The short sheet titled “IEUBK Model Soil/Dust Ingestion Rates” (OSWER 9285.7-33) dated December, 1999, discusses the earlier review of soil ingestion studies to determine if adjustments to the soil ingestion rates used in the IEUBK model are warranted. http://www.epa.gov/superfund/lead/products/ssircolo.pdf In 2006, the TRW reviewed the soil ingestion literature published since the short sheet was written to assess whether data from recent studies indicated changes to the soil ingestion rates were warranted. Based on its review, the TRW concluded that the recent literature did n
