Reproductive and developmental alterations in Biomphalaria alexandrina snails exposed to three phenolic compounds

The present work aims to assess the reprotoxicity in Biomphalaria alexandrina snails and developmental and hatchability alterations of their eggs after exposure to three phenolic compounds, viz., salicylic acid, benzoic acid and pyrogallol. The half lethal concentrations (LC50) of the three tested compounds were 574, 674 and 350 mg L−1, respectively after 24 h. The tested concentrations of all compounds showed a harmful effect on development and hatchability of eggs regardless of the age of embryos. Exposure of snails to sub-lethal concentrations of salicylic acid resulted in a significant reduction in their survival rate, and 1⁄2 LC50 of both benzoic acid and pyrogallol led to a sudden death of snails after the 1st week of the experiment. Therefore, the egg laying capacity showed a noticeable impairment throughout the whole experimental period. Moreover, the hermaphrodite glands of treated snails have mirrored the deleterious effects that occurred in the total reproductive rate
