Protective effect of sonicated cashew apple bagasse (10, 100, and 1000 μg/mL) in Artemia salina instar II nauplii at 24 and 48 h of exposure. No significant protective effect was noted in fresh (A), 75 W/cm² (B), 266 W/cm² (C), or 373 W/cm² (D) sonicated cashew bagasse at 24 or 48 h of exposure. Negative control (artificial seawater) did not cause significant death of nauplii. Conversely, positive control (K₂Cr₂O₇ 0.5 M) was lethal for 100% of individuals, including 24 h of exposure. H₂O₂ at LC₅₀ (127.45 mM) cause death of nearly 50% of individuals at 24 h exposure and death of nearly all nauplii at 48 h of exposure.
