Screening Levels, 2010) indicates that based on consideration of the same pathways of exposure (soil ingestion, dermal contact and inhalation of particulates), health-based guidelines for non-carcinogenic PAHs are at least 10,000 times higher than the BaP guideline. Hence the adoption of a factor of 100 as an additive total for other non-carcinogenic PAHs is considered reasonable.
    * The HILs for total PAHs are only relevant provided carcinogenic PAHs meet the BaP HILs and naphthalene also meets the relevant HSLs.
On the basis of the above, the following HILs are recommended for total PAHs (provided carcinogenic PAHs meet the BAP HIL and naphthalene meets the relevant HSL):

HIL Scenario    HIL (mg/kg)
Residential A   300
Residential B   400
Recreational C  300
Commercial D    4000
