Assessment and remediation of carcinogenicity of drinking water contaminated with multiple heavy metals

Research grant

Project Description

In this research, we identify heavy metals that, in collaboration with iodine, act to enhance carcinogenicity in drinking water. We then reassess environmental standards for same. We also seek a method of safely removing heavy metals relating to carcinogenicity. International researchers have measured concentrations of 38 types of heavy metals within drinking water samples and patient specimens. Working with these findings, we seek to establish a method of remediation to enable continual purification into the future.
