Figure 10.

Figure 10 is an error bar graph titled Naphthalene Inhalation Exposures: Summary of Lowest Observed Adverse Effect Levels. Exposure concentration (milligram per square meter) ranging from 0.1 to 1 in increments of 0.1, 1 to 10 in increments of 1, 10 to 100 in increments of 10, and 100 to 1000 in increments of 100 are plotted on the y-axis. Exposure durations and health systems are plotted on the x-axis, including acute (less than 24 hours) respiratory; short-term (1 to 30 days) hematologic and respiratory; subchronic (30 to 90 days) immune, reproductive, and respiratory; and chronic (greater than 90 days) respiratory. The plot shows the dose ranges tested and the minimum lowest observed adverse effect level for each exposure duration and health system.

Summary of the dose ranges and lowest LOAELs within each health system across high and medium confidence animal inhalation exposure studies. Open circles represent the doses tested across all studies that reported a LOAEL for each health system. Note: LOAEL, lowest observed adverse effect level.
