Chlorinated Dibenzodioxins and Pentachlorophenol

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. ...

Chlorinated dibenzodioxins and dibenzofurans.

The problems and universal concern about chlorinated dibenzodioxin and dibenzofuran compounds were brought to the forefront by the scientific community during the National Institute of Environmental Health Sciences' (NIEHS) Conference on this subject which was held at Research Triangle Park, North Carolina, April 2 and 3, 1973. This idea for this literature collection emanated from that scienti...

Perspective on CHLORINATED DIBENZODIOXINS And DIBENZOFURANS

Background: Angiogenesis is a fundamental process that allows tumor growth by providing nutrients and oxygen to the tumor cells. Beyond the oxygen diffusion limit from a capillary blood vessel, tumor cells become apoptotic. Angiogenesis results from a balance of proand antiangiogenic stimuli. Endogenous inhibitors regulate enzyme activities that promote angiogenesis. Tumor cells may express pro...

Carcinogenesis bioassay of chlorinated dibenzodioxins and related chemicals.

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 ...
