A widely recognized laboratory for dibenzodioxins
and dibenzofurans made chemical analyses.
Contaminants: Chloropropanols; Polychlorinated dibenzodioxins
, polychlorinated dibenzofurans and coplanar polychlorinated biphenyls.
Other analytes included cotinine, polychlorinated biphenyls, phthalate metabolites, polybrominated diphenyl ethers, polychlorinated dibenzodioxins
, polychlorinated dibenzofurans, bisphenol A, triclosan, selenium, uranium, perfluorinated compounds, parabens, benzophenone, manganese, and antimony.
Saytex 8010 is an alternative to Saytex 102E (decabromodiphenyloxide), which has come under environmental pressure for generating dibenzodioxins
Cleveland, says its new Pyro-Chek LM brominated PS polymer contains less than one ppb of polybrominated dibenzodioxins
and dibenxofurans, both suspected carcinogens.
Unsafe recycling activities such as open burning and acid leaching of e-waste produce toxic combustion products including dioxin-like PCBs, and polychlorinated dibenzodioxins
and -furans (PCDD/Fs) (Frazzoli et al.
Saytex 8010 brominated flame retardant reduces risk of formation of brominated dibenzofurans or brominated dibenzodioxins
, according to John M.
For example, it is instructive to compare the task of confirming the presence of low ppb levels of pentachlorinated dibenzodioxins
present in a soil extract by SIM versus the Saturn II in full scan.
Saytex BT-93, in a comparable 82 wt% bromine matrix, produces no detectable brominated dibenzodioxins
and little, if any, 2,3,7,8-substituted brominated dibenzofurans on pyrolysis.
A significant increasing trend in prevalence of metabolic syndrome was reported with increasing quintiles of TCDD and total toxic equivalents (TEQs) [based on polychlorinated dibenzodioxins
(PCDDs) and dibenzofurans (PCDFs)] measured in the serum of 1,490 Taiwanese residents living in the vicinity of an abandoned pentachorophenol factory (Chang et al.
According to Ferro, test evaluations indicate that at detection levels of less than one part per billion, the product produces no polybrominated dibenzodioxins
The burning and subsequent collapse of the towers resulted in the release of particulate matter comprising asbestos; silica; cement dust; glass fibers; heavy metals including arsenic, beryllium, cadmium, chromium VI, and nickel; polycyclic aromatic hydrocarbons; polychlorinated biphenyls; and polychlorinated dibenzofurans and dibenzodioxins
(Edelman et al.
