Title: Research Physical Scientist

EPA Division: Human Exposure and Atmospheric Sciences Division

EPA Branch: Exposure Modeling Research Branch

Bradley’s research is working to support the development of sustainable and healthy communities, enhance human exposure modeling, and provide information to support community-level efforts through voluntary and regulatory activities. Some of this research involves cumulative risk assessment, including chemicals and non-chemical factors that affect the assessment of risk. I have also provided scientific and technical support on guidance documents such as “Protect Your Family from Lead,” wrote sections of “Asbestos in Public Buildings: A Report to Congress,” wrote sections of a major review of EPA risk assessment practices, including leading the chapter on Uncertainty and Variability, in “An Examination of EPA Risk Assessment Principles and Practices,” and wrote many other technical documents used in EPA policymaking, rulemaking, and enforcement.

Select Presentations:

  • "Risk Analysis to Support Standards for Lead in Paint, Dust, and Soil," 1998. Technical lead for this risk analysis, which supported the proposed regulation which set national health-based standards for lead in dust, paint, and soil, which was reviewed at public meetings, the EPA Science Advisory Board, and the US Office of Management and the Budget.
  • "Supplement to the Risk Analysis to Support Standards for Lead in Paint, Dust, and Soil," 2000. Provided technical analysis to support the response to public comment, review by the EPA Science Advisory Board, and review by the US Office of Management and the Budget.
  • "Basis for Educational Recommendations on Reducing Childhood Lead Exposure," 2000.
  • “A Review of Studies Addressing Lead Abatement Effectiveness: Updated Edition," 1998.
  • "Seasonal Trends in Blood Lead Levels in Milwaukee," 1996.
  • "Verification of PCB Spill Cleanup by Sampling and Analysis," 1985. Also, "Sampling Designs for Verification of Cleanup and PCB Spill Sites," B. Schultz and D. Cox, Proceedings of the Section on Survey Research Methods, American Statistical Association (the only non-peer reviewed publication here, though it was extracted from a peer-reviewed publication), 1985.
