Contamination of indoor air by toxic soil vapours: a screening risk assessment model
journal contribution

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).
