PCDD's (Dioxins) and PCDF (Furan) were contaminants detected in almost all compartments and found in very small amounts. PCDD’s and PCDF are multimedia contaminants which once released into the environment will disturb the balance of environmental components. PCDD’s and PCDF are never produced intentionally, they are formed as a by-product of industrial processes and combustion processes. Waste incineration is considered to be the main source of PCDD’s and PCDF emissions that pollute the environment. So that every waste incineration process needs to be tested for PCDD's (Dioxin) and PCDF (Furan) compounds.
