“…Gawad (2018) found lead LC 50 concentrations of 18 mg/L for Thodoxus niloticus after 96 h of exposure. As the exposure period for our study was comparatively long at 7 days, P. duryi appears to be less sensitive to both cadmium and lead, a hypothesis that is supported by previous findings in a study that observed bioconcentration factors 177,550 times higher in adult P. duryi exposed to coal ash leachates compared with control organisms (Frankel et al, 2023). Such findings provide further insight into the potential for these metals to both bioaccumulate and bio-magnify across food webs in contaminated environments and suggest that further research is needed to fully understand the ability of these metals to accumulate and partition in various tissues of this species.…”

“…Concentrations for trace metal standards for Cd, Pb, and As were based on methods described in Frankel et al (2023). Samples of adult and embryonic treatment solutions for each metal were examined in triplicate using ICP‐OES at wavelengths selected to reduce the potential for spectral interference (i.e., 228.8 nm for Cd, 193.8 nm for As, and 217.0 nm for Pb).…”

“…Adult locomotor behavior was assessed on Days 1 and 7 in conjunction with the 7‐day adult viability assay using methods adapted from Frankel et al (2023). Snails were removed from their beakers and placed into a 150‐mm petri dish filled with 100 mL of their respective treatment solution ( n = 6).…”

“…Planorbella duryi is a hermaphroditic freshwater snail species commonly found in U.S. river systems (USGS, 2015). This widespread distribution combined with a prolific reproduction strategy renders them an ideal subject for laboratory studies, as they are easy to culture, and clear egg clutches allow embryonic development to be easily tracked (Eissa et al, 2022;Frankel et al, 2020Frankel et al, , 2023, Figure 1).…”

Trace metal contamination is a widespread issue due to its many natural and anthropogenic sources and known carcinogenic, teratogenic, and reproductive effects. As previous invertebrate trace metal research has primarily focused on model species (Daphnia magna, Chironomidae, etc.), our understanding of effects on non‐model invertebrate species remains relatively poor. As such, this study assessed the exposure effects of cadmium, arsenic, and lead on viability, locomotor behavior, and embryonic development of the Seminole ramshorn snail (Planorbella duryi). Exposure treatments of CdCl2, Na2HAsO4 • 7H2O, or Pb (NO3)2 were prepared at concentrations of 0, 0.01, 0.1, 1, and 10 mg/L and confirmed using inductively coupled plasma optical emission spectroscopy (ICP‐OES). Individual adult P. duryi were exposed for 7 days with viability assessed every 24 h, and locomotor behavior was accessed on Days 1 and 7 using ToxTrac v2.97 automated behavior software. Individual embryos from newly laid (<6 h old) embryonic clutches were exposed for 10 days, during which embryonic development stage was documented every 24 h. Based on our results, an additional follow‐up study for cadmium was conducted using a lower range of 0–0.1 mg/L to allow for the observation of sublethal endpoints. Adult lead and cadmium exposure resulted in significant mortality in the highest treatments (1 and 10 mg/L), dose‐dependent behavioral effects, and delayed embryonic development. Arsenic exposures resulted in little to no impacts for all assessed endpoints. Our results provide new insight into the sublethal impacts of these contaminants and highlight potential for behavior and embryonic development as useful tools for risk assessment.Practitioner Points The exposure effects of lead, cadmium, and arsenic on the viability, embryonic development, and locomotor behavior of a common freshwater snail species was investigated using environmentally relevant concentrations. The severity of impact differed for each trace metal, with cadmium being the most toxic and arsenic the least toxic at concentrations ranging from 0 to 10 mg/L. Embryonic development appeared to be the most sensitive endpoint of those tested in this study, suggesting that exposure may have prolonged effects that extend to population and community levels. The Seminole ramshorn snail serves as a sensitive alternative model species that can be used to assess the impacts of contaminants on freshwater invertebrates in future studies.
