“…Although species composition is known to evolve rapidly over time and in the presence of stressors, biofilms have been shown to provide a robust signal in terms of metal accumulation [19]. Biofilms also provide the advantage of being present in the surface waters (streams, rivers, or lakes) of even the most contaminated ecosystems, where they have been shown to respond to a large array of both organic and inorganic contaminants [20][21][22][23]. Biomonitoring can also offer additional information than water sampling techniques alone.…”

“…Lifecycle rearing experiments with As-treated periphyton [11] suggest that N. triangulifer is a poor As accumulator, with larval As concentrations likely driven by gut contents. Additional research has shown that efflux of As in a variety of aquatic taxa is quite rapid, which may also account for the lack of accumulation in N. triangulifer [24]. In our experiment, 13 Figure 2.…”

“…Arsenic may also be introduced to the lake sediments from the watershed in association with aquatic and terrestrialderived OM. Dissolved As may bioaccumulate in aquatic organisms living in the water column, such as phytoplankton and zooplankton, to concentrations orders of magnitude higher than those in ambient waters (Eisler, 1988;Hellweger et al, 2003;Lopez et al, 2017). Abundant labile OM is observed both petrographically (alginate) and geochemically (S1 and S2) in the near-surface sediment of Bulldog and Powder Mag lakes, suggesting that aquatic organisms are accumulating As and delivering it to near-surface sediment (Fig.…”
