Pilot Scale Evalaution of Ozoen and other Drinking Water Disinfectants usign Mutagenicity Testing

摘要

Mutagenicity produced by the oxidatns chlorine, chloramines, chlorine dioxide and ozone when used in drinking water treatment was examined in a pilot scale studyconducted at Edmonton, Canada. Both the Ames test, nad a yeast assay usign Saccharomyces cerevisiae (strain D7144-2) were employed. In the Ames test, chlorination produced mutagenicity the most frequently; samples obtained following ozonation were rarely mutagenic. In the yeast assay, mutagenicity was seen only infrequently. Granular activated carbon effectively removed mutagenicity for a logn period of time.
