Assessing multigenerational effects of prednisolone to the freshwater snail, Physa acuta (Gastropoda: Physidae)

Prednisolone (PDS), a potent synthetic glucocorticoid is widely prescribed for its exceptional anti-inflammatory properties. Several studies have detected the environmental presence of PDS in water bodies which has led to an ecological concern for its toxicity to non-target aquatic biota. The present study investigated the effects of exposure to PDS on different life-cycle stages and generations of the freshwater snail, Physa acuta. This continuous exposure over a period of multiple generations resulted in generational impairments at measured endpoints. LOEC values (p
