Abstract: Octachlorodipropylether(S₂) is a super synergist of synthetic pyrethroid.It has found favour in common people's eyes because of its lower cost and high effectivenes, withoat any tcxicity reported in S₂' mosquito-repcllent incense. In order to ensure safety and provide requisite scientific basic for opplication,we have studied S₂ and S₂' mosquito-repellent about the toxicity and the toxicology. The result shows S₂ belongs to lower toxicity substance and mntagenicity test is nagatire.The method of the gaseous state and the inhalation exposure has been taken in toxicity test of S₂' mosquito-repllent, and nodrug mosquito-repellent for control. S₂' mosquitc-repllentbelongs to lower toxicity substance too,but Ames test showed positive reaction among TA₉₈+S₉2.0 and 4.0mg/L concentrations, TA_{100-S9,1.0,2.0,4.0 and 3.0mg/L concentrations, TA100+S9 4.0 and 8.0mg/L concentrations.Assay of mouse DNA synthesis and inhibition, 2.73mg/L concentration group has n influence over DNA synthesis of mouse lungs and testicular cell. Acoumulation coefficient K>8, S2mosquito is part of weak accumulation material,and unusual change is not found in subscute toxicity test.}
