From: Wastewater effluent affects behaviour and metabolomic endpoints in damselfly larvae

Activity measures. Mean ± SE (a) average speed (mm/s), (b) total time frozen (s) for damselfly larvae exposed to 0, 50, 75, and 100% effluent (E0, E50, E75, and E100, respectively). Statistically significant differences between control and exposed treatments after exposure are indicated with an asterisk (*p < 0.05).
