1. Linking Cancer Rates & Chemical Release in Florida GIS 5100 Trisha Holtzclaw Javier Leung

2. Introduction  Florida ranks 32 nd in the county for cancer mortality and 23 rd in the county for cancer incidence.  The Environmental Protection Agency reports that in the year 2002 the reported disposal or releases of toxic chemicals in the state of Florida was 275,357,753 pounds.  Escambia and Santa Rosa counties are home to six Federal Superfund sites, three of which are located in central Pensacola.

3. Hypotheses Ho: There is NO relationship between cancer mortality and chemical release H1: There is a Negative relationship between cancer mortality and chemical release Ho: There is NO relationship between cancer incidence and chemical release H1: There is a Negative relationship between cancer incidents and chemical release

4. Florida Counties Above the National Average Cancer Mortality Rate Below 206 per 100,000 persons Above 206 per 100,000 persons Above 201.2 per 100,000 persons Below 201.2 per 100,000 persons Findings part 1 Comparison of National and Florida Age-Adjusted Cancer Mortality and Incidence Rates Fourteen Florida counties were over the national age-adjusted cancer mortality rate of 206 per 100,000 persons. Sixteen Florida counties were over the Florida age-adjusted new cancer incidence rate of 201.2 per 100,000 persons Counties Above the Florida Average Cancer Mortality Rate

12. Limitations & Conclusions Variables: Mortality & Chemical Release Correlation: Strength of the relationship is weak < 0 Regression: Chemical release not a single factor for cancer mortality predictor Variables: Incidence & Chemical Release Correlation: Strength of relationship is strong > 0.7 Regression: Chemical release not a single factor for cancer incidence predictor A correlation between the two variables has many limitations. These include health care access, income level, genetics, and population characteristics such as age, gender, and race.
