Figure 2.

Figure 2 is a graph titled Naphthalene Oral Reference Values, plotting dose rate (milligrams per kilogram per day), ranging from 0.000001 to 0.00001 in increments of 0.000001; 0.00001 to 0.0001 in increments of 0.00001; 0.0001 to 0.001 in increments of 0.0001; 0.001 to 0.01 in increments of 0.001; 0.01 to 0.1 in increments of 0.01; 0.1 to 1 in increments of 0.1; and 1 to 10 in increments of 1 (y-axis) across duration (days) ranging from 0 to 1 in increments of 0.1; 1 to 10 in increments of 1, 10 to 100 in increments of 10; 100 to 1000 in increments of 100; 1000 to 10000 in increments of 1000; 10000 to 100000 in increments of 10000; and 100000 to 1000000 in increments of 100000 (x-axis) for acute for 24 hours, short term for 30 days, subchronic for 7 years, and chronic for 70 years. The health effect reference values for oral exposure to naphthalene are as follows: Agency for toxic substances and disease registry minimal risk level, E P A or Integrated risk information system reference dose, E P A or office of pesticide programs reference dose, Rijksinstituut voor Volksgezondheid en Milieu tolerable daily intake, and California environmental protection agency’s office of environmental health hazard assessment cancer risk range.

Available health effect reference values for oral exposure to naphthalene. See Supplemental Materials Appendix Table A2 for a tabular summary, including information on how each value was derived. All values in this figure are intended for application in the general public. Note: ATSDR, Agency for Toxic Substances and Disease Registry; IRIS, Integrated Risk Information System; MRL, minimal risk level; OPP, Office of Pesticide Programs; RfD, reference dose; RIVM, Rijksinstituut voor Volksgezondheid en Milieu (Netherlands Institute for Public Health and the Environment); TDI, tolerable daily intake.
