Evaluation and Optimization of Chromium Removal from Synthetic Aqueous Solutions by Powdered Spirogyra

International Archives of Health Sciences, 2015
Aims Heavy metals are the main pollutants in nature. Chromium is a heavy metal which is widely used. Hexavalent chromium solubility and mobility in aqueous solutions is so high and it is easily reduced.

Carcinogenicity of hexavalent chromium.

The Indian journal of medical research, 2009
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.
