Kerosene absorption in primates.

Kerosene, labeled with 3H-toluene or 14C-hexadecane, was given to baboons by nasogastric tube after a tracheostomy had been performed. Six hours later the animals were killed and samples of tissues taken for analysis. The radioactive label was recovered from all the tissues analyzed. 3H-toluene appeared to be absorbed and taken up by most tissues to a greater extent than was 14C-hexadecane. No abnormal neurologic signs or behavior was noted in the baboons which were conscious during the study period. It appears that primates absorb kerosene from the gastrointestinal tract, but the volumes are very small and do not cause gross neurologic signs.
