Antifouling paints containing DDT are mainly used on sea fishing ships. There are 300,000 medium and small size ships widely distributed along the 18,000 km. coastline in China, which consume 10,000 metric tonnes (MT) antifouling paints. Approximately half is DDT based antifouling paint, and the other half is TBT based antifouling paint. Because DDT is a Persistent Organic Pollutant, it can damage sea organisms and sea ecosystems, and be accumulated in the bodies of sea organisms when it is released into sea from the antifouling paints coated on the ships’ surface. Use of DDT in this manner is not considered a permitted use under the Stockholm Convention, and there are no specific exemptions available to continue such production and use. Thus, China is obliged to take action to phase out the use of DDT as additive in the production of antifouling paint. In cooperation with the United Nations Development Program (UNDP), a project titled Alternatives to DDT Usage in the Production of Antifouling Paint has been developed and got GEF Council approval in August, 2006, and GEF CEO Endorsement in July, 2007. The key objective of this project is to take measures to eliminate the use of DDT as an additive for antifouling paints, and to establish and promote the use of sustainable alternatives to DDT/TBT-based antifouling paints. The binding objective of the project is to eliminate the use of DDT in production of antifouling paint by conversion to technically feasible, economically viable, and environmentally friendly alternatives. In addition, the prospective objective of the project is to establish a long-term mechanism to protect marine environment and human health from pollution of harmful antifouling systems by supporting China’s signature of the International Convention on the Control of Harmful Anti-fouling Systems on Ships (the IMO Convention) based on the technologies, experience and instruments obtained from phase out of DDT antifouling paint.
The Ministry of Environmental Protection (MEP), through its Convention Implementation Office (CIO/MEP), and the UNDP will be respectively the national executing agency and the international implementing agency of this four-year project from November 2007 till December, 2011. One of the outcomes of the project will be to make the conversion from DDT based antifouling paints to alternatives, adopting multiple means of technological support, policy induction, market regulation, and awareness raising and education to promote the conversion.
The project was launched in November 2007 with an Inception workshop where stakeholders from the government, industry, research institutions and public interest organizations participated. A work plan was presented incorporating - Panel testing from the summer of 2008 to the summer of 2009 on some 40 paint formulations
- On-ship testing of about one-half of these formulations over about a year starting a few months later.
A workshop on Alternatives to DDT containing paints was held in February 2008. At his workshop data requirements for the panel testing were agreed. An expert meeting was held on July 11th, 2007. At this meeting paint formulations for the on-ship tests were selected from those applied in the panel test. Based on criteria for physico-chemical properties, low tin content and low to intermediate copper content, about 20 paint formulations were selected for on-ship tests. The program was delayed due to changing priorities for project staff caused by the earthquake in Sichuan province in the spring of 2008, and to the prohibition of transports in Beijing around the Olympic games. Therefore the on-ship test may begin in March 2009 and last until March 2010. An initial set of data requirements for environmental risk assessment was decided by national experts in June 2008 and preliminary dossiers submitted in June and July 2008. |
