Potentiation of the toxic effects of some agents by transition metal ions, thereby making the process of nontoxic concentrations of other substances is an inter- ROS generation cyclic, continuing until the complete esting ecotoxicological phenomenon. The question as exhaustion of the reducer. Therefore, a mixture of a to how strong the potentiation effect can be is of partic- reducer and a transition metal (in nontoxic concentra- ular importance. From the ecotoxicological standpoint, tions) may induce the generation of ROS capable of it is obvious that, if substance A can signiﬁcantly damaging biological structures. We used ascorbic acid enhance the toxicity of substance B, it is more correct as a common and easily available natural reducer. to determine the former substance in parallel with the Thus, the purpose of this
