2,4-D is a herbicide used on a number of crops. At high
concentrations it affects the central nervous system (CNS) in
humans, with symptoms including stiffness of arms and legs,
incoordination, lethargy, anorexia, stupor, and coma. 2,4-D is
also an irritant to the gastrointestinal tract and skin in
humans. Chronic (long-term) oral exposure to 2,4-D results in
effects on the blood, liver, and kidneys in animals. Several
human studies have suggested an association between exposure to
2,4-D (and other herbicides) and an increased incidence of tumor
formation. However, it is not clear whether this represents a
true association, and, if so, whether it is specifically related
to 2,4-D. Some studies have reported increased incidences of
tumors in orally exposed animals. EPA has not classified 2,4-D
as to its human carcinogenicity.
