The achievements made in this project included: 1) The latest international control strategies extracted from the Stockholm Convention were collected, and recommendations for controlling strategies of persistent organic pollutants (POPs) will be shortly proposed to related administrative agencies in Taiwan. ; 2) Three NIP working-group seminars were held to gathered the achievements made by the Environmental Protection Administration (EPA), Department of Health, Council of Agriculture and the Ministry of Economic Affairs on the control of POPs in 2011. Additionally, the EPA held “2012 Environmental Hormones and Persistent Organic Pollutants Conference” to enhance public awareness of POPs and demonstrated the goals made by Taiwan Government; 3) Collected the emission factors for top 10 toxic substances released to environments and drafted the “Toxic Substance Release Calculation Guidance” as well as corresponding policies. In addition, this project has accomplished 14 on-site inspection and performed exposure measurement of 1,2-dichloroethane and vinyl chloride in 13 sample. The overall release and emission factor of 1,2-dichloroethane and vinyl chloride in each manufacturing factor was estimated based on chemicals measured. 4) As for the data integration of dioxins, three different databases have been integrated into the Dioxins Integrated Management System that is consisted of the Solid Waste Incineration Management System (SWIMS), the Soil and Groundwater Information Management System (GIMS), and the Control of Stationary Sources of Air Pollution Information System (CSSAPIS). Through the integration and the data collection from individual study, 17,378 entries of exposure measurement of dioxins were included in this system. Besides, the functions of the system were further extended to enhance its capabilities. The operational manual of the “Emergency Reporting System of Dioxins Pollution” and the contact information of reporting personnel were updated. Moreover, the release of dioxins into air and water environments in 2011 was estimated to be 56.49 g I-TEQ/year, which is lower than the levels measured in 2006 by 37%.
