Enivronmental Studies, Geog 370, 3/1/2010

differences in exposure
Differences in Exposure
  • Problem: Whether or not minorities and people of lower economic status are more likely to be exposed to extremely hazardous substances
  • Hypothesis: Minorities and people below the poverty line have significantly more exposure to extremely hazardous chemicals than whites and those above the poverty level
methods
Methods
  • Site: Hillsborough County, Florida
  • Determined within the county: Number of facilities that use extremely hazardous substances, where they are, what substances they house (from RMPs)
  • Estimates for 1997 based on Census data were used to determine the racial composition and poverty status of the population in the county
  • The locations of the facilities were geocoded onto the street network and used with the Census data to see what groups of people were close to the facilities
results
Results
  • Non-white people had a higher risk of potential exposure to accidental releases of extremely hazardous chemicals than white people
  • People below the poverty line had a higher risk of potential exposure than those above the line
conclusions
Conclusions
  • There is a clear difference between the potential exposure of hazardous substances between minorities and whites, and those above the poverty line and below
  • There are clear racial and economic inequalities in the distribution of accidental exposure to hazardous substances
  • Criticisms
  • Does not determine whether communities or facilities come first
  • Does not examine actual health effects due to exposure of hazardous substances
