Embryotoxicity and fetotoxicity following intraperitoneal administrations of hexavalent chromium to pregnant rats

Embryotoxicity and fetotoxicity of inhaled or ingested vinylidene chloride in rats and rabbits.

Embryotoxicity and Fetotoxicity of Inhaled or Ingested Vinylidene Chloride in Rats and Rabbits. MURRAY, F. J., NITSCHKE, K. D., RAMPY, L. W., AND SCHWETZ, B. A. (1979). Toxicol. App/. Pharmacal. 49, 189-202. The teratogenic potential of inhaled or ingested vinylidene chloride was evaluated in Sprague-Dawley rats and New Zealand white rabbits. Both species were exposed to the test material by in...

Carcinogenicity 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...

Acute severe chromium poisoning after dermal exposure to hexavalent chromium.

Severe acute chromium poisoning related to dermal involvement has rarely been reported in the literature. We report a case of acute severe chromium poisoning through skin exposure as a result of a chemical burn of 15% of the body surface area and multiple organ failure after short-term exposure. Medical interventions, including mechanical ventilation, continuous venovenous hemofiltration, and p...

Microbial Reduction of Hexavalent Chromium

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...
