Industrial Land Use
Sensitive Receptor:
Exposure Period:
adult
10 hours/day
5 days/week
48 weeks/year
Direct Soil Exposure Pathways:
• direct soil ingestion
• direct soil dermal contact
• direct soil particulate inhalation
Indirect Soil Exposure Pathways:
• groundwater as drinking water
• infiltration of volatile contaminants into indoor air via basements
The above check mechanisms are calculated. If check modelling procedures indicate an
unacceptable exposure, the soil quality guideline is lowered.
• off-site migration of soil contaminants via wind and water erosion
• This check mechanism can result in the lowering of the final SQC HH via a management
adjustment factor.
