The download tables do not include the ingestion of fish exposure pathway, the outdoor worker and the indoor worker exposure to soil exposure pathway that are presented in the User's Guide. The tables contain both SL calculations and the toxicity values that were used. These tables are considered ready for use. Use the tables appropriate for your region.
All tables are presented with target cancer risk (TR) of 1E-06, however, tables are presented with target hazard quotients (THQ) of 1.0 and 0.1.
