- A simple generic toxicity method (test) is proposed using baker's yeast to mediate the reduction of the colourless triphenyltetrazolium chloride (TTC) to red, 1,3,5-triphenyl formazan, which can be extracted by dimethyl sulfoxide (DMSO), enabling the identification of reducible toxic compounds (e.g. cadmium, fipronil) in water for consumption.
