Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal and plant life; and conformance with environmental and public health regulations.

Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

The development of renal tumors was examined in rats given 1000 ppm N-ethyl-N-hydroxyethylnitrosamine (NEELA) and then 30,000, 10,000 or 3,000 ppm of trisodium nitrilotriacetate monohydrate (Na3 X NTA X H20) in their food. The incidences of renal tumors in rats treated with N-ethyl-N-hydroxyethylnitrosamine for 2 wk and then 30,000, 10,000 and 3,000 ppm trisodium nitrilotriacetate monohydrate for 30 wk were 100, 86 and 22%, respectively, while they were 16 and 0% in rats treated with N-ethyl-N-hydroxyethylnitrosamine or 30,000 ppm trisodium nitrilotracetate monohydrate at 30,000 or 10,000, but not 3,000 ppm, also incr the size and number of renal tumors in rats treated with N-ethyl-N-hydroxyethylnitrosamine and trisodium nitrilotriacetate monohydrate 30,000 ppm, but not 10,000 or 3,000 ppm also induced hydronephrosis in rats irrespective of whether they were treated with N-ethyl-N-hydroxyethylnitrosamine. Thus, trisodium nitrilotriacetate monohydrate has a dose-related effect on the kidney. /Trisodium nitrilotriacetate monohydrate/

ORAL ADMIN OF TRISODIUM NITRILOTRIACETATE (0.01, 0.10, OR 1% WT/VOL IN DRINKING WATER) DID NOT ENHANCE THE PATHOLOGICAL EFFECTS OF LEAD ON THE RAT RENAL SYSTEM; HOWEVER, RATS GIVEN 0.01 OR 0.10% WITH OR WITHOUT LEAD WERE HYPERGLYCEMIC.

The effects of the renal tumor promoters; beta-cyclodextrin, DL-serine, basic lead acetate, trisodium nitrilotriacetate monohydrate & potassium bromate, & diethylene glycol as a negative control, on early stage of renal carcinogenesis were investigated in unilaterally nephrectomized male Wistar rats after N-ethyl-N-hydroxyethylnitrosamine admin. Wistar male rats were fed 1000 ppm N-ethyl-N-hydroxyethylnitrosamine diet for 2 wk & the left kidney was removed at week 3, then the animals were divided into 7 groups of 15 rats each. These groups received the following treatments: 1000 ppm lead acetate, 10000 ppm trisodium nitrilotriacetatemonohydrate or 500 ppm potassium bromate diet for 18 wk from wk 3; 45 mg/100 g bw/day of beta-cyclodextrin injected sc for 7 days; 100 mg/100 g bw of DL-Serine injected sc biweekly for 6 weeks; 5% diethylene glycol in drinking water as a negative control for two days. Five rats in each group were killed at wk 8, 12 & 20 & their kidneys were examined histologically. At wk 20, the avg numbers of adenomatous hyperplasias seen as preneoplastic lesions in the beta-C, DL-Serine, lead acetate, trisodium nitrilotriacetate monohydrate or potassium bromate groups were significantly higher than those in the diethylene glycol or control groups. Thus within a relatively short period of 20 wk, promoting effects of chemicals can be detected as a significant incr of adenomatous hyperplasias in this model. /Trisodium nitrilotriacetate monohydrate/

The dose-dependent effect of trisodium nitrilotriacetate monohydrate as a promoter in two stage carcinogenesis in the urinary bladder of male Wistar rats was investigated. Carcinogenesis was initiated by administration of 0.05% N-butyl-N-(4-hydroxybutyl)nitrosamine in the drinking water for 4 weeks, then trisodium nitrilotriacetate monohydrate was given at 1%, 0.5% and 0.3% in the diet for 28 weeks, and rats were killed in week 32. The incidences and numbers of preneoplastic lesions (papillary or nodular hyperplasia, PN hyperplasia) in rats treated with 0.3% to 1% trisodium nitrilotriacetate monohydrate increased progressively with increasing concentration of trisodium nitrilotriacetate monohydrate. The incidences of papillomas in rats treated with 1% and 0.5% trisodium nitrilotriacetate monohydrate in the diet and the incidence of transitional cell carcinoma of the urinary bladder in the rats treated with 1% trisodium nitrilotriacetate monohydrate (P< 0.05) were significantly higher than those in rats treated with N-butyl-N-(4-hydroxybutyl)nitrosamine only. Administration of various doses of trisodium nitrilotriacetate monohydrate without N-butyl-N-(-hydroxybutyl)nitrosamine did not cause any histological changes (papillary or nodular hyperplasia, papilloma or transitional cell carcinoma) in the urinary bladder. These findings showed that trisodium nitrilotriacetate monohydrate is a potent promoter of urinary bladder carcinogenesis initiated by N-butyl-N-(4-hydroxybutyl)nitrosamine in rats, and that its effect is dose-dependent. /Trisodium nitrilotriacetate monohydrate/

Trisodium nitrilotriacetate is readily decomp by soil microorganisms under anaerobic or aerobic conditions. Nitrilotriacetate-N converted to nitrate under aerobic conditions, indicating use of detergents containing nitrilotriacetate leading to nitrate enrichment of water resources.

A nitrilotriacetate (NTA)-degrading pseudomonas species was shown to degrade Ca, Mn, Mg, Cu, Zn, Cd, Fe and Na chelates of nitrilotriacetate at nearly equal rates when the appropriate metal concn are low enough to avoid toxicity from the freed metal

In an aerated sewage lagoon, trisodium nitrilotriacetate breakdown was temperature dependent: 93% at 15 °C; 47% at 5 °C; and 22% at 0.5 °C.

Evaluation: There is inadequate evidence in humans for the carcinogenicity of nitrilotriacetic acid and its salts. There is sufficient evidence in experimental animals for the carcinogenicity of nitrilotriacetic acid and its sodium salts. Overall evaluation: Nitrilotriacetic acid and its salts are possibly carcinogenic in humans (Group 2B). /Nitrilotriacetic acid and its salts/

As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their continued use. Under this pesticide reregistration program, EPA examines newer health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether the use of the pesticide does not pose unreasonable risk in accordance to newer saftey standards, such as those described in the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA '88 were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern than those on List C, and with List C containing pesticides of greater concern than those on List D. Nitrilotriacetic acid, trisodium salt is found on List D. Case No: 4014; Pesticide type: Antimicrobial; Case Status: OPP is reviewing data from the pesticide's producers regarding its human health and/or environmental effects, or OPP is determining the pesticide's eligibility for reregistration and developing the Reregistration Eligibility Decision (RED) document.; Active ingredient (AI): Nitrilotriacetic acid, trisodium salt; AI Status: The producers of the pesticide have made commitments to conduct the studies and pay the fees required for reregistration, and are meeting those commitments in a timely manner.
