Dioxins and furans in fly ashes from an incinerator
Revista Facultad de Ingeniería Universidad de Antioquia, 2004 The amount of dioxins and furans in fly ashes from a medical waste incinerator was determined following the US EPA 8280A protocol. Dioxin emissions in both particulate matter and exit gas stream from the incinerator’s chimney were estimated. Furthermore,
