Abstract Glyphosate’s primary metabolite, aminomethylphosphonic acid (AMPA), is the most detected pollutant in surface waters. Recent studies have raised concerns about its toxicity, yet underlying mechanisms remain poorly understood. A disruption of gut microbiome, which plays a crucial role host health, could mediate adverse effects. We investigated impact AMPA exposure on microbiome spined toad tadpoles ( Bufo spinosus ). hypothesized that alter microbiota composition and these effects depend source. exposed to minute concentrations analyzed their faecal using 16S rRNA gene sequencing as proxy microbiota. decreased bacterial biomass affected community tadpole’s faeces. Furthermore, we observed interactions between maternal body condition Bacteroidota Actinobacteriota phyla abundances. This suggests effect early-life microbial colonizers influence response AMPA. These findings highlight importance considering when studying environmental contaminants. Further research needed elucidate long-term implications this alteration for amphibian health.

Abstract The historical perspective on the rapid biodegradation of pesticides as a mitigating factor in environmental risk assessment is reexamined through example glyphosate and its implications for freshwater biodiversity. Commonly employed standardized methods by national agencies assessing predominantly rely single-species tests, overlooking intricate nature ecosystems. Glyphosate, one most widely used marketed purported biodegradability, often perceived relatively innocuous. However, degradation releases phosphorus into environment, inducing trophic state shift water systems towards more eutrophic conditions, consequently affecting quality. These findings highlight cascading ecological repercussions biodegradation, driving proliferation specific aquatic organisms, such picocyanobacteria metaphyton, resulting alteration ecosystem structure dynamics. study explores challenges posed commercial pesticide formulations investigates consequences interactions with anthropogenic factors. A case point interaction invasive mussel Limnoperna fortunei , exacerbating overall scenario. framework analyzed conventional notion that inherently neutral or positive event. results underscore necessity reassessing role itself impact assessments pesticides.

Glyphosate is the most used herbicide globally, but little known of its prevalence in Australian environment or behaviour during wastewater treatment. This study examined concentration glyphosate and primary biodegradation product, aminomethylphosphonic acid (AMPA), influent effluent from 22 treatment plants (WWTPs) to inform exposure risks. was detected all WWTP samples, with concentrations ranging 0.37 370 μg/L (mean: ± 76 μg/L). In treated effluent, found 82 % samples
