Technical Support Document Report on Chlorinated Dioxins and Dibenzofurans Part B - Health Effects of Chlorinated Dioxins and Dibenzofurans

Determination of chlorinated dibenzo-p-dioxins and dibenzofurans in various materials.

Long-term hazards of polychlorinated dibenzodioxins and polychlorinated dibenzofurans.

During January 10-11, 1978 in Lyon, France, a joint National Institute of Environmental Health Sciences/International Agency for Research on Cancer ad hoc Working Group considered and discussed the feasibility of coordinating epidemiological studies on the long-term hazards associated with the chlorinated dibenzo-p-dioxins and chlorinated dibenzofurans (PCDDs and and PCDFs). Nineteen invited sc...

The search for chlorinated dibenzofurans and chlorinated dibenzodioxins in wildlife populations showing elevated levels of embryonic death.

Various kinds of reproductive abnormalities have been documented among wildlife species in North America. All are associated with areas of high agricultural or industrial activity and have been shown, or are assumed to be, pollutant-induced. Selected wildlife populations may therefore serve as the best indicators of the presence in the environment of compounds which have deleterious effects on ...

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...

Chlorinated dibenzodioxins and pentachlorophenol.

Introduction Pentachlorophenol is a registered anti-microbial agent whose principal use is for the preservation of wood. Typical commercial pentachlorophenol contains a variety of substances which are considered to be "in-active" from the aspect of antimicrobial efficacy. Consequently, pentachlorophenol is sold as an antimicrobial agent with 95%o active ingredients and 5%o "inert" ingredients. ...
