  1. The Baltimore Environment and Health DisparityPart 3 Michael A. Trush and Pat Tracey Johns Hopkins Center in Urban Environmental Health MPT Connections Colloquium Jan.20, 2006

  2. BALTIMORE MEMORY STUDYDirected by Dr. Brian S. Schwartz • Noted disparities in cognitive function by race/ethnicity (Env. Health Perspectives Vol.112, March 2004) • Lower median household income and assets • 30% greater bone lead level • Higher PCB levels in serum • Greater % population report a history of stroke • Greater % of population obese as a function of multi-dimensional neighborhood hazards index (MNHI). MNHI takes into consideration ~12 neighborhood variables.

  4. Some types of fish are a major source of organic mercury exposure to humans. Thus, we need to consider the health benefits of eating these fish versus the risk of mercury exposure in them.This is illustrated below.

  16. SUMMARY • Preventing the occurrence of health disparity is more economical than treating disease. • Clearly, the relationships between environmental factors and health disparity are complex. • Solutions to addressing this relationship need to include: environmental public health tracking; better data linkage at the individual and community levels; involving community groups in planning and database gathering from the beginning. This will require a broad view of environmental health and multidisciplinary approaches .
