  1. Environmental Integrity and the Incidence of Cancer Pooja Mehra Thomas Shahady

  2. Central Questions Concerning Environmental Degradation • Human Environment Changes to Ecological Integrity • Patterns in Lifestyle • Land Consumption and Chemical Use • “A Part of Nature” or “Apart from Nature”

  3. Does Degradation of Water Quality Impact Our Lives • A Critical Question when arguing for Protection • Drinking water from distant sources – reservoirs and watersheds • Degradation impacts to distant places – Chesapeake Bay • Local Impact to our Health – Are we paying a price to our health? • Costs for treatment.

  4. Study • Collection of Water Quality Data in Area • Use of Fish to reflect long term water quality changes • Hitt and Hendryx 2010 • Analyze Cancer Data from Cancer Registry in Area (Pooja Mehra – UVa Medical Student) • Calculation of cancer incidence based on reported cases per population of area. • Look for correlations with Data • Simple regressions and ANOVA analysis

  5. Electroshock the Fish

  6. Areas of Study 24503 24501 24502 24588

  7. Table 1 – Correlation Coefficients and Statistical Significance of all cancer types tested in our study. A simple ANOVA was used to test significance.

  8. Breast Cancer

  9. Total Cancer

  10. Blood

  11. Implications

  12. Breast Cancer Triggers and the Environment • Risk factors for breast cancer: • Early onset of menstruation • Late menopause • Hormone replacement therapy • Birth control pills • Exposure to certain chemicals, in plastics and pesticides • Exposure to radiation • Xenoestrogens are chemicals that mimic estrogens. They can be found in lawn pesticides and certain types of plastic. • BPA is used in polycarbonate plastic bottles, lining of tin cans, and dental sealants. • Synthetic estrogen can disrupt a human’s endocrine system - DDT was the first “intentionally released” chemical to be found estrogenic.

  13. Links to Suburban Lifestyle • BPA • Lawns and Pesticides • DEA and TEA

  14. Government Says 2 Common Materials Pose Risk of Cancer – June 2011 Formaldehyde Styrene

  15. Conclusions • Difficult to make direct links to cancer but the relationship exists. • Our past work does link water quality degradation to destructive land use. This research provides a potential cancer link. • Is there a community planning risk here? Do land use decisions impact our health through the creation of urban sprawl and suburbs forcing suburban lifestyle choices?

  16. Environmental Improvements and Health • Rejection of Suburban Lifestyle • Local unpackaged foods and beverages • Household and clothing goods • Lawns and household environments • Broader solutions require changes in development patterns • Less land disturbance and consumption • Stream restoration • Clean energy and transportation
