Summary of exposure metric comparisons.

Primary Metric Comparison Metric Goal for Comparison is to Understand Differences Between:
1. PM2.5-pers(m) 2. PM2.5-out(m) personal and outdoor, measured concurrently
1. PM2.5-pers(m) 3. PM2.5-out(p) personal and predicted outdoor
1. PM2.5-pers(m) 4. PM2.5-out(nm) personal and predicted outdoor using a simplified approach
1. PM2.5-pers(m) 5. PM2.5-in(m) personal and ambient-derived infiltrated indoor
1. PM2.5-pers(m) 6. PM2.5-in(p) personal and predicted ambient-derived infiltrated indoor
1. PM2.5-pers(m) 7. PM2.5-pers(m-alt) two measurement-based approaches for estimating personal
exposures
1. PM2.5-pers(m) 8. PM2.5-pers(p) personal and predicted time-weighted indoor and outdoor
7. PM2.5-pers(m-alt) 8. PM2.5-pers(p) measured and predicted time-weighted indoor and outdoor
