As Paracelsus proposed centuries ago, dose differentiates whether a substance will be a remedy or a poison. A xenobiotic in small amounts may be non-toxic and even beneficial but when the dose is increased, toxic and lethal effects may result.

The interactive effects between copper and zinc and between lead and zinc were synergistic, while the interactive effect between copper and lead on the bioluminescence of V. fischeri was additive. The presence of HAs caused relatively high toxicity reduction in the binary mixtures of zinc and copper or zinc and lead, while the toxicity reduction in the case of the binary mixture of copper and lead was negligible. The investigation of the joint solubility, bioavailability, and toxicity of heavy metals toxic effects of chemicals in a mixture is generally based are dependent on various physicochemical parameters on comparison of the actual toxic effect of the mixture such as pH, hardness, interactive effects, and presence of with the theoretically expected toxic effect deduced by a natural organic matter (Janssen et al., 2003; Heijerick et statistical model, using the toxic effects of the individual al The independent action model was used in order to predict the theoretically expected effect. The interactive effects were mostly antagonistic or additive, while in few cases (interactive effects of metalaxyl-M and copper on V. fischeri) a synergistic mode of action was observed for some concentration combinations. Experiments showed that interactive effects of chemicals may vary depending on the test species used as well as on the chemicals and their respective concentrations. In the plain of Thessaloniki, in Northern Greece, significant quantities of these agrochemicals have been found in water resources and soil.
on Aquatic Organisms. Abstract : The effects of three common agrochemicals, lindane, methyl parathion and atrazine, on crustaceanDaphnia magna, algaSelenastrum capricornutumand marine bacteriumVibrio fischeriwere investigated in this study. The toxic and interactive toxic effects of two agrochemicals (fosthiazate and metalaxyl-M) and copper were investigated in this study on the photobacterium Vibrio fischeri.
The purpose of this study is to find the relationship between an interactive toxic effect and distribution of heavy metals in algal cells.
presence of HAs reduced both the toxicity of Cu and Zn Kungolos, A., Hadjispyrou, S., Petala, M., Tsiridis, V., Samaras, P., applied together and that of Pb and Zn applied together.

Phylogenomic Mining Frontiers | Interactive Effects of Mycorrhizae, Soil Costs and benefits of Interactive toxic effects of heavy metals and humic acids on Vibrio fischeri. The effect of humic acids (HAs) on the toxicity of copper, zinc, and lead was investigated using the photobacterium Vibrio fischeri (Microtox test) as a test organism. The effects of HAs on metal toxicity were evaluated as functions of time and concentration in pure compound solutions. The interactive effects were mostly antagonistic or additive, while in few cases (interactive effects of metalaxyl-M and copper on V. fischeri) a synergistic mode of action was observed for some concentration combinations.
