“…Recent evidence suggests that some zooplankton species experience reductions in survival and reproduction well below 120 mg Cl − /L. For instance, Valleau et al 34 found that the 14-d LC 50 for two freshwater zooplankton, Bosmina longirostris and Chydorus brevilabris , from soft water lakes ([Ca 2+ ] = 1.3–1.4 mg/L, 1.7–3.5 mg CaCO 3 /L) were 24 mg Cl − /L and 60 mg Cl − /L, respectively. Arnott et al 17 found that increased mortality and reduced reproduction can occur at 4–40 mg Cl − /L in Canadian Shield lakes, perhaps due to very low concentrations of Ca 2+ and other ions like Mg 2+ .…”

“…However, our soft-water treatment was perhaps not low enough to detect an interaction with road salt. Characteristics of the soft-water FLAMES medium used in studies where the impacts of road salt occur at very low Cl − concentrations—such as Valleau et al 34 —has 9.41 mg CaCO 3 /L, 2.54 mg Ca 2+ /L, and 0.75 mg Mg 2+ /L 35 . These concentrations are lower than our soft-water treatment of 20 mg CaCO 3 /L.…”

Rising salinity from road deicing salts threatens the survival and reproduction of freshwater organisms. We conducted two experiments to address how Daphnia pulex survival and reproduction were affected by road salt concentration (control, 120, 640 and 1200 mg Cl−/L) crossed with three concentrations of water hardness (20, 97, 185 mg CaCO3 /L). D. pulex survival was poor in our hard water treatment in both experiments (185 mg CaCO3 /L), potentially indicating a low tolerance to hard water for the strain used in our experiments. With the remaining two hardness treatments (20 and 97 mg CaCO3 /L), we found no evidence of an interactive effect between salt concentration and water hardness on D. pulex survival. In our population-level experiment, D. pulex survival was reduced by > 60% at 120 mg Cl−/L compared to the control. In the individual experiment, survival was similar between the control and 120 mg Cl−/L, but ≤ 40% of individuals survived in 640 and 1200 mg Cl−/L. For the surviving individuals across all treatments, the number of offspring produced per individual declined with increasing Cl− concentration and in hard water. Our results indicate that current Cl− thresholds may not protect some zooplankton and reduced food availability per capita may enhance the negative impacts of road salt.

Daphnia spinulata Birabén, 1917 is an endemic cladoceran species, frequent in the zooplankton communities of the shallow lakes of the Pampean region of Argentina. These lakes have varying salinity levels and, being located in agricultural areas, are frequently subject to pesticide pollution. This study aimed to determine the effects of the herbicide glyphosate (Panzer Gold®) in combination with different salinity levels on the biological parameters of D. spinulata and its recovery ability after a short exposure. Three types of assays were performed: an acute toxicity test, a chronic assessment to determine survival, growth and reproduction, and recovery assays under optimal salinity conditions (1 g L − 1 ). The LC 50 -48h of glyphosate was 7.5 mg L − 1 (3. 15-11.72). Longevity and the number of offspring and clutches were signi cantly reduced by glyphosate and high salinity exposure, whether in isolation or combined. The timing of the rst offspring did not recover after glyphosate exposure. Our results reveal that D. spinulata is sensitive to the herbicide, which causes stronger negative effects in conditions of higher salinity. Further research is needed to shed further light on the sensitivity of this cladoceran to glyphosate and its variability under other interactive stress factors.
