The frequency of chromosomal aberrations in bone marrow cells, after a single i.p. aflatoxin B1 (AFB1) dose, was examined in male Chinese hamsters (Cricetulus griseus). There was a significant increase in aberrant cells within 5 days of administration of a dose of 0.1 micrograms-5 mg AFB1/kg, and on the 36th day. After a single dose of 5 mg AFB1/kg the enhanced frequency of aberrant cells was monitored up to day 104 with no sign of a decrease to control level. The results indicate that the minimum mutagenic effect of an AFB1 dose in this system is 0.1 micrograms/kg. Attention is drawn to the long-term presence of chromosomal aberrations even after a single i.p. exposure to AFB1.
