1972, Leo A. Orleans, Every Fifth Child: The Population of China, Stanford, CA: Stanford University Press, →ISBN, →LCCN, →OCLC, →OL, page 117:Surprisingly, this analysis revealed that acute exposure to solvent vapors at concentrations below those associated with long-term effects appears to increase the risk of a fatal automobile accident. Furthermore, this increase in risk is comparable to the risk of death from leukemia after long-term exposure to benzene, another solvent, which has the well-known property of causing this type of cancer.
