Dimethylamine was found to be nitrosated photochemically in aqueous solution containing nitrite both by the irradiation with a high pressure mercury lamp and by the exposure to sunlight to give nitrosodimethylamine, a well-known carcinogen. The nitrosation occurred more readily at alkaline pH than at acidic and neutral pH. These findings suggest that nitrosodimethylamine is produced photochemically under natural environmental conditions.
