Research paper : Standardization of environmental analysis methods of hazardous chemicals (S. Taniyasu et al.)−284−Synthesiology - English edition Vol.5 No.4 (2013) AuthorsSachi TaniyasuCompleted the doctor’s course at the Graduate School of Natural Science and Technology, Kanazawa University in March 2006. Joined the Potential Pollutants Group, Research Institute for Environmental Management Technology, AIST in April 2006. Engages in the development of the analysis method for persistent organic halogen compounds and the research on the environmental fate. In this paper, was in charge of the development of analysis method, ISO standardization, and JIS standardization of PFOS and PFOA.Nobuyasu HanariCompleted the doctor’s course in Agricultural Technology and Sciences at the Graduate School of Life and Environmental Sciences, University of Tsukuba in March 2001. Joined the Potential Pollutants Group, Research Institute for Environmental Management Technology, AIST in July 2004, and engaged in the development of the analysis method for dioxin analogs. Transferred to the Organic Analytical Chemistry Division, National Metrology Institute of Japan in October 2005. Engaged in the development of the national standard (NMIJ CRM) of organic reference material (particularly for persistent organic pollutants). Developed the reference materials essential for the operation of JCSS to ensure traceability, as well as general CRM. In this paper, was in charge of the development of potassium perfluorooctanesulfonate reference liquid (NMIJ CRM 4220-a).Yuichi HoriiCompleted the doctor’s course at the Graduate School of Science and Engineering, Ibaraki University in March 2006. Post-doctorate researcher at the New York State Department of Health (Wadsworth Center) for two years from May 2006. Joined the Center for Environmental Science in Saitama in October 2008, and engages in the environmental monitoring and fate study of persistent organic pollutants. Current interest is the natural production of dioxin in kaolin clay. In this research, was in charge of the development of the analysis method for individual NP isomers.Nobuyoshi YamashitaCompleted the doctor’s course in Environmental Chemistry at the United Graduate School of Agricultural Sciences, Ehime University in 1992. Joined the National Institute for Resources and Environment, Agency for Industrial Science and Technology (current AIST) in 1992. Has been involved in the development of new technologies and their applications in the environmental analytic chemistry field. Has supervised various tests and researches on international E.
