Polychlorinated dibenzo-p-dioxins (PCDD) and Polychlorinated dibenzofurans (PCDF) are two Persistent Organic Pollutants being addressed by Stockholm Convention (SC), which is a globally binding treaty that requires Parties to minimize, or where feasible, eliminate the releases of PCDD/PCDF. This requirement necessitates the identification and quantification of PCDD/PCDF sources. To date, two national inventories have been conducted to identify and quantify the sources of PCDD/PCDF in the Philippines.
