Interspecies Correlation Estimation

Species Sensitivity Distributions

  • Species sensitivity distributions (SSDs) are cumulative probability distributions of toxicity values for multiple species. For environmental risk assessment, the chemical concentration that may be used as a hazard level can be extrapolated from an SSD using a specified percentile of the distribution.

    This SSD module generates a distribution for a chemical from Web-ICE estimated toxicity values and the entered toxicity of up to 25 surrogate species.
