Determination of Hexavalent Chromium in Drinking Water Using Ion Chromatography
INTRODUCTION Hexavalent chromium, Cr(VI), is the most toxic form of the metal chromium, a primary drinking water contaminant in the U.S. Dissolved hexavalent chromium can be determined as chromate (CrO 4 ) by ion chromatography in drinking water, groundwater, and industrial wastewater effluents as described in U.S. EPA Method 218.6 and Dionex Technical Note 26. Dionex Technical Note 26 uses a 2...
متن کاملCarcinogenicity of hexavalent chromium.
Hexavalent chromium (Cr(VI)), a commonly used industrial metal, is a well known human lung carcinogen. Epidemiology and animal studies suggest that the particulate Cr(VI) compounds, specifically the water insoluble compounds, are the more potent carcinogens; however, the carcinogenic mechanism remains unknown. Here we summarize recent Cr(VI)-induced human tumour, in vivo, cell culture and in vi...
متن کاملReview: Public Health Goal for Hexavalent Chromium in Drinking Water
Attached is my review of the chromium document. I have some serious reservations about the mechanistic aspects, as you will see.
متن کاملBiotransformation of Hexavalent Chromium by Acinetobacter iwofii
In the present study, bio reduction of hexavalent Chromium, a transition metal, known for its high solubility and carcinogenicity, using a sewage isolate was tested under controlled laboratory conditions. The objective of the study included determination of the extent of bio degradation of Cr[VI] by the isolate, characterization of the isolate and testing the degradation potential of the isolat...

Publication 1. A. Manceau et al, “Quantitative Zn speciation in smelter-contaminated soils by EXAFS spectroscopy,” Am. J. Sci. (in press, 2000). Figure 3 (top) Soil samples were taken at several depths from a contaminated site. (bottom) Model compounds derived from polarized-EXAFS data at the ESRF and μ-EXAFS data at the ALS provide a good fit with powder-EXAFS spectra from a soil sample, there...
