Usage

General Description

2,3,4,6,7,8-Hexachlorodibenzofuran is a highly toxic and persistent organic pollutant. It is a member of the dioxin family, which are known to be potent carcinogens and disruptors of the endocrine system. This chemical is formed as a byproduct of certain industrial processes, such as waste incineration and the manufacture of certain chemicals and pesticides. It is highly resistant to degradation in the environment and can accumulate in the food chain, posing a risk to human and animal health. 2,3,4,6,7,8-Hexachlorodibenzofuran has been classified as a persistent organic pollutant by the Stockholm Convention, and its production and use are regulated or banned in many countries to minimize its environmental and health impacts.

Formation and emission status of PCDDS/PCDFS in municipal solid waste incinerators in korea

This study was carried out to examine the formation and the emission status of polychlorinated dibenzo-p-dioxins/ polychlorinated dibenzofurans (PCDDs/PCDFs) in the flue gases of commercial-scale municipal solid waste (MSW) incinerators, and thus to provi

Effects of oxygen on formation of PCB and PCDD/F on extracted fly ash in the presence of carbon and cupric salt

The effect of oxygen-nitrogen atmosphere (N2 + 10%O2, N2 + 1%O2 and 99.999% N2) on the formation of PCB, PCDD and PCDF by the de novo synthetic reactions in the system consisting of extracted fly ash

Study of evolution of PCDD/F in sewage sludge-amended soils for land restoration purposes

The evolution of polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF) in sewage sludge-amended soils used in the restoration of degraded lands, like quarries, has been studied. Two experiments were performed: one in the lab, under controlled conditions, and another in a quarry. Two different doses of sewage sludge were applied in both experiments (with two types of application in the quarry experiment) and the evolution of the amended soils were compared with that of the respective control soils (without addition of sewage sludge). The samples were analyzed with a previously validated method by HRGC-HRMS after the extraction and the necessary clean-up steps. The results reveal that polluted sewage sludge increases PCDD/F concentration in soils and that these compounds are persistent in the matrix after long periods of time. (C) 2000 Elsevier Science Ltd.

Laboratory and field experiments were conducted in Spain to examine the evolution of PCDDs and PCDFs in sewage-sludge-amended soils. The PCDD/F concentrations were measured in the original sewage sludge and in soil samples over time. Results from the laboratory showed that the PCDD/F concentration in amended soils was related directly to the sewage-sludge dose applied. After 1 yr, however, no evolution of PCDD/Fs was observed in any sample. In the field, high dispersion was observed, which did not allow establishment of a concentration trend over time.
