Abstract:

Chronic exposure to Galosha naphtha vapor in a concentration of 106.5 mg cu m for 5 months for 6 hours a day causes functional changes of the conditioned reflexive activity in experimental animals that build in proportion to exposure and appear two weeks after terminating exposure. The reflex action of Galosha naphtha vapor on light sensitivity of the eye is only observed at a concentration of 56 mgcum or higher. The most sensitive indicator for establishing the maximum permissible concentration of gasoline vapor in atmospheric air is the threshold of odor. Taking into account the need for a certain reserve factor and the slight difference in the threshold of odor for the investigated types of gasoline, one can recommend 5 mgcu m in recalulation for carbon as the maximum single permissible concentration for the types of low sulfur petroleum gasoline.
