Abstract: The article deals with a series of toxic study of Bassa mosquito-repellent incense sold in the market. The incense contains 3.3% of raw Bassa jnice of which the purity is 96% Experimental results showed that the acute inhaling toxicity of the incense was not severe and nothing abnormal was found in subacute inhaling toxicity. Both the micronucleas test with spinal cord of mice and Ames test are negative, Sperm malformation of mice is not apparent. The results of accumulated experiments indicate that Bassa incense belongs to the weak accumulating substance. All results of this study suggest that if the purity of raw Bassa is ensured to be over 96% and the given dosage is to be controlled under'3.3%, the incense is relatively safe in practical utilization.
