Health risk of iodine and I-DBPs

Iodide pollution in surface water and groundwater in many areas of China is widespread and salt fortified with KIO3 or KI is mandatory in China. Iodide pollution is a serious problem in China not only because it could lead to iodide-induced hyperthyroidism but also because the involvement of iodide lead to the formation of iodinated DBPs, such as iodine containing trihalmethanes (THM) and halocetic acids (HAA), which have been shown to be more geno- and cytotoxic than brominated and chlorinated DBPs. However, this problem has not been given enough attention by the Chinese government.

Our group has assessed the risk of iodine pollution and iodinated disinfection by products (I-DBPs) formation in China, studied the mechanisms of I-DBPs formation and developed new technologies to control iodine and I-DBPs.
