Appendix JChemical-Specific Inputs for CCW Constituent ScreeningAppendix J. Chemical-Specific Inputs Used inCCW Constituent ScreeningChemical-specific inputs used to develop the CCW HBNs include the bioconcentrationfactors needed to estimate exposure concentrations in fish. Values for these inputs are obtainedfrom the best available literature source. Table J-1 provides, for each chemical in the CCWscreening analysis, the values used in the analysis along with the source of each value.Parameter aAluminum (7429905)No DataAntimony (7440360)Table J-1.
