Previous studies have focused on reducing, reusing and recycling activities in the factor analysis for environmental behavior models. However, it is time for communities that have experienced a higher level of waste reduction activities to put more efforts on not just waste reduction but also wise use of resources and town development.

This study aims at examining a cyclical environmental behavior model consisting of three factors, namely, waste reduction, wise use of resources, and town development, based on the survey conducted in Ohki Town, Fukuoka Prefecture, Japan.

The study expects that environmental attitudes are determined by environmental perception while environmental behaviors are determined by behavior evaluation. On top of this, a cyclical model containing three variables, namely, environmental behaviors, public participation, and a sense of values, was tested using Covariance Structure Analysis.

As a result, environmental perception and behavior evaluation were not identified as suitable in the model. Instead, a cyclical part of the model was confirmed by RMSEA＝0.059.

This proved that a combination with a sense of values and town development is more effective than the influences of environmental perception and behavior evaluation in further promoting resource circulation behavior for an advanced community.

Chlorophenols are known as intermediate of dyestuff and insecticide arises on the process of bleaching paper pulp. They have strong toxicity to aquatic lives. In nature, it is known co-existing substances such as humic acid (HA) affects the toxicity of heavy metals and organic matters including cationic/anionic surfactants. The purpose of this study is to reveal the adsorption mechanism of HA and Chlorophenols. First, the chemical property of HA was examined with acid-base titration. This experiment shows HA has dominant sites of adsorption such as carboxyl group and phenolic hydroxyl group analyzed with NICA (Non Ideal Competitive Adsorption)-Donnan model. Then, adsorption between HA and chlorophenols including 2,4,6-trichlorophenol (2,4,6-TCP), 2,4-dichlorophenol (2,4-DCP), p-chlorophenol (p-CP) was examined by shaking experiment. The pka (acid dissociation constant) of each chlorophenols were within the range of 6 to 10. Amount of 2,4,6-TCP adsorbed onto HA was drastically decreased along with pH increase though 2,4-DCP was slightly decreased. No relationship between amount of p-CP adsorbed and pH of solution was found. 2,4,6-TCP is electronegatively charged because the proton dissociation generates repulsion between 2,4,6-TCP and HA. Moreover, a positive correlation between partition coefficient (logP) and amount of adsorption was suggested.

This study elucidated the factors affecting the opinion-expression process of social acceptance on public beneficial projects. Hypotheses on the process following acceptance self-evaluation until opinion expression on acceptance were established, identifying two judgment stages: judging the necessity of re-evaluation for self-acceptance and that of cover-acceptance opinion for public expression. For the latter, two experiments were conducted to examine four factors affecting judgment and opinion. The results of experiment 1 suggested that people expressed a more desirable opinion of another person when they have weak, rather than strong, motivations toward plan realization. However, cognition on consequence control did not affect opinion expression. Experiment 2 findings revealed that people expressed a more desirable opinion of another person when they predicted creating a negative impression on the person, than when they expressed genuine self-opinion; the same tendency was observed for when they predicted high-life difficulty than low-life difficulty, owing to expression of genuine self-opinion. Thus, the need for fostering situations wherein people could easily express genuinely held self-opinions on public beneficial projects was discussed.

Environmental science research is required not only scientific knowledge by interdisciplinary research among scientists but also various forms of collaborative research that integrates living knowledge (including scientific knowledge) gained by the concrete experience of the public. In the interaction between stakeholders through “dialogue and collaboration” in collaborative research, it is necessary to obtain public’s understanding and empathy for the research in society, especially in the field of environmental science. On the other hand, it is considered that the stage of development of science shifts from “growth stage” by interaction with technology to “maturity stage” by “dialogue and collaboration” between scientists and the public. The connection between science and “dialogue and collaboration” at the stage leads to the creation of new values and way of life to resolve the solution of environmental and social issues in scientific civilization. Namely, it is concrete science and technology backed up by specialized scientific knowledge that can solve various environmental issues. Therefore, the technical solution of individual issues is merely symptomatic treatment, and we need to change our own values and way of life that caused such issues by “dialogue and collaboration”.
