“…In addition, the toxicity of glyphosate has been studied in some non-target freshwater organisms (both non-photosynthetic and photosynthetic) such as cnidarians, insects, fish, amphibians, algae, and vascular plants. These reports indicate a toxicity pattern with higher toxicity in low-complexity organisms and photosynthetic organisms, and low toxicity in fish and amphibians, e.g., [9][10][11][12][13][14][15], resumed on Supplementary Table S1.…”

Glyphosate and Roundup® Ready Effects in Hydra viridissima: New Data in an Old Issue

Herbicides are used worldwide to protect agricultural crops, glyphosate being among the most frequently applied. In 2019 the European Commission approved the use of this herbicide for another 5 years and is now preparing its re-authorization for marketing. It is known that glyphosate (an active ingredient—AI) is usually less toxic than its commercial formulations, which may be related to adjuvants presents in such formulas. In this context, this work aimed to evaluate and compare the effects of glyphosate, as the commercial formulation Roundup® Ready (RR), and the AI in the Hydra viridissima life cycle, namely: mortality, morphology, feeding, reproduction, and regeneration. To attain this goal, H. viridissima was exposed to an environmentally relevant concentration of glyphosate (5.2 mg AI/L, both for RR and the AI) and to its culture medium (control). The mortality was lower than 0.03% for both RR and AI. Regarding morphological alterations, these were more severe on organisms exposed to RR, while a high recovery capacity in hydras exposed to AI was observed. No hydra was able to completely regenerate its body parts when exposed to RR, while 95% of the organisms exposed to AI were able to regenerate completely. The feeding rates of hydras exposed to RR decreased by from ~20% to ~50% compared to AI. As for reproduction, hydras exposed to RR released ~70% less buds than those exposed to AI. These timely results suggest that adjuvants present in the commercial formulation of glyphosate may cause higher toxicity to biota than the AI at environmentally relevant concentrations. Though the commercial formulation exerted higher toxicity in hydra, the effects AI induced in the morphology of the hydra cannot be disregarded, suggesting that a deeper understanding on the long-term toxicity of this AI is still needed to further support the decision on its marketing authorization and environmentally safe use.

“…Information available in the literature demonstrate that glyphosate (as active ingredient or commercial formulation) and AMPA affect various biological parameters in non-target aquatic organisms, such as fish 13,14 , amphibians 15 , crustacea 16–18 and molluscs 19–23 . In two distinct experiments, we have recently demonstrated that exposure to glyphosate (10, 100 and 1000 µg/L) and AMPA (1, 10 and 100 µg/L) affected biomarker responses in Mytilus galloprovincialis 24,25 , sometimes with similar effects, sometimes with opposing effects.…”

Assessment of the effects of chemical mixtures is a very important objective of the ecotoxicological risk assessment. This study was aimed at evaluating for the first time the effects of a mixture of glyphosate and its main breakdown product aminomethylphosphonic acid (AMPA) on various biomarkers in the mussel Mytilus galloprovincialis. Mussels were exposed for 7, 14 and 21 days to either 100 µg/L of glyphosate, 100 µg/L of AMPA or a mixture of both (100 + 100 µg/L). Various haemocyte parameters, such as total haemocyte counts, haemocyte diameter and volume, haemocyte proliferation, haemolymph lactate dehydrogenase activity and haemocyte lysate acid phosphatase activities were measured. In addition, the effects of exposure on the activity of antioxidant enzymes, acetylcholinesterase and glutathione-S-transferase were evaluated in gills and digestive gland from mussels. On the whole, this study demonstrated that the variables considered in the experimental plan, namely treatment, exposure time and their interaction, affect significantly biomarker responses in M. galloprovincialis. The effects of the mixture were comparable to those of the individual compounds, whereas their synergistic effects were occasionally observed, under the experimental conditions tested at least.

Gammarids are amphipods found worldwide distributed in fresh and marine waters. They play an important role in aquatic ecosystems and are well established sentinel species in ecotoxicology. In this study, we sequenced the transcriptomes of a male individual and a female individual for seven different taxonomic groups belonging to the two genera Gammarus and Echinogammarus: Gammarus fossarum A, G. fossarum B, G. fossarum C, Gammarus wautieri, Gammarus pulex, Echinogammarus berilloni, and Echinogammarus marinus. These taxa were chosen to explore the molecular diversity of transcribed genes of genotyped individuals from these groups. Transcriptomes were de novo assembled and annotated. High-quality assembly was confirmed by BUSCO comparison against the Arthropod dataset. The 14 RNA-Seq-derived protein sequence databases proposed here will be a significant resource for proteogenomics studies of these ecotoxicologically relevant non-model organisms. These transcriptomes represent reliable reference sequences for whole-transcriptome and proteome studies on other gammarids, for primer design to clone specific genes or monitor their specific expression, and for analyses of molecular differences between gammarid species.
