N ‐Nitrosodimethylamine was not degraded in flooded soil or in microbial enrichments from bog sediments. Enrichment cultures inoculated with soil and sewage did not yield microorganisms capable of metabolizing N ‐nitrosodimethylamine, N ‐nitrosodiethylamine, or N ‐nitrosodi‐ n ‐propylamine. N ‐Nitrosodimethylamine was not metabolized by axenic cultures of bacteria, and it was not significantly inhibitory to individual bacterial cultures or to respiration of soil or sewage communities. The data suggest that the nitrosamines persist in samples of natural environments because of the resistance of the nitrogen‐nitrogen bond in nitrosamines.
