SL236: Aquatic Toxicology Notes: Predicting the Fate and Effects of Aquatic and Ditchbank Herbicides

Figure 4. Example of a species sensitivity distribution. Species sensitivity decreases as concentration increases. The vertical line on the plot represents a hypothetical concentration in the water following treatment. Organisms appearing on the left-side of that line would likely be affected by the herbicide, while those to the right would not.
