Species sensitivity distribution definition

Figure 9.3 Estimation of toxicity for the hypothetical most sensitive species. Based on the assumption of log-normally distributed effect concentrations causing a definite toxic response (e.g. LCgo) with the different species of the habitat (right curve), the respective impact level for the most sensitive species can be extrapolated provided that the total number of species in the community is known (left curve).
