Division 8.2.7 Effects on aquatic macrophytes

A test shall be provided establishing EC₁₀, EC₂₀, EC₅₀ and corresponding NOEC values for Lemna species growth rate and yield, based on measurements of number of fronds and at least one additional measurement variable (dry weight, fresh weight or frond area).

For other species of aquatic macrophytes, a test shall provide sufficient information to evaluate impact on aquatic plants and provide EC₁₀, EC₂₀, EC₅₀ and corresponding NOEC values based on measurement of appropriate biomass parameters.
