The effects of pharmaceuticals on a unionid mussel (Lampsilis siliquoidea): An examination of acute and chronic endpoints of toxicity across life stages

The toxicity and bioconcentration of 3 pharmaceuticals (amitriptyline, iopamidol, and sertraline) were examined using multiple life stages (larval, juvenile, and adult) of the unionid mussel Lampsilis siliquoidea. The endpoints examined varied with life stage but included survival, behavior (algal clearance rate, filtering frequency), and oxidative stress. Glochidia and juveniles were more sensitive than adult mussels. However, the compounds examined were not toxic at concentrations detected in the environment. The results suggest that glochidia toxicity could be a screening tool for rapidly assessing the toxicity of chemicals of concern to freshwater mussels. Results were published in a scientific article that can be found here: https://doi.org/10.1002/etc.3683
