"Thirty-three water and effluent samples; fourteen lake, twelve river, and seven effluent, were concentrated/extracted by four procedures; liquid/liquid solvent extraction, XAD resins, flash evaporation, and membrane filtration. The resultant subsamples were tested for mutagenic activity using five strains of Salmonella typhimurium, TA98, TA1538, TA1537, TA100 and TA1535. Three different experimental procedures were followed; with the addition of mammalian microsomes (S-9 mix) to the reaction mixture, without the addition of microsomes, and with preincubation of bacterial cells, microsomes, and sample"--Abstract, page [1].
