Orlando, Fla. (April 8, 2019) – Antioxidants such as vitamin C could help reduce harmful effects from hexavalent chromium, according to a new study performed with human cells. The contaminant, which is often produced by industrial processes, was featured in the biographical movie Erin Brockovich.

Federal data from nationwide drinking water tests show that the compound contaminates water supplies for more than 200 million Americans in all 50 states. The concentration of hexavalent chromium that is safe for drinking water is now under review by the U.S. Environmental Protection Agency.

“This is the first study to use human cells to test the effects of hexavalent chromium and protection by antioxidants,” said Tim Mayotte, an undergraduate student at Olivet Nazarene University who performed the study. “If the new findings are further validated and go on to clinical trials, it might be possible to treat at-risk water sources with antioxidants like vitamin C to lower the risk for cancer caused by hexavalent chromium.”

Mayotte will present this research at the American Society for Biochemistry and Molecular Biology annual meeting during the 2019 Experimental Biology meeting to be held April 6-9 in Orlando, Fla.
