Polychlorinated dibenzo-p-dioxins and dibenzofurans formed from sucralose at high temperatures

POLYCHLORINATED DIBENZO-p-DIOXINS AND DIBENZOFURANS AS PRODUCTS OF PHOTODEGRADATION OF CHLOROPHENOLS

Results of the study into photodegradation of 2,4,6-trichlorophenol and pentachlorophenol in aqueous solutions have been presented. Quantum yields and rate constants of the reactions were determined. Intermediate products were identified by GC/MS method. The experiments confirmed formation of polychlorinated dibenzo-p-dioxins and dibenzofurans in photochemical reactions. The findings showed tha...

Degradation of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans by the white rot fungus Phanerochaete sordida YK-624.

A method for the degradation of dioxins by white rot fungi was developed. Degradation of a mixture of 10 kinds of tetra- to octachlorodibenzo-p-dioxins (polychlorinated dibenzo-p-dioxins [PCDDs]) and tetra- to octachlorodibenzofurans (polychlorinated dibenzofurans [PCDFs]), which were chlorinated at 2-, 3-, 7-, and 8-positions of the molecules, by the white rot fungus Phanerochaete sordida YK-6...

Polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and biphenyls (PCBs)

Juha Jokiluoma Formation and Reduction of Polychlorinated Dibenzo-p-dioxins/dibenzofurans in Fluidized Bed Combustion of Solid Waste

TAMPERE UNIVERSITY OF TECHNOLOGY Master’s Degree Programme in Environmental and Energy Technology JOKILUOMA, JUHA: Formation and Reduction of Polychlorinated Dibenzo-pdioxins/Dibenzofurans in Fluidized Bed Combustion of Solid Waste Master of Science Thesis, 89 pages, 9 appendix pages October 2013 Major: Power Plant and Combustion Technology Examiner: Professor Antti Oksanen

Polychlorinated dibenzo-p-dioxins and dibenzofurans in fly ash and cinders collected from several municipal incinerators in Japan.

Determination of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in fly ash and cinders collected from nine municipal incinerators in Japan was made. The concentrations of PCDDs and PCDFs in this study were generally in the same range as those in Europe and North America. However, the rather different congener composition compared with those published already...
