Research paper : Standardization of environmental analysis methods of hazardous chemicals (S. Taniyasu et al.)−286−Synthesiology - English edition Vol.5 No.4 (2013) readers can understand the process of “standardization.”6 Content of the standardizationComment (Akira Ono)In this paper, you describe how the international standard was created, but you do not describe details of the standard itself. Please describe what items were selected as “normative” and as “informative” respectively in the international standard. Also, please mention the reasons and background for those selections.Answer (Sachi Taniyasu)I have added the content of the standard and the background and process of the standardization, in addition to the response to comment 3 of discussion 3.7 Necessity of the standardization and the standardization processComment (Hiroaki Tao)In the international standardization, I think you should explain the role played by the Standard Certification R&D Project, as it may help the people who are trying for standardization using this system. This time, ISO standardization was first and JIS followed. I think if you explain this process and the problems in doing so, it will be helpful for people who are working on standardization by the reverse process.Answer (Sachi Taniyasu)I added the description of the work done in the Standard Certification R&D Project. As you indicated, in this research, the ISO standardization started before the JIS standardization. Also, for the ISO standardization of NP, Germany was investigating the standard for a similar analysis method, and it was necessary to do some preliminary adjustments with the convener country. Since such adjustments are important processes in standardization, I have added the description of this process. The points that were raised in the discussions in the process of ISO and JIS standardizations and the measures taken were described.8 Relationship between the public institutes and private companies in standardization (1)Question (Akira Ono)I think it is often the case in the environmental field, but there is a reality that private companies (or related industrial organizations) are not very interested in the development of standards. The reviewer thinks that the public research institute should take action in the fields that private companies are not interested (or cannot be interested), and that the general public expects the public research institute to take on such a role. Considering such a role of the public research institute, what is the opinion of the authors about the relationship of public research institutes and private companies in the standardization in the environmental field?Answer (Sachi Taniyasu)In the standardization in the environmental field that is closely related to the global issues, it is often difficult to obtain support from the industry sector. The authors think that the role to be played by the public research institute is great, as you indicated, and we have engaged in the standardization activities from this perspective. On the other hand, seeking solution technology for the environmental issues will help strengthen industrial competitiveness. Therefore, in the future, I think it is important to develop standardizations in close collaboration with industries, to contribute to the development of industry as well as to environmental preservation.9 Relationship between the public institutes and private companies in standardization (2)Comment (Hiroaki Tao)One of the reasons that it is difficult to obtain support from industry is because the development of an environmental analysis method may require new measures to prevent environmental pollution, or it may mean more expense for industry. However, recently, quick discovery of the solution to global issues is important in maintaining industrial competitiveness. The standardization to strengthen industrial competitiveness through advance acquisition of problem solving technology is a hope in gaining support from industry for the standardization of environmental analysis methods. I think you should emphasize this point.Answer (Sachi Taniyasu)As indicated, it was difficult to gain support from the industrial organizations due to the image that new measures may be needed after standardization. However, taking measures quickly before something becomes a major social issue will encourage seeking a solution for an environmental issue, and this will lead to strengthening of the industrial competitiveness and the healthy growth of industry in the long run. Therefore, I suggested that the standardization in collaboration with industry is necessary in the future.10 Effect of standardizationComment (Akira Ono)The question “How are these international standards being utilized?” in the beginning of chapter 5 is important. That’s because the important objective should not be making a standard, but how the standard is used.It is important to investigate what aspects of society changed after the standards were delivered and used in the international community, and to compare the actual effect it brought about and the expected effect that was supposed to happen. Please address what were the actual effects in the society after the standards were enforced.Answer (Sachi Taniyasu)For the NP standards, two ISO standards were proposed by Germany and one was proposed by Japan. The first standard proposed by Germany (ISO 18857-1) is of total NP measurement, and the measurements of the individual isomers of NP were not described. However, in the Japanese proposed standard (ISO 24293), the necessity of analysis for individual isomers was widely recognized internationally, and the reagent manufacturers started the sales of reference standards for different isomers. The second Germany-proposed standard (ISO 18857-2) was also of total measurement of NP as in Part 1, but because the standards for individual isomers have become available and also because of the importance of the analysis for individual isomers, the measurements for different isomers were added and this enabled more detailed risk assessment using the analysis method. Most private analytical laboratories that subcontract the PFOS/PFOA analysis are in compliance with ISO 25101 and JIS K 0450-70-10, and this enables the provision of high quality and mutually comparable data. I think progresses have been made through this standardization.
