Trisodium nitrilotriacetate and algae book survey concerns the substance Trisodium nitrilotriacetate (in this report abbreviated as Na 3NTA), which is the most commonly used salt of the aminocarboxylic acid nitriloacetate (NTA).

In terms of toxicology and ecotoxicology it is NTA that determines the hazard of the substance. Other salts of NTA do exist (Disodium nitrilotriacetate (NA. TRISODIUM–NITRILOTRIACETATE (Na 3 NTA) The alternative sequestrant to NTA Resource Chemical Ltd.

Trisodium nitrilotriacetate (Na 3 NTA) was fed to two generations of rats either continuously or only during organogenesis (from days 6 to 15) in each pregnancy at one of two dietary levels, 01 or 05 %.

Four levels, 25, 25, or mg/kg/day, were administered by intubation to rabbits during organogenesis (on days 7–16) for one by: • trisodium nitrilotriacetate, ECis classified Carc. 2 and with a specific concentration limit of 5%.

Trisodium nitrilotriacetate was fed to dogs for 90 days atand % of the diet. No test-related changes were observed in general appearance, survival, hematology, serum chemistry, urinalysis or microscopic tissue examination.

No significant changes were observed between control and test groups in fecal cation excretion. The EU Risk Assessment Report for Trisodium Nitrilotriacetate () ("EURAR ") suggests that, in general, the Ca, Mg, and trace metal ions occurring in natural waters may actually complex with NTA salts, making the NTA salts unavailable biologically.

NTA is also cogenerated as an impurity in the synthesis of EDTA, arising from reactions of the ammonia coproduct. trisodium nitrilotriacetate (EU ) and a selection of primary literature. In this document, NTA is the abbreviation used for nitrilotriacetic acid, Na 2NTA for the disodium salt, Na 2NTA H 2O for the disodium salt monohydrate, Na 3NTA for the trisodium salt, and.

The incidences of renal tumors in rats treated with N-ethyl-N-hydroxyethylnitrosamine for 2 wk and t, 10, and 3, ppm trisodium nitrilotriacetate monohydrate for 30 wk were86 and 22%, respectively, while they were 16 and 0% in rats treated with N-ethyl-N-hydroxyethylnitrosamine or 30, ppm trisodium nitrilotracetate.

Trisodium nitrilotriacetate monohydrate was fed to male weanling Charles River rats for 28 days. Clinical evidence of urinary tract toxicity included hydronephrosis and nephromegaly. Microscopically, severe renal injury was recognized specifically as convoluted tubular cytoplasmic vacuolation and pelvic epithelial erosion.

The chronic toxicity of NTA (nitrilotriacetate) tested as the trisodium salt, to Daphnia magna in eight natural waters varied tenfold. A strong negative correlation (r = ) between water hardness and NTA toxicity was found; NTA was most toxic in water with a total hardness of 22 mg/liter and was least toxic in water with a total hardness of mg/liter.
