Optimization of the preservation condition of umu test strain;

The effects of chlorine dioxide dosage and reaction time on the acute toxicity and genotoxicity of wastewater after chlorine dioxide disinfection were studied using photobacterium bioassay and umu test.

The genotoxicity of a total of 41 surface soil samples from Tianjin Area, Northern China were examined by SOS/umu test for the assessment of regional risks associated with the spatial distribution of genotoxic substances.

The estrogenic activities and mutation effects of nonylphenol ethoxylates before and after microbial degradation were studied with the recombinant gene yeast and SOS/Umu test.

In order to evaluate the mutation effect of the 5 kinds of pesticides,SOS/Umu chromotest was applied to 2,4-D Butylate,Butachlor,Starane,Argold and Metribuzin.

In order to evaluate the mutation effect of the alkyl-hydroxybenzene, SOS/Umu chromotest was applied to 4 samples.

In this paper, in vitro umu/SOS test and in vivo Comet assay were used to assess accumulation of genotoxic substances in the soil irrigated with reclaimed water in suburbs of Beijing.

A total of 23 surface soil organic extracts from an E-waste processing area in Southern China were analyzed to screen and assess direct and indirect genotoxicity levels using SOS/umu test.

To guarantee the security of drinking water, a SOS/umu test, which is based on alterations in the.
