Dose Response Assessment Tables

The information below presents tabulated dose-response assessments that the Office of Air Quality Planning and Standards (OAQPS) uses for risk assessments of hazardous air pollutants. Two separate tables are provided. Table 1 presents values for long-term (chronic) inhalation and oral exposures; Table 2 presents values for short-term (acute) inhalation exposures. It is important to note that only for the purpose of these tables that the compound categories use the CAS number for the element. However, all compounds having that element in their chemical structure are included in the compound category.
