From: A critical examination of the protection level for primary producers in the first tier of the aquatic risk assessment for plant protection products

Fig. 5

Protection level indicated by the cumulative distribution of the first tier regulatory acceptable concentrations versus the higher tier regulatory acceptable concentrations (i.e., Tier-1 RAC/Tier-3 RAC ratios) of various active substances. X-axis: Tier-1 RAC/Tier-3 RAC ratios with Tier-1 RAC based on different types of endpoints (A lowest endpoint Eb/yC50; B growth rate endpoint ErC50) and an assessment factor of 10. Y-axis: percentage of active substances with first tier RACs being lower than higher tier RACs, i.e., fulfilling the minimum suitable protection level, as set in the specific protection goals
