“…Data about AMPA toxicity in aquatic systems are scarce and contradictory [32,33]. A literature review concerning the impact of AMPA on aquatic organisms reported serious impacts on the European eel (Anguilla anguilla), zebrafish (Danio rerio), guppies (Poecilia reticulata), Mediterranean mussels (Mytilus galloprovincialis), and toads (Bufo spinosus) [12] but another study found that AMPA was the least toxic of the chemicals associated with glyphosate-based formulations to zebrafish [33].…”

“…AMPA exposure causes genotoxicity and immunotoxicity in fish, adverse changes in hemolymph parameters, effects on mussels' antioxidant enzymes, as well as developmental delays and affecting the survival of tadpoles [12]. Also, AMPA can induce sublethal responses in mosquito (Aedes aegypti) larvae during acute exposures [32]. However, under environmentally realistic concentrations, AMPA was not toxic to aquatic vertebrates and invertebrates [34,35].…”

To establish meaningful policy directives for sustainable agrochemical use, we require baseline knowledge of the impacts of agrochemicals on non-target organisms. The widespread use of the herbicide glyphosate has resulted in the global presence of its metabolite, aminomethylphosphonic acid (AMPA). AMPA is commonly found in water bodies, including freshwater systems. We investigated the effects of AMPA exposure on the survivorship, regenerative abilities, and locomotion of the brown planarian (Girardia tigrina), a water-dwelling flatworm commonly found in freshwater ecosystems. In a series of experiments, we bisected and then exposed planarians to realistic field doses of AMPA for seven days and then fourteen days. For the 14-day experiment, we exposed planarians to two concentrations consistent with the high and low ranges of concentrations observed in water systems. Compared to the control group, we found that planarians exposed to AMPA for fourteen days (un-bisected for the first seven days and recovering from bisection for the subsequent seven) exhibited slower regeneration from the tail segment. Our findings highlight the potential ecological impacts of AMPA contamination on planarian populations. Quantifying the effects of AMPA exposure on planarians contributes to our understanding of the ecological consequences of our current and common agricultural practices on our freshwater ecosystems.

The widespread use of the herbicide glyphosate has resulted in the global presence of its degra-dation product, aminomethylphosphonic acid (AMPA), in the global environment. AMPA is commonly found in water bodies, including freshwater systems. We investigated the effects of chronic and acute AMPA exposure on the survivorship, regenerative abilities, and locomotion of the brown planarian (Girardia tigrina), a water-dwelling flatworm commonly found in freshwa-ter ecosystems. We exposed planarians to two concentrations of AMPA, consistent with the high and low ranges of concentrations observed in US water systems. We measured endpoints includ-ing survivorship, regenerative abilities of head and tail segments, eyespot regeneration, and swimming speed. Compared to the control group, we found that planarians chronically exposed to AMPA exhibited (1) modestly reduced survivorship while regenerating and (2) slower regen-eration from the tail segment. No significant differences were observed in intact body growth during chronic exposure. Our findings highlight the potential ecological impacts of AMPA con-tamination on planarian populations. Understanding the effects of AMPA exposure on planarians contributes to our understanding of the ecological consequences of glyphosate use in freshwater ecosystems.

“…Aquatic plants are in frequent contact with this compound, resulting in chronic exposure and leading to an accumulation process. Due to the ability of the genus Salvinia to remove a variety of organic pollutants (Mendes et al 2021;Gomes et al 2023), the aim of this study is to evaluate the phytotoxicity of IVM in Salvinia minima and the accumulation process of the drug performed by bioassays.…”

Ivermectin (IVM) is a macrocyclic lactone widely used to control endo- and ectoparasites in livestock. After administration, it is partially metabolized by the animal and therefore excreted in its original form. IVM can enter water bodies through groundwater, runoff, soil erosion, and direct deposition. Once in aquatic and wetland environments, due to its chemical characteristics, can persist for a long time, increasing its environmental risk. Macrophytes are in frequent contact with this drug, resulting in chronic exposure and leading to an accumulation process. The objective of this study is to evaluate the uptake of IVM in S. minima, and its phytotoxicity potential. Bioassays were performed to expose S. minima to different concentrations of IVM, 5 mg/L, 10 mg/L, and 30 mg/L. After 10 days, the accumulation of the compound in fronds, roots, and effluent was measured. Morphological parameters and photosynthetic pigments were evaluated. IVM was found in fronds and roots of S. minima after exposure. The percentage of remotion of the drug in effluent were significantly, up to 66%. The highest concentration evaluated showed phytotoxic effects. S. minima proved to be a promising species for IVM removal processes and early toxicity marker physiological parameters, especially in wetlands subject to intensive livestock farming activities. Of interest for its applicability in wetlands subjected to intensive livestock farming.
