data is being read across from the source study that tested
Hydrocarbons, C10 aromatics based on analogue read across.
Twenty-five male rats and four dogs per
level were exposed for 6 hr/day, 5 days/wk for 13 wk. Another 20 rats,
from the same week of production, were maintained for use as challenge
exposure controls (naive rats). The challenge exposures were run to
determine whether the 6-hr daily inhalation of a non-lethal level of
hydrocarbon, would result in the rat becoming more or less resistant.
One rat at the 0.10-mg/liter level died
after 14 days. Death was attributed to a pneumonic infection as
evidenced by extensive lung abscesses. None of the observations were
dosage-related and are discounted for that reason. The test material’s
NOAEC > 0.38 mg/liter (66 ppm), which was the highest achievable vapor
