Species Sensitivity Distribution Generator

Download the SSD_Generator_V1.xlt (2.8MB, .xlt) to calculate and plot the proportion of species affected at different levels of exposure in laboratory toxicity tests. See the SSD methods page for further details on the use of SSD plots in causal analysis. EPA (2005) provides more detail on selecting data for SSDs and the method used in generating them.

This is a Microsoft Excel template that depends on macros for operation, so you must select “enable macros” when you open the template.
