2,4-Dintirotoluene is used as an intermediate in the manufacture
of polyurethanes. No information is available on the acute
(short-term) effects of 2,4-dinitrotoluene in humans. Chronic
(long-term) inhalation exposure to 2,4-dinitrotoluene affects the
central nervous system (CNS) and blood in humans. A significant
reduction in sperm count and normal sperm morphology was observed
in one study of chronically exposed workers, while other studies
have not reported this effect. No significant increase in cancer
mortality was observed in a study of workers occupationally
exposed to 2,4-dinitrotoluene by inhalation. Kidney, liver, and
mammary gland tumors were observed in animals orally exposed to
2,4-dinitrotoluene. EPA has not classified 2,4-dinitrotoluene
for potential carcinogenicity.
