Abstract
Assessment of Dioxin and Furan Emission Levels and Management Practices in Addis Ababa, Ethiopia
Highlights
Persistent organic pollutants (POPs) are compounds that resist chemical, biological and photolytic degradation due to their inherent characteristics.[1]
The quality of gasses from each category was calculated using grams toxic equivalents (TEQ)/year (g TEQ/a) and the sum of emission of all categories generalized the total amount of PCDD/polychlorinated dibenzofurans (PCDFs) released in Addis Ababa
The annual release of dioxin and furan was determined based on emission factors and activity rate of pollutants with a method described by the United Nations Environmental Programme (UNEP).[8]
Summary
Persistent organic pollutants (POPs) are compounds that resist chemical, biological and photolytic degradation due to their inherent characteristics.[1] Their low water solubility and high lipid solubility facilitate their bioaccumulation in fatty tissues of living organisms. Many of these compounds are semi-volatile, which enable them to be transported long distances through the atmosphere. This study aimed to identify sources of dioxin and furan emissions, quantify their release into various environmental medias and assess related management practices. Several sources of dioxin and furan emission were identified and the present study found that their management is inadequate.
