Unintentional formation and emission of the persistent organic pollutants HCB and PCBs in the Nordic countries

Documentation of existing information regarding sources and emissions to air, water and soil, with focus on reporting obligations according to the Stockholm Convention, the UNECE POP protocol, and PRTR registers

In recent years reporting requirements regarding emissions and releases of unintentionally formed persistent organic pollutants (POPs) have been laid on parties to international agreements and members of the EU. Such obligations include those under the Stockholm Convention on Persistent Organic Pollutants, the UNECE POP and PRTR protocols and the EU PRTR regulation. The aim of this project has been to assess, whether existing knowledge and data are adequate for the Nordic countries to be able to estimate the emissions eventually to be reported. The project reveals that there is a substantial lack of knowledge related to potential sources in the Nordic countries. It also suggests that even though many of the main potential sources are the same, the relative importance of them differs between countries.

Identification of sources

For the identification of sources of unintentional emissions of HCB and PCBs, the reporting guidelines under the Protocol on Pollutant Releases and Transfer Registers (PRTR) are used. The Protocol on Pollutant Release and Transfer Registers (PRTR) was adopted on 21 May 2003 during the fifth 'Environment for Europe' Ministerial Conference in Kiev (Regulation (EC) No 850/2004). The protocol, which applies to 36 European countries and the European Union, is the first legally binding international instrument on pollutant release and transfer registers. PRTRs are inventories of pollution released to all media by industrial sites and other sources. As such, the PRTRs implementing the PRTR Protocol will in the long run contain two types of data: facility-level data and data for socalled diffuse sources. A description of diffuse sources, e.g. road transport and domestic heating, where such data is available are presented in section 2.2., while potential sources to be reported in future at facility level are described as potential point sources in section 2.1. In general terms, data for the two types of sources must be integrated into an overall picture of emissions to air, water and land and off-site transfers of waste and of pollutants, here UPOPs, in wastewater (E-PRTR Regulation (EC) No 166/2006).
