Analysis method of NDMA used in National Institute of Public Health in Japan

Place of stay: National Institute of Public Health, Japan

N-Nitrosodimethylamine (NDMA) is a member of a chemical class, N-Nitrosoamines, which are suspected carcinogens. In Japan, there are not so many laboratories that study NDMA and NDMA precursors. Yet among those laboratories including mine, the National Institute of Public Health has been conducting intensive study of NDMA. The members of National Institute of Public Health, who had been studying NDMA for four years, gave me a lot of help. They taught me, for example, pretreatment method of NDMA, measurement method of NDMA and NDMA precursors, and experimental method of monochloramine. Some of their experimental conditions were different from those used in my laboratory; this is because I focus on the NDMA concerned with sewage water, while the team at National Institute of Public Health focuses on the NDMA concerned with water purification and river water. It was, however, a good opportunity for me to get new experimental information and learn new measurement method of NDMA and NDMA precursors. Now I feel the necessity for a review of experimental and measurement methods that have been used in my laboratory.
