GefahrenübersichtThere 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 ironUndegraded NTA may accumulate in the environment[HSDB] See Copper.
OSHA StandardsPermissible Exposure Limit: Table Z-1 8-hr Time Weighted Avg: 1 mg/cu m. /Copper dusts and mists (as Cu)/
NIOSH RecommendationsRecommended Exposure Limit: 10 Hr Time-Weighted Avg: 1 mg/cu m. /Copper (dusts and mists)/
Clean Water Act AnforderungenToxic pollutant designated pursuant to section 307(a)(1) of the Federal Water Pollution Control Act and is subject to effluent limitations. /Copper and cmpd/
Landesrichtlinien für Trinkwasser(AZ) ARIZONA 1300 ug/l /Copper/
Federal Drinking Water StandardsEPA 1300 ug/l (Action Level) /Copper/
Bundesrichtlinien für TrinkwasserEPA 1000 ug/l /Copper/
Expositionsschutz und Persönliche Schutzausrüstung0.01 [mg/m3], respirable fraction (Cu, inorganic cmpnds)[German Research Foundation (DFG)]
EntsorgungsverfahrenSRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
Threshold Limit Values (TLV)1.0 [mg/m3], as Cu8 hr Time Weighted Avg (TWA): 1 mg/cu m /Copper dusts and mists, as Cu/Excursion Limit Recommendation: Excursions in worker exposure levels may exceed 3 times the TLV-TWA for no more than a total of 30 minutes during a work day, and under no circumstances should they exceed 5 times the TLV-TWA, provided that the TLV-TWA is not exceeded. /Copper dusts and mists, as Cu/
Permissible Exposure Limit (PEL)1.0 [mg/m3], as Cu
Immediately Dangerous to Life or Health (IDLH)
100.0 [mg/m3], as Cu
Unerwünschte WirkungenOccupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation.
Environmental BiodegradationA NITRILOTRIACETATE (NTA)-DEGRADING PSEUDOMONAS SPECIES WAS SHOWN TO DEGRADE CA, MN, MG, CU, ZN, CD, FE, & NA CHELATES OF NTA @ NEARLY EQUAL RATES WHEN THE APPROPRIATE METAL CONCN ARE LOW ENOUGH TO AVOID TOXICITY FROM THE FREED METAL.
Non-Human Toxicity ExcerptsTOXICITIES OF CU CHELATES WITH NTA & EDTA WERE 1-3 FOLD LESS THAN THAT OF UNCHELATED CU ION.
Evidence for CarcinogenicityEvaluation: 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/
