Detection of the mutagenic activity of lead chromate using a battery of microbial tests

Evaluation of the carcinogenic risk of chemicals to humans

“…ln a similar assy, lead acetate, lead chloride, lead oxide and lead tetroxide were found to be inactive (Kada et a'., 1980). Lead chloride was not mutagenic in the Salmonella/microsome tes nor in plate or fluctuation tess using E. coli WP2 (Nestmann et al, 1979).…”

“…Lead chromate (Vil induced mitotic recombination in Saccharomyces cerevisiae; rat-liver supernatant reduced this activity (Nestmann et al, 1979).…”

Facile Synthesis of Graphene Oxide-Nano Titania Composites and Evaluation for Visible Light Assisted Photocatalytic Degradation of Rhodamine B

“…These composites have been characterized using XRD, FESEM, HRTEM-SAED (selected area electron diffraction), FTIR and UV-Vis DRS. It has been medically proven that contaminated drinking water with rhodamine dye could lead to subcutaneous tissue borne sarcoma which is highly carcinogenic [15]. Hence, rhodamine B dye was selected as the probe molecule for the photocatalysis study under visible light in the presence of prepared composite materials.…”

The Carcinogenicity of Chromium

“…Chromates are mutagenic in Escherichia coli and in Salmonella typhimurium (60)(61)(62)(63)(64)(65)(66)(67)(68)(69)(70)(71)(72) and influence DNA repair in Bacillus subtilis (69,73). Venitt and Levi (60) and Petrilli and de Flora (62) in a comparative study found no significant differences in dose-response between the soluble and slightly soluble compounds in either the Salmonella or the Coil system.…”
