Pesticides have been checked for the presence of N-dimethyl-nitrosamine, N-diethylnitrosamine, N-dipropylnitrosamine, N-diisopropylnitrosamine and N-dibutylnitrosamine. Quantitation was accomplished by GC-MS operated in the E.I. mode with selected ion monitoring of the nitrosamines. Trifluralin was found to contain 34 ppm of N-dipropylnitrosamine. No nitrosamines were detected in the other pesticides analyzed.
