SHERP II2002 Focus• Epidemiology research
• Air toxics (HAPS)
• Houston-specific data
2005 Evolving Focus• Multidisciplinary research
– Env. Health Paradigm framework
• Air pollutants of concern in Houston-Galveston
• Exploit exposure and population characteristics that are unique to Houston in order to address key scientific question in the exposure-health effects continuum
