Concentrations of Ames mutagenic chlorohydroxyfuranones and related compounds in drinking waters

Article Abstract:

A study was conducted to make a comprehensive survey of the occurrence of chlorohydroxyfuranones in drinking water and test for MX concentrations and the mutagenic activities of the contaminant. A survey of 35 localities in Finland and a sample taken from St. Petersburg, Russia, showed that MX is the most significant chlorohydroxyfuranone, accounting for 67% of the mutagenicity in TA100 mutagenicity trials. Another chlorohydroxyfuranone, CMCF, accounted for only 3% of the overall mutagenicity.
