In this project, four main tasks were accomplished. Firstly, we assisted in reviewing the risk assessment information of chemical substances and offered consulting services to registrants. A total of 12 cases of new chemical substances and 248 cases of existing chemical substances were reviewed completely this year. To facilitate the registration of risk assessment for existing chemical substances and collect exposure information in Taiwan’s industries, we organized five helpdesk meetings and conducted two factory visits. Additionally, we publicly released the "Guidance on Chemical Substances Hazard and Exposure Assessment", produced a series of educational videos, and strengthened the promotional and counseling effects by organizing a seminar. In the meantime, we summarized frequently asked questions and provided suggestions for adjustments to the "ChemisPecX". Secondly, we completed recommendations for the registration of risk assessment and provided examples of hazard assessment reports for ten existing chemical substances. These resources are intended for future consulting services. Additionally, we utilized dossiers for new chemical substances as samples to test the screening process for priority substances and subsequently deliberated on follow-up risk assessment methods. Thirdly, we established the information disclosure documents for 30 chemical substances to promote hazard information application. The hazard information from registrant’s dossiers and international databases were also summarized, and the results were used to complete the abstracts of hazard information for two substances. Furthermore, we discussed and adjusted an existing abstract of hazard information with the registrant, evaluating the rationality of the registration information. Finally, in order to meet the needs of practical applications, we optimized and piloted a model for selecting the priority substances. We used a chemical substance with highly hazardous properties as an example to gather information required for risk management and policy assessment by collecting international information and visiting industries. Regarding the selecting model, we compared it with the substance-selecting methods and results from related projects, explored the differences, and provided suggestions for adjustments and applications. This year, our project provided essential information for hazard and exposure evaluation. These results could contribute to establishing the risk assessment system of chemicals in Taiwan.
