Fig. 5. Species at Risk pesticides metric (SPEARpesticides) versus the sum of toxic units for fipronil(s) (ΣTUFipronils) at streams sampled in five regional studies (36–40).

Fig. 5

Fipronil toxic units are the measured fipronil(s) concentrations divided by compound-specific HC5 values determined from SSDs (see Fig. 4) derived from the mesocosm experiment. Black lines, generalized additive model (GAM). Red dashed lines, 95% CIs of GAM. ΣTUFipronils are transformed as log10(ΣTUFipronils + 1).
