This Project was implemented over the period from February 1, 2011 to December 31, 2011. The main aims of the Project were to collect up-to-date information regarding international practice with respect to the management of chemical substances and environmental hormones, and to carry out a survey of the current domestic utilization status of key chemical substances, which is intended to serve as a basis for the submitting of recommendations regarding revision of relevant laws and regulations, and to assist the Environmental Protection Administration (EPA) in coordinating the division of labor between different government agencies. The results achieved in the Project included: (1) Collection and collation of information regarding the management of chemical substances in the U.S., Canada, Japan, the European Union, China, etc., and within the framework established by the Stockholm Convention, so that the selection criteria included in this information can serve as a basis for reviewing the relevant lists of regulated chemical substances that are currently used in Taiwan. This work helped bring about the adding of 27 additional toxic substances – including formamide, endosulfan and phthalates – to the lists; in addition, recommendations were submitted regarding the framework for revision of the Toxic Chemical Substances Control Act and of the related sub-statutes and management tools. (2) Collection and collation of information regarding the management of environmental hormones in the U.S., Canada, Japan, the European Union, China, etc., as well as providing assistance for the convening of cross-agency management team meetings and holding a conference on environmental hormone management; in addition, sampling work has been completed with respect to 45 items (including commercially-available cleaners, paints, toys, etc. (3) Completion of a survey of the current state of domestic utilization of 17 substances subject to observation. On the basis of the conclusions reached at this year’s meeting of the Toxic Chemical Advisory Council, on July 20, 2011 it was announced that an additional four substances – including benzyl butyl phthalate (BBP) – would be added to the list of regulated toxic chemical substances, while hydrofluoric acid and tetramethylammonium hydroxide (TMAH) would not be added to the list; it was recommended that, with regard to a number of other substances, where either there were currently no firms using these substances in Taiwan (a situation which applied to six substances, including tetraboron disodium heptaoxide hydrate) or else it had not yet been possible to compile adequate background information, further surveys and evaluation should be undertaken. (4) Other Project work items that have been completed included the implementation of emission reduction guidance with respect to five key categories of regulated chemical substances (including benzene), the holding of six on-site guidance sessions involving academic institutions, the publication of 24 issues of the e-paper, and the compilation (based on translated materials) of Chinese-language abstracts of information regarding 15 categories of chemical substances (including captafol) to help entities in various sectors gain a more thorough understanding of recent trends in toxic chemical substance management.
