Indoor PM Concentrations in Inner-City Baltimore Homes

These box and whisker plots demonstrate the PM values measured in the homes and simultaneous ambient levels. The boxes show the interquartile ranges (IQR) and the heavy dark lines are the medians. Whiskers represent closest value within1.5X the IQR of PM values. In-home PM concentrations were significantly higher than ambient PM concentrations and in most cases. Over 75% of homes exceeded the EPA annual limit for ambient PM2.5 and 47% of homes exceeded the annual limit for PM10.
