We have developed the liquid chromatography - tandem mass spectrometry (LC/MS/MS) simultaneous analysis method of 76 agricultural chemicals which are the “Complimentary Items” in drinking water in the Japanese Waterworks Act. Further, we evaluated the validity of analytical method based on the results of the recovery tests of each chemical using tap water. Regarding the 39 chemicals, the quantification limits were lower than 1/100 of the desired values of each chemical, and the accuracy (recovery rates) and repeatability satisfied the criteria of the Japanese guideline regarding the water quality analysis. Regarding other 13 chemicals, the quantification limits were lower than 1/10 of the desired values of each chemical, and the accuracy (recovery rates) and repeatability also satisfied the criteria. Therefore, we judged that the simultaneous analytical method we have developed in the present study was applicable to the analysis of 52 chemicals in drinking water. In order to expand the LC/MS/MS simultaneous analysis method developed in the present study as an official analytical method of analyzing drinking water in Japan, we will perform verification tests using other apparatus and in other organizations.

The accident of the Fukushima Daiichi Nuclear Power Plant by the East Japan great earthquake disaster continues having a big influence on the sales slump of farm products. In our research, we predict a price change of 2011 that in the case a nuclear accident was not generated for an example Pholiota Nameko, and we aim at presuming the amount of damage after a nuclear accident. We used a multiple regression analysis in the analysis and made a high precision Pholiota Nameko mushroom price prediction model. As a result of having estimated the amount of damage in 2011 after the nuclear accident from this model, it is more than 30 million yen in Tokyo market and more than 200million yen in whole Fukushima.

Scenarios approaches are increasingly being used to study sustainable lifestyles and consumption. It is not clear, however, whether conventional scenario approaches, which have been developed for use in business, are applicable to lifestyle research. Scenario approaches must be applied appropriately; to do so, we need a deeper understanding of the approaches as well as the objectives and characteristics of lifestyle studies. In this paper, we reviewed existing literature on scenario approaches and on the application of these approaches to environmental and lifestyle/consumption studies. We distinguished different types of scenario approaches and examined their applicability to lifestyle/consumption studies. Three basic types of applications to lifestyle/consumption studies were identified: seeking followers of a lifestyle, quantification of individual scenarios, and creation of new, futuristic lifestyles. For each type, there is room for methodological improvement, and more knowledge and experiences about conducting the studies are needed to address. We also identified that several common tasks or challenges for future lifestyle studies: various lifestyles need to be described within a realistic capacity of study resources; be aware that the consideration of different values and beliefs could weaken normative aspects that are supposed to be achieved in the future; societal situations should be described in addition to lifestyle considerations; concepts of lifestyles should be clarified in the scenario-writing process; a diverse groups should participate in the scenario-writing process; and more study is needed on how to integrate quantitative and qualitative information into scenarios.
