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.

摘要： 对市售巴沙蚊香进行了系列毒性实验研究,证明蚊香含纯度为96%的巴沙原液3.3%。实验结果还表明:巴沙蚊香急性吸入毒性不大,亚急性吸入毒性未发现异常,小鼠骨髓细胞微核试验和Ames试验均为阴性,小鼠精子畸变作用不明显;蓄积试验结果:巴沙蚊香属弱蓄积性物质。以上实验结果提示:如巴沙原药的纯度确保在96%以上,其投药量控制在3.3%左右的巴沙蚊香,在实际使用中相对安全。
