Division 8.2 Effects on aquatic organisms

Reports of the tests referred to in points 8.2.1, 8.2.4 and 8.2.6 shall be submitted for every active substance and supported with analytical data on concentrations of the substance in the test media.

When aquatic toxicity studies are conducted with a poorly soluble substance, limit concentrations lower than 100 mg substance/L may be acceptable, however precipitation of the substance in the test medium shall be avoided and a solubiliser, auxiliary solvent or dispersing agent shall be used when appropriate. Testing using the plant protection product may be required by the F1... competent authorities if no biological effects occur at the solubility limit of the active substance.

Toxicity endpoints (such as LC₅₀, EC₁₀, EC₂₀, EC₅₀ and NOEC) shall be calculated on the basis of nominal or mean/initial measured concentrations.
