Evidence of Hexavalent Chromium Ingestion

Journal of Forensic Sciences, 2003
Abstract We describe the application of histochemical demonstration of chromium in a case of fatal ingestion of potassium dichromate in a suicide attempt. Using 2-(8-quinolylazo)-4,5-di-p-tolylimidazole (QTI), we could demonstrate chromium in the erythrocyte of the victim, in situ.

Isolation of hexavalent chromium-reducing anaerobes from hexavalent-chromium-contaminated and noncontaminated environments

Applied Microbiology and Biotechnology, 1996
Hexavalent chromium [Cr(VI)], is a toxic, water-soluble contaminant present in many soils and industrial effluents. Bacteria from various soils were examined for Cr(VI) resistance and reducing potential. Microbes selected from both Cr(VI)-contaminated and -noncontaminated soils and sediments were capable of catalyzing the reduction of Cr(VI) to Cr(III)

Hexavalent Chromium Substitution

2014
From razor thin tool blade coatings to shiny custom motorcycle parts, hexavalent chromium (Hex-chrome) has historically been the coating of choice for a vast array of industrial applications. Hex-chrome has many advantages over other coating alternatives including hardness, corrosion resistance, coefficient of friction, process maturity, and economic ...

Hexavalent chromium in refractories

Refractories, 1993
The ecologically dangerous chromium oxide CrO3 is formed in refractories on the phase boundaries. Upon contact of chromite with alkalis and the oxides CaO, BaO, and SrO, the conversion Cr3+ → Cr6+ in air is accelerated, and occurs with remarkable speed.

Metabolic deactivation of hexavalent chromium mutagenicity

Mutation Research/Environmental Mutagenesis and Related Subjects, 1978
Abstract Hexavalent chromium compounds (sodium dichromate, potassium chromate, chromic acid, basic zinc chromate and basic lead chromate) were found to be mutagenic for his − strains of S. typhimurium by inducing both frameshifts and base-pair substitutions.

Total chromium and hexavalent chromium occurrence analysis

Journal AWWA, 2013
Total and hexavalent chromium occurrence in the United States was investigated using three available datasets. The National Chromium and Boron Occurrence Survey, the US Environmental Protection Agency database of chromium from the Second Six‐Year Review, and California Department of Public Health water quality analysis data were obtained and analyzed ...

Cytogenetic effects of hexavalent chromium in Bulgarian chromium platers

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2002
The aim of the present study was to evaluate the genotoxic effects of hexavalent chromium (Cr(VI)) in vivo in exposed Bulgarian chromium platers by using classical cytogenetic and molecular cytogenetic analyses of peripheral lymphocytes and exfoliated buccal cells. No significant difference was observed between the exposed workers and the controls with

Inactivation of Hexavalent Chromium

Archives of Dermatology, 1962
Inactivation of chromium ion in allergic eczematous dermatitis with an antichrome agent was demonstrated by patch test studies in chromate-sensitive patients. 1,2 The purpose of this paper is to report on the stability of our antichrome agent in solutions and ointment bases, on the removal of hexavalent chromium from various materials, and on ...
