  • First Aid: EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknow Source: CAMEO Chemicals

  • Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for N-nitrosodiethanolamine(SRC), using an estimated log Kow of -1.28(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that N-nitrosodiethanolamine is expected to have very high mobility in soil(SRC). Volatilization of N-nitrosodiethanolamine from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 4.9X10-12 atm-cu m/mole(SRC), using a fragment constant estimation method(2). N-Nitrosodiethanolamine is not expected to volatilize from dry soil surfaces based on an estimated vapor pressure of 5.0X10-4 mm Hg at 20 °C(3). N-Nitrosodiethanolamine has a UV absorption max at 345 nm(4) which indicates that the compound may be susceptible to direct photolysis by sunlight(SRC). Biodegradation in soil may be slow(SRC), based upon N-nitrosodiethanolamine's slow biodegradation in two lake waters and sewage(5). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that N-nitrosodiethanolamine is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 4.9X10-12 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). According to a classification scheme(4), an estimated BCF of 3(SRC), from an estimated log Kow of -1.28(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low. The direct photolysis rate constant for the analogous compound N-nitrosodiethylamine in aqueous solution exposed to irradiation representing Southern California midsummer, midday sun was observed to be 0.045/min with a half-life of 15 minutes and a quantum yield of 0.43(5); the photolysis rate of N-Nitrosodiethanolamine is expected to be similar(SRC). N-Nitrosodiethanolamine biodegraded slowly in samples of sewage and two lake waters(6). The fastest degradation of N-nitrosodiethanolamine in a lake water sample was in one taken in August; an initia Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), N-nitrosodiethanolamine, which has an estimated vapor pressure of 5.0X10-4 mm Hg at 20 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase N-nitrosodiethanolamine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 13 hours(SRC), calculated from its rate constant of 3X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). N-Nitrosodiethanolamine has a UV absorption max at 345 nm(4) which indicates that N-Nitrosodiethanolamine may be susceptible to direct photolysis by sunlight(SRC).
