**8. Main anthropogenic based dioxin and furan source categories**

Contrast to natural phenomena, anthropogenic source is potential or potent for emission of persistence organic pollutant such as polychlorinated dibenzodioxin and polychlorinated dibenzofuran (PCDD and PCDF). Unintentional persistence organic pollutants (PCDD and PCDF) are produced from four general types of anthropogenic activities found in a given country and city ([2]).


However, it is impossible to found out these source categories in all countries, as well as cities at the same level. It has variations on the economic activities of the countries or cities. The detail source groups are discussed below.

## **8.1. Source group 1—waste incineration**

Waste incineration is the predominant anthropogenic activity that contributes to the emissions of unintentional persistence organic pollutants such as dioxin and furan. Under waste incineration, five sub-categories are identified and listed such as municipal solid waste incineration, hazardous waste incineration, medical waste incineration, light fraction shredder incineration, sewage sled incineration, and animal carcass incineration [2].
