6. "In evaluating indoor air concentrations of carcinogenic or toxic compounds, some confusion exists over the various units in use. Common units of indoor air measurements include ug/m3 or mg/m3, ug/L or mg/L, ppbV and ppmV. The confusion arises in converting from mass-per-volume to parts-per- number-volume units. It is important to remember that ug/L in gas systems IS NOT equal to ppbV, nor is mg/L in gas systems equal to ppmV. Each of these conversions is dependent upon the molecular...
