Urinary excretion of N-nitrosodiethanolamine administered orally to rats. 1978

R Preussmann, and G Würtele, and G Eisenbrand, and B Spiegelhalder

N-Nitrosodiethanolamine (NDE1A) was administered by gavage to male rats in single doses of 1000, 500 and 100 mg/kg body wt. More than 70% of a given dose was excreted unchanged in the urine, essentially within the first 24 h after exposure. This high excretion rate might explain the relatively low carcinogenic potential of NDE1A, and also offers a possible method of monitoring exposure to this compound under occupational and/or environmental conditions.
