| Research Abstract |
Conversion yields of six compounds to N-nitrosodimethylamine (NDMA) by ozonation were investigated. It was found that the compounds with the function, (CH_3)_2N-N, had high conversion yields to NDMA by ozonation and the surrounding structures of the function were related to NDMA formation. It was considered that the conversion yields of some compounds were not affected by co-existing compounds or radicals, but others were affected. The compounds with high conversion yields to NDMA by ozonation were different from those by chloramination.
