“…Although P. pilsbryi is widely found throughout the northern United States and southern Canada, it is much less frequently studied compared with other gastropods, such as L. stagnalis . Recently, a number of studies have assessed the sensitivity of P. pilsbryi to contaminants of emerging concern such as novel formulations of glyphosate (Currie et al, 2015), neonicotinoid insecticides (Prosser et al, 2016), and dinonylnaphthalene sulfonic acids (Matten et al, 2020). Other than Osborne et al (2020), who reported only nominal exposure results for Cu, the authors are not aware of any other peer‐reviewed studies regarding the toxicity of a suite of metals to P. pilsbryi across multiple life stages.…”

Early life stages are commonly thought to be highly sensitive to environmental contaminants and may offer insight into the future health of a population. Despite the importance of studying early life stages, very few standard protocols for benthic invertebrates commonly used in ecotoxicological assessments measure developmental endpoints. The goal of the present study was to develop and optimize a robust standard protocol for studying embryonic endpoints in freshwater gastropods. The developed method was then used to characterize the sensitivity of four embryonic endpoints (viability, hatching, deformities, and biomass production), in conjunction with juvenile and adult mortality, for the snail Planorbella pilsbryi exposed to three metals (copper [Cu], cadmium [Cd], and nickel [Ni]). Biomass production was typically the most sensitive endpoint but was relatively variable, while embryo hatching was slightly less sensitive but highly consistent for all three metals. However, no single embryonic endpoint was consistently the most sensitive, which demonstrates the importance of assessing a broad range of endpoints and life stages in ecotoxicological risk assessment. Interestingly, the embryonic life stage of P. pilsbryi was considerably less sensitive to Cu exposure compared with juvenile and adult mortality. However, for Cd exposure, embryonic endpoints were the most sensitive, and for Ni exposure, embryonic endpoints were similar in sensitivity to juvenile and adult mortality. The present study has valuable applications in conducting developmental toxicity research with organisms lacking standardized testing protocol as well as future applications in multigenerational and in silico toxicity research.
