National Cancer Institute carcinogenesis technical report series, 11, 1-88 (1977-01-01)
A bioassay of the chelating agent, trisodium ethylenediaminetetraacetate trihydrate (Na3EDTA.3H2O), for possible carcinogenicity was conducted by administering the test material in feed to Fischer 344 rats and B6C3F1 mice. The chemical was administered to 50 males and 50 females of
