N-Nitrosodimethylamine. Biodegradation [PDF]

, 1984
Abstract : N-nitrosodimethylamine (NDMA) is biodegraded by microorganisms under certain conditions. In batch aqueous and soil studies the initial rates of mineralization increase with increasing concentration of NDMA, (ppt to ppm) however, the total percent or extent of mineralization decreases with increasing initial concentration.
