| WHO and 2,4D
Note that this report acknowledges the risk being related to the 2,4,5-T being contaminated with dioxin. Taken out of context, the first line says that studies have suggested a link. The next sentence says that the study did not test the effects of just 2,4-D. There may be other papers where the WHO addresses only 2,4-D.

Toxicological review
Epidemiological studies have suggested an association between exposure to
chlorophenoxy herbicides, including 2,4-D, and two forms of cancer in humans: softtissue
sarcomas and non-Hodgkin lymphoma. The results of these studies, however,
are inconsistent; the associations found are weak, and conflicting conclusions have
been reached by the investigators.Most of the studies did not provide information on
exposure specifically to 2,4-D, and the risk was related to the general category of
chlorophenoxy herbicides, a group that includes 2,4,5-trichlorophenoxyacetic acid
(2,4,5-T), which was potentially contaminated with dioxins. JMPR concluded that it
was not possible to evaluate the carcinogenic potential of 2,4-D on the basis of the
available epidemiological studies. JMPR has also concluded that 2,4-D and its salts
and esters are not genotoxic. The toxicity of the salts and esters of 2,4-D is comparable
to that of the acid. | |
