ABSTRACT

Aim of the present study Vas the development of a bioassay which enables the detection or toxic effects of heavy metal ions to a bacterium. Escherichia coli. Inhibition effects of the metals on growth rates of the bacterium were studied in the absence or presence of fulvic acid. This method does not clearly differentiate among metals. but dues detect overall AGB inhibition rate (toxicity) for 5 different heavy metals. The toxicity of the metals in the absence of fulvic acid in the same testing conditions was significantly increased in following order: Hg
