Studies on the mechanism of toxicity of the chlorinated dibenzo-p-dioxins.

چکیده
Concern about the potential health hazards resulting from environmental pollution by the chlorinated dibenzo-p-dioxins and dibenzofurans arises from our recognition of the extraordinary potency of these compounds as toxins and teratogens and their inadvertant dispersion in the environment as contaminants of chlorinated phenolic products. Questions concerning the extent of environment contamination and those concerning the mechanism of toxicity produced by these compounds are at present unanswerable. Several papers in this symposium have presented the historical background which led to our current understanding and concern about this problem: (1) the "chick-edema" outbreaks caused by "toxic fats" in poultry feed and the eventual isolation and identification of a hexachlorinated dibenzo-p-dioxin; (2) the occurrence of acne among workers in several 2,4,5-T factories and recognition of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) as the etiologic agent; (3) the NCIcommissioned study on the potential teratogenicity, carcinogenicity and mutagenicity of 2,4,5-T; (4) and the widespread use of Agent

Degradation of Chlorinated Dibenzofurans and Dibenzo-p-Dioxins by Sphingomonas sp. Strain RW1.
The ability of the dibenzofuran- and dibenzo-p-dioxin-mineralizing bacterium Sphingomonas sp. strain RW1 (R.-M. Wittich, H. Wilkes, V. Sinnwell, W. Francke, and P. Fortnagel, Appl. Environ. Microbiol. 58:1005-1010, 1992) to oxidize chlorinated derivatives of dibenzofuran and dibenzo-p-dioxin was analyzed. Strain RW1 degraded several mono- and dichlorinated dibenzofurans and dibenzo-p-dioxins, b...
متن کاملAnalytical and confirmative techniques for dibenzo-p-dioxins based upon their cation radicals.
A large number of analytical methods for the detection of chlorinated dibenzo-p-dio-xins have been reported in the past few years (1-8) ; generally, these methods involve the use of gas-liquid chromatography (GLC) or GLC coupled with mass spectrometry (MS). Detection limits of about 1 ng have been reported for GLC-MS techniques with the demonstrated capability of detecting these compounds in th...
متن کاملQSAR Studies of the Dioxins and Interaction of OCDD with Calix[4] Arene Using DFT
Quantum chemical calculations, based on Density Functional Theory (DFT) method, were performed on Calix[4]arene and Polychlorinated Dibenzo-p-dioxins (PCDDs) in gas and liquid phases for comparison purposes. The simulation results show the 1,2,3,4, 6,7,8,9-octachlorodibenzo-p-dioxin (OCDD) is quite a reactive dioxin. This paper attempts to examine the possibility of dioxin adsorption by Calix[n...
متن کاملMechanisms of the biological effects of PCBs, polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans in experimental animals.
Polychlorinated biphenyls, certain polychlorinated dibenzo-p-dioxins and certain polychlorinated dibenzofurans cause a variety of biological effects in experimental animals. The mechanism of the induction of certain enzymes is perhaps best understood. That is, there is binding of certain chlorinated biphenyls, dibenzo-p-dioxins and dibenzofurans to a receptor, translocation of the compound-rece...
