||The various aspects of the biological and photobiological action of pollutants on aquatic microorganisms have been explored in a series of studies covering a wide range of chemical species and two classes of aquatic microorganisms, paramecia and bacteria. Certain metal ions, insecticides, polycyclic amines and mycotoxins are capable of drastic alteration of the life processes in test strains of either bacteria or paramecia or both. In some cases concurrent exposure to light and the pollutant was necessary and in others the toxic and/or mutagenic reactions were independent of light exposure. In particular the uranyl ion, beta naphthyl amine, and aflatoxin B1 were phototoxic while the insecticide, phygon, was strongly dark-toxic. All agents affected Paramecium caudatum and all but aflatoxin B1 affected Escherichia coli. (Author Modified Abstract)
