ABSTRACT

The combined effect of sodium nitrate (I) and cadmium chloride (II) on aquatic organisms was tested by means of a bioassay with luminescent bacteria. The results showed that the observed effect of (I) and (II) acting in combination is weaker than their expected additive effect. Hence, in setting standards for concentrations of nitrates in water, it is necessary to take into account the principle of additivity in the combined action of toxicants.
