Book Description
The individual toxic contributions of poisons were summed, and the additive toxicity was defined by a linear index for two chemicals in combination. This index expresses the toxicity quantitatively: zero indicates additive toxicity, negative values indicate less than additive toxicity, and positive values indicate greater than additive toxicity. We selected examples from the literature and conducted tests in the laboratory to assess the additive toxicity of selected chemical mixtures to fish.
