Research paper : Standardization of environmental analysis methods of hazardous chemicals (S. Taniyasu et al.)−285−Synthesiology - English edition Vol.5 No.4 (2013) Discussions with Reviewers1 Overall evaluationComment (Akira Ono, AIST)This paper is based on the authors’ excellent research results on the analysis technology for hazardous chemical substances in the environment, and the effort was brought to international standardization through international joint collaboration. It can be seen that the synthetic and integrated researches were conducted based on a clear scenario that aims for international standardization, and this research is appropriate as a paper to be published in Synthesiology.It should be noted that in this paper the authors conducted the research and standardization as a set. These standards have been used widely by people in the society after the international standard was published, and that should also be highly evaluated.2 Expressions in consideration of the general readersComment (Akira Ono)It is hoped that the papers of Synthesiology are read not only by specialists of certain technological fields, but also by researchers and engineers of wide-ranging fields. I think the intents of this paper are to introduce the thinking on international standardization, to present some case studies of environmental analysis to a wide range of readers, and to widely share this information.From this perspective, I see some expressions that may be hard to understand for people whose specialties are not analytical chemistry, so please work on the written expression to ensure better communication.Answer (Sachi Taniyasu)As you indicated, there are many terminologies and expressions that may be hard to understand for the researchers and engineers outside the environmental analysis technology specialty, and I also realize that this may prevent understanding of the reader. I have added descriptions to the text and added explanations in “Terminology” to enhance the understanding of the standardization process in this research.3 Composition of the paper (1)Comment (Akira Ono)Synthesiology requires the paper to have the following composition, so please consider revising.(1)First, how the research goal is linked to “social values” is explained,(2)next, the “research scenario” showing how the authors achieve the research goal is drawn, and then(3)the “synthesis process” of how elemental technologies were integrated to achieve the research goal is described.I think the readers will have better understanding if you summarize the “research scenario” of (2) into a diagram that gives an overview of the entire research. The reviewer suggests a diagram of the “research scenario” within his understanding of this paper, so please consider it as a reference if it is useful.Answer (Sachi Taniyasu)(1)The research goal of this paper is the “standardization of the quality control to improve the reliability of analytical chemistry technologies both in Japan and overseas, as well as being various standardizing committee member and TC147/SC2/WG56 convener. Also contributed to the councils of chemical substance management policy such as the member of New POPs Review Committee. Highly Cited Author Award in 2010 (2 articles). Was the supervisor of this research.analysis method.” Therefore, the main objective is to explain the four cases where the international and domestic standards such as ISO and JIS were established using the technological ideas developed by AIST. The chemical substances studied in this research began to be recognized as environmentally hazardous chemical substances when this research started. However, there was no analysis method for which reliability was assured, and it was difficult to understand the environmental load of the chemicals that was important in taking appropriate environmental measures. The need for standardization of the analysis method in such environmental analysis and the social background of the subject compounds were described specifically in chapters 1 and 2. The ISO and JIS systems for environmental analysis and the positioning of this report were described, and texts were added to enhance the understanding of this research.(2)In achieving the standardization, unlike the flow of “industrial demand development of analysis method quality control JIS standardization ISO standardization” that is commonly seen in ordinary standardization, the research was conducted in the flow of “understanding the environmental behavior and environmental loadings necessary to manage the chemical substances development of analysis method quality control industrial demand JIS standardization.” Based on the diagram that you provided for us, we created Fig. 4 as the scenario of this research.(3)Details were described about the problems that were discussed in the process of ISO and JIS standardizations and the measures that were taken to solve them. Also, we added some points which were determined to be the normative items (rules to comply) and informative items (information provided for reference).4 Composition of the paper (2)Comment (Hiroaki Tao, Research Institute for Environmental Management Technology, AIST)The composition of this paper is introduction, development of the analysis method, standardization, contribution to chemical substance management, and conclusion. I think the part on the clarification of environmental behavior is lacking. The reason this standardization was successful was because you published the paper on the clarification of environmental behavior and were highly evaluated internationally for conducting such excellent research. Therefore, I think you should add a chapter on the subject of clarification of environmental behavior.Answer (Sachi Taniyasu)I have added the text on the discussion of the environmental behavior, in the process of explaining the research elements and scenario in “Chapter 2 Necessity and standardization of the environmental analysis technology that addresses the international regulation of hazardous chemical substances.”5 Necessity of the standardizationComment (Hiroaki Tao)I think it will become easier to understand if you explain the chemical formula, properties, use, and what kind of environmental problem it is causing for each compound (such as nonylphenol), as well as the reasons why the existing standardization method cannot help solve the problem and the reasons why you proposed the new standardization.Answer (Sachi Taniyasu)I have added the background information on the use, environmental issues, and environmental fate for each compound because they are important in explaining the necessity of the environmental analysis technology, and modified the text so the
