Study of respiratory response of guinea pigs to oil mists

Journal Article · · Am. Ind. Hyg. Assoc. J.; (United States)
A study of respiratory response of guinea pigs to oil mists, including mists of laboratory-grade paraffin oil, light lubricating oil (neat and saturated with SO/sub 2/), an unused multigrade additive motor oil (neat and SO/sub 2/-saturated), and a used motor oil (neat and SO/sub 2/-saturated) supplied at 10, 40, 100, and 200 mg/cu m for one hour, showed that aerosols of these oils at < 200 mg/cu m are not short-term irritants, as monitored by pulmonary functions, and that there is no apparent relationship between pulmonary mechanics and the hydrocarbon structure, the presence of additives or combustion products, or saturation with sulfur dioxide. At >200 mg/cu m, both the reacted and unreacted light lubricating oil mists significantly reduced lung compliance. With the exception of the reacted light lubricating oil and the reacted used motor oil, all the exposures produced a slight increase in respiratory frequency, which appeared related to the stress of the exposure.
