|Abstract: ||A simple steady-state model is derived for estimating the concentration of vapourphase
contaminants in indoor air, given the contaminant concentration in the soil.
The model includes the key mechanisms of transport and dispersion - contaminant
partitioning into the soil-vapour phase, molecular diffusion, suction flow, and
ventilation rate. It is shown that indoor air concentrations are largely controlled
by two variables: soil permeability, and the half-life for contaminant removal
from soil. A worked example shows the effect of these two variables on the
concentration of benzene in soil that would give rise to a concentration of benzene
in indoor air of 5 ppb (the recently proposed UK Air Quality Standard).|
