SL368: Aquatic Toxicology Notes: Diquat

Figure 3. Species sensitivity distribution (plants, based on LOEC) for aquatic plants exposed to diquat. The straight line represents the model fit to all of the data (y = 9.9553ln(x) + 69.641; R2 = 0.8228). Maximum aqueous concentrations from the literature are higher than the most sensitive species, indicating a lack of a margin of safety for approximately 12% of species.
