Mercury(2+) NTA

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 Mercury, inorganic compounds and the linked occupational disease.

D009; A solid waste containing mercury may or may not become characterized as a hazardous waste when subjected to the Toxicity Characteristic Leaching Procedure listed in 40 CFR 261.24, and if so characterized, must be managed as a hazardous waste. /Mercury/

Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Mercury (2+) NTA is included on this list.

D009; Mercury. A waste containing mercury may or may not be characterized as a hazardous waste following testing by the Toxicity Characteristic Leaching Procedure as prescribed by the Resource Conservation and Recovery Act (RCRA) regulations. /Mercury/

Recommended Exposure Limit: 10 Hr Time-Weighted Avg: 0.01 mg/cu m. /Mercury (organo) alkyl compounds (as Hg)/
