Infrared and x-ray spectroscopic studies of the copper(II) oxide mediated reactions of chlorinated aromatic precursors to PCDD/F
… dibenzo-p-dioxins and dibenzofurans (PCDD/F) are toxic compounds produced in combustion systems such as incinerators, and their emissions are an important environmental issue. Chlorinated phenols and benzenes form PCDD/F through heterogeneous reactions following adsorption onto fly-ash …

Experimental field studies and predictive modelling of PCB and PCDD/F levels in Australian farmed Southern Bluefin Tuna (Thunnus maccoyii).
… dibenzo-p-dioxins / dibenzofurans (PCDD/Fs). This research presents the investigations and experimental validation of a predictive model that can be used to address the levels of residues in the fillets of farmed SBT at harvest from feeding (as the source) when applied to SBT …

Iron (III) Oxide and Copper (II) Oxide Mediated Formation of PCDD/Fs from Thermal Degradation of 2-MCP and 1,2-DCBz
… dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) which occurs inexorably from most thermal and combustion processes constitutes a major toxic component of environmental pollutants. Generally, it is well established that transition metal-mediated reactions account for the majority of …

Thermal treatment of organic contaminated solids and waste : experiment, model and mass balance
… percent of the energy. Data on concentrations of PCDD/F in the feed, and in the effluent from modern Municipal Solid Waste Incinerators (MSWI) are surveyed and evaluated to determine if more PCDD/F are destroyed than formed in the Municipal Solid Waste (MSW) incineration process. Tile results show …

Il contributo di sorgenti locali sull'impatto ambientale da Diossine e Furani
Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are ubiquitous contaminants, mainly released into the environment during combustion processes (point sources), but also from other sources (traffic, waste incinerators, uncontrolled combustion). This Ph.D. thesis is …

Understanding and enhancing multi-pollutant control using carbon-based materials
… polychlorinated dibenzo-p-dioxins and -furans (PCDD/F), taking advantage of carbon’s adsorptive and catalytic properties. A simple, one-step technique based on ultrasonic spray pyrolysis was developed to prepare potentially catalytic carbons in a simpler and potentially more sustainable process. …

Biochemistry of micro-polutants in sediments of Mtoni estuary, Tanzania
… tropical mangrove sediments. Moreover, metals, PCDD/Fs and dioxin-like PCBs were analysed to describe their current sources and fates in response to anthropogenic and natural changes. Lastly, the study intended to determine and compare the variability in the distribution of potential …

Assessment of dietary background exposure of the Irish adult population to dioxins and PCBs particularly taking into account additional exposure due to the 2008 Irish dioxin food contamination incident
Irish monitoring data on PCDD/Fs, DL-PCBs and Marker PCBs were collated and combined with Irish Adult Food Consumption Data, to estimate dietary background exposure of Irish adults to dioxins and PCBs. Furthermore, all available information on the 2008 Irish pork dioxin food contamination incident …
