PART II DEFAULT EMISSION FACTORS

7 – Production and Use of Chemicals and Consumer Goods


This section provides brief descriptions of the processes from the chemicals and consumer goods production sector which contribute to the formation of PCDD/PCDF releases, and gives information based on measured data to estimate/quantify release of PCDD/PCDF from the various activities in this sector.
As can be seen from Table X, there are five major source categories. It can also be seen that releases of PCDD/PCDF may occur via various pathways resulting in contamination of air, water, and soil or in the product. In addition, the residues may contain PCDD/PCDF contamination as well. For all the activities listed in this sector, the major emissions are not into air but into other compartments.
