Country and Sector Background

1. Background. Polychlorinated biphenyls (PCBs) are one of the twelve persistent organic pollutants (POPs), which, due to their damage to human health and the environment, were identified for elimination by the Stockholm Convention, which entered into force on May 17, 2004. China has been strongly committed to the development and implementation of the Stockholm Convention. It participated in all preparatory meetings and signed the Convention as soon as it opened for signature on May 23, 2001. China officially ratified the Stockholm Convention on August 13, 2004, and is a Party to the Convention. China has also advanced substantially in meeting the Convention requirement that Parties to the Convention submit a National Implementation Plan (NIP) to the Conference of Parties within two years after the Convention enters into force for that country. China started preparing its NIP in mid-2004 and is expected to complete it by the required date of August 13, 2006.

2. Country Situation. Only three PCB producers (in Xi’an, Suzhou, and Shanghai) ever manufactured PCBs in China and only from 1965 to early 1974 (details in Annex 1). They produced approximately 10,000 tons, including 1,000 tons of pentachlorobiphenyl (PCB5) and 9,000 tons of trichlorobiphenyl (PCB3). Some wastes may remain at production facilities, which will be addressed under the national replication program to be developed in this project (component 6, para.25) . PCB5 oils were generally used in a wide variety of open systems, such as in oil paints and exterior dopes. PCB3 was principally used in manufacturing capacitors that were used in the electricity supply industry.

3. During the 1980s, following growing health and environmental concerns, China removed most PCB-containing capacitors from service and placed them in temporary storage facilities (underground “concrete coffins” or in caves) intended to hold them for 3-20 years. Recent surveys and investigations indicate that most...
