Meanwhile, this project has also referenced the local information like executive experience of environmental risk assessment in Taiwan, the data from the historical concentration investigation for the environmental chemical distribution, and the development of building local parameters. From the management strategy and methods for environmental risk assessment of chemical substances from other nations, this project has planned and proposed the assessment and information integration structure for environmental risk from chemical substance, and the general investigation plan for the environmental chemical distribution. Besides the process mentioned above, this project has also collected suggestions from experts by holding expert consultations as a foundation to develop an operation process for the environmental risk assessment of chemical substances and an integrated data base of environmental risk information.
