title: [Use of measurement of liver cytochrome P 450 as a water toxicity test].
abstract: The authors describe a new approach to determine the toxicity of water samples. The level of liver hydroxylating cytochrome in mice injected with water samples is assayed. This assay is used to test the toxicity of waters containing an earth extract (humic and fulvic acids). The water samples showed various toxicities desinfected with chlorine or ozone.
