The purposes of this project were: 1) to overview the existing international control strategies, and propose recommendations on the control of persistent organic pollutants (POPs) in Taiwan; 2) to conduct matters relating to the National Implementation Plan (NIP); and 3) to integrate the dioxin data from various databases in the Environmental Protection Administration(EPA), and continually extend the function of the Dioxin Integrated Management System. In the project, the latest status of the Stockholm Convention and the controls of endosulfan in five developed countries were collected. Based on the information collected, the endosulfan has been listed as a control substance in Toxic Chemical Substances Control Act in 2011 by the EPA. The Environmental Protection Administration also submitted a suggestion on the ban on endosulfan to the Council of Agriculture. Laws and regulations will also be reviewed by Environmental Protection Administration and Department of Health. The project held 2 NIP working group seminars to complete the report which gathered the achievements made by the Environmental Protection Administration, Department of Health, Council of Agriculture and the Ministry of Economic Affairs on the control of POPs between 2008 and 2010. As for the integration of dioxin data, the dioxin data in three different databases have been integrated into the Dioxin Integrated Management System, including the Solid Waste Incineration Management System (SWIMS), Soil and Groundwater Information Management System and Control of Stationary Sources of Air Pollution Information System. Through integration and the data collected from individual studies, there were 9,865 dioxin data in the system. Besides, the functions of the system were extended. The operational manual of “Emergency Reporting System of Dioxins Pollution” and the contact detail of reporting personnel were also updated. Moreover, the release of dioxin into air and water environments was estimated to be 58.576 gI-TEQ/year, which is lower than release in 2006 by 34.9%.
