A bioassay of 2,7-dichlorodibenzo-p-dioxin for possible carcinogenicity was conducted by administering the test chemical in feed to Osborne-Mendel rats and B6C3F1 mice. Groups of 35 rats of each sex were administered 2,7-dichlorodibenzo-p-dioxin at one of two doses, either 5, or.

Fe 3+ –H 2 O 2 mixed reagent, but not Fe 2+ –H 2 O 2, was found to be capable of degrading 2,7-dichlorodibenzo-p-dioxin (DCDD).A reaction mixture of FeCl 3 (8 mM) and H 2 O 2 (1%) caused ≈50% degradation within 6 h and >90% degradation within 24 h at 27 °C. Increasing the temperature remarkably stimulated degradation: at 70 °C, ≈% degradation was achieved within 15 by: To date, there are reports of its degradation of DD, 2,7-dichlorodibenzo-p-dioxin (diCDD) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (tetraCDD).
Although mineralization of 2,3,7,8-tetraCDD by this fungus has been observed, the metabolite was not elucidated and CO 2 evolution was quite low[ 14 ].Cited by: 2,7-DICHLORODIBENZO-P-DIOXIN.

Department of Transportation hazard labels, and a general description of the chemical. Dioxins and dioxin-like compounds (DLCs) are a group of chemical compounds that are persistent environmental pollutants (POPs). Some of them are highly toxic, but the toxicity among them varfold.
They are grouped together, because their mechanism of action is the same. Dioxin and dioxin-like compounds (referred to collectively as DLCs) are ubiquitous in the environment (ATSDR, ; Travis and Hattemer-Frey, ).
People may be exposed to background levels (i.e., low concentrations) of DLCs by breathing air, by consuming food or beverages, or by their skin coming into contact with DLC-contaminated materials (ATSDR, ).

Abstract. Like all chlorinated dibenzo-p-dioxins, the tetrachlorinated isomer 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is stable to heat, acids, and is virtually insoluble in water (2 × 10 −4 ppm) only slightly soluble in fats (44 ppm in lard oil), and more soluble in hydrocarbons ( ppm in benzene), and at its most soluble in chlorinated organic solvents ( ppm in ortho Cited by: 3.
Panellus stipticus, commonly known as the bitter oyster, the astringent panus, the luminescent panellus, or the stiptic fungus, is a species of fungus in the family Mycenaceae, and the type species of the genus Panellus.A common and widely distributed species, it is found in Asia, Australia, Europe, and North America, where it grows in groups or dense overlapping clusters on the logs, stumps Family: Mycenaceae.
