Comments

"There is inadequate evidence in humans for the carcinogenicity of nitrilotriacetic acid and its salts." [IARC] NTA complexes of mercury, cadmium, and nickel degrade more slowly than complexes of lead, zinc, and iron; Undegraded NTA may accumulate in the environment; [HSDB] See "Nickel" and linked occupational diseases.
