established on the basis of the blood lead model, on the basis of the blood lead goal of <10 µg/dL for all routes of exposure and all sources.

The most commonly used (and recommended) blood lead model relevant to the most sensitive age group, infants and young children, is the IEUBK model (win 32, Model 1.1). On the basis of the assumptions presented in Appendix C (consistent with the pathway-specific assumptions outlined in this review and reviewed in line with the use of the IEUBK model in Port Pirie (South Australia)), HIL A = 306 mg/kg. A value of around 300 mg/kg can also be confirmed using the model LeadSpread available from the California Department of Toxic Substances Control.

    8.5.1         HILs
On the basis of the above, the previous soil HIL of 300 mg/kg for lead has been reaffirmed. HILs B, C and D have also been reaffirmed on the basis of the blood lead model.
HIL Scenario    HIL (mg/kg)
Residential A   300
Residential B   1200
Recreational C  600
Commercial D    1500
