Abstract

Identification of source is very important for taking better countermeasures against dioxin pollution. Analyzing all the tetra- to octa-chlorinated PCDD/DF congeners, the source identification powers of different levels of dioxin monitoring information are compared. Also the method for estimating contributions from different sources to the dioxin pollution is proposed.
