In this paper the polychlorinated-dibenzo dioxins and furans (PCDD/Fs) release is analyzed during an hydrothermal carbonization process of the organic fraction of municipal solid waste (OFMSW). Two models to estimate the quantity of PCDD/Fs that can be released during this kind of process are presented in this paper. The first model follows a mass balance approach; the second one develops a phe...

SL 2: Background 1 First of all, I’d like to touch on the background of this study. As you know well, persistent organic pollutants (POPs) representing polychlorinated dibenzo-p-dioxins, dibenzofurans, PCBs, and organochlorine insecticides are lipophilic stable contaminants. They have been detected in a wide range of environmental media and biota, and have been of great concern on their toxic e...

Dioxins may have an impact on the human immunological system, which would increase the risk to develop allergic diseases, such as atopic dermatitis. In the present study, we measured serum levels of Th1- and Th2-favored chemokines in 233 Yusho patients who attended annual medical check-ups from 20.06 to 2009 and in 97 control subjects. Serum levels of CCL5, CCL17, and CCL27 in Yusho patients we...

Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), two groups of structurally related chlorinated aromatic hydrocarbons, generally referred to as “dioxins” are of great concern due to their extreme toxicity and presence in all compartments of the environment. Since they occur at very low levels, their analysis is complex and challenging, and there is a need for cost-efficient,...

Municipal solid waste incineration (MSWI) fly ash contains highly toxic heavy metals and polychlorinated dibenzo dioxins/furans (PCDD/Fs), which are a type of hazardous waste. The pollution characteristics have changed with the development stoker grate incinerators treatment technology; however, no research has been focused on this in recent years. In study, 12 samples were collected from 9 pow...
