N‐nitrosamines and mutagens in rubber nursing nipples

Abstract
Aqueous extracts of 4 brands (8 types) of rubber nursing nipples purchased in the open market were analyzed for volatile N-nitrosamines, diphenylamine and mutagenic activity. N-Nitrosodimethylamine, N-nitrosodiethylamine, or N-nitrosopiperidine were found in the aqueous extracts of the nipples and in the nipples themselves. All nipples analyzed contained one or more of the 3 volatile N-nitrosamines. Diphenylamine was found to be continously released into aqueous extracts from most brands. Certain nipples produced a positive mutagenic response when incubated with Salmonella typhimurium (TA 100) in a modified liquid suspension test. [This could afect human infants.].
