Abstract
To clarify the characteristics of the perceived risk derived from the activities in the environment, questionnaire survey were carried out. 33 of the urban activity with risk derived from chemical exposure, the way of living and the urban metabolic system were selected. The descriptors to analyze the characteristics of these risk were the degree of experience, the degree of offered information, perceived usefulness and so on. SAS statistical program package were used to make tabulations and to score the values of each descriptor. Voluntariness to the exposure of these risks and belongingness to the environment was made sure to be the key mediator of the risk acceptance. Results obtained were as follows;
(1)Most respondents much weighed perceived risk than actual risk as to each risk from the point of personal experience of it.
(2)Involuntariness exposed to the activity and passively exposed risk from them were roughly considered as risky situation owing to the lack of the offered information.
(3)Representative chemical risk such as microcontaminants in water, agrochemicals mercury, and acid rain were both risky and beneficial domain. Though the trade-off between the perceived risk and the perceived benefit of these activities were not analyzed enough clear, especially passively exposed chemical risk were inclined to get near the region of risky and useless.
