DIOXINS AND FURANS; AND HOSPITAL WASTE INCINERATION

Modern Technologies to Reduce Emissions of Dioxins and Furans from Waste Incineration

Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF) are fonned unintentionally as bypro ducts of waste combustion and many other thelmal industrial processes. Today PCDDIPCDF is known as one of the most toxic groups of organic substances. Furthelmore, they are perceived to be carcinogenic. Although many questions about the toxicological effects of PCDDIPCDF are sti...

Formation of Dioxins and Furans during Municipal Solid Waste Gasification

Thermal treatment is an interesting strategy to dispose of municipal solid waste: it reduces the volume and weight of the material dumped in landfills and generates alternative energy. However, the process emits pollutants, such as dioxins and furans. The present study evaluated MSW gasification-combustion integrated technologies in terms of dioxin and furan emission; and compared the obtained ...

Hospital infectious-waste incineration dilemmas.

Metals as Catalysts during the Formation and Decomposition of Chlorinated Dioxins and Furans in Incineration Processes.

Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are found on fly ash and in flue gas of municipal waste incinerators. Municipal waste incinerators seem to be the most important source for PCDDs and PCDFs emitted into the air during the last decades. PCDD/F formation takes place in the cooler zones (250 °C-450 °C) of a municipal waste incinerator, at the elect...

Isomer pattern and elimination of dioxins in workers exposed at a municipal waste incineration plant

The aim of this study was to clarify patterns of serum concentrations of dioxins in the employees of a waste incineration plant and to estimate elimination rates and half-lives of serum dioxin isomers, and the maximum serum concentrations of dioxin isomers at the time of plant shutdown. Sixteen subjects participating 3 times or more in annual health examinations during an 8-yr period from 2000 ...
