Environmental Project, 940 – Survey of dioxin emission from PCP-treated wood

Survey of Dioxin Emission from PCP-treated Wood

Preface

PCP-treated wood has in the Substance Flow Analyses for Dioxin from 2000 and 2003 been identified as a possible source of dioxin emission in Denmark. This identification has however only been based on international studies of comparable substances and the physical and chemical properties of dioxin, as so far no international studies have been made of the dioxin emission to air from PCP-treated wood.

The objective of this project is to examine whether dioxin emission from PCP-treated wood should be regarded as a substantial source of the total Danish dioxin emission and if possible to obtain a more precise interval of the Danish dioxin emission from PCP-treated wood.

With the described objective the report is a contribution to meet the obligations in article 5 of the Stockholm Convention on Persistent Organic Pollutants (POPs). The article describes the demands on a national action plan, which among other things shall include an evaluation of current and projected releases, including the development and maintenance of source inventories and release estimates /Stockholm Convention, 2001/.

The report has been financed by the Danish Environmental Protection Agency and has during its preparation been supervised by a steering committee consisting of:

Helle Petersen, Danish EPA (Chair) Jørgen Vikelsøe, Danish National Environmental Research Institute Erik Hansen, COWI A/S
