“…Despite its reputation of being safe, glyphosate can contaminate soil and water, leading to cascading effects on non-target organisms (Helander et al 2012). Toxic effects of glyphosate have been reported for a wide range of organisms (Gill et al 2018); for example, it was found to cause behavioral and physiological alterations in vertebrate (Avigliano et al 2014;Navarro-Martín et al 2014;Uren Webster et al 2014;Hansen and Roslev 2016) and invertebrate species (Schneider et al 2009;Balbuena et al 2015;Xu et al 2017;Blot et al 2019). We also have evidence of genotoxicity of this chemical; for instance, in human lymphocytes it was found to increase the frequency of micronuclei (MNi) (Santovito et al 2018), whereas other forms of DNA damage have been described in different cell types (Monroy et al 2005;Mañas et al 2009;Koller et al 2012).…”

Lycaena dispar Hawort (Lepidoptera: Lycaenidae), a protected butterfly, is declining in Europe, but it thrives in rice fields in northern Italy. Here, agrochemical usage could threaten its long-term survival. We investigated, by micronucleus (MN) assay, the genotoxic effect of glyphosate, a common herbicide, on L. dispar larvae. Micronuclei (MNi) are DNA fragments separated from the main nucleus and represent the result of genomic damage that has been transmitted to daughter cells. In a control/treatment experiment, we extracted epithelial cells from last-instar larvae fed with Rumex spp. plants sprayed with a solution containing 3.6 g/L of glyphosate, and from larvae fed with unsprayed plants. MNi and other chromosomal aberrations—nuclear buds (NBUDs) and bi-nucleated cells—were then scored in 1000 cells/subject. Significant differences were found between glyphosate-exposed and control groups in terms of MNi and total genomic damage, but not in terms of NBUDs or bi-nucleated cells. We reported a possible genomic damage induced by glyphosate on larvae of L. dispar. For the first time, a MN assay was used in order to evaluate the genomic damage on a phytophagous invertebrate at the larval stage. Increased levels of MNi reflect a condition of genomic instability that can result in reduced vitality and in an increased risk of local extinction. Therefore, farmland management compatible with wildlife conservation is needed.

“…It affected hemocyte parameters and acetylcholinesterase (AChE) activity, but not antioxidant enzyme activities in mussel Mytilus galloprovincialis (Matozzo et al, 2018) with disruption of key biological processes including energy metabolism, Ca 2+ homeostasis and endoplasmic reticulum stress response, as well as cell signaling identified by transcriptome analysis (Milan et al, 2018). Glyphosate exerted acute toxicity on the invasive snail Pomacea canaliculata with a 96-h LC 50 value of 175 mg/l, overly high for control purposes, but indicating oxidative stress, enhanced overall metabolic rate and altered catabolism from protein to carbohydrate/lipid mode (Xu et al, 2017).…”

“…Roundup® and other glyphosatebased formulations are used extensively in agricultural areas as well as for weed control in aquatic areas [32]. Numerous aquatic toxicity studies have been performed with GBHs [33][34][35]. The toxic effects of the active ingredient (glyphosate) and commercial formulations have been previously compared.…”

In the present study, we determined the 24, 48, 72, and 96 h LC50 values for a glyphosatebased commercial herbicide (GBH) for the aquatic snail Melanopsis praemorsa. We examined subacute toxicity responses from M. praemorsa after 30-day exposure to 1/10, 1/5, and 1/2 of the 96 h LC50 value using several biochemical markers. Glutathione reductase (GR) and glutathione S-transferase (GST) activities were significantly inhibited when compared to control after 4 days of GBH exposure. On the twentieth day of exposure, GST and GR activities were inhibited in organisms exposed to both LC50/10 and LC50/5 compared to control. These results showed that chronic GBH exposure inhibited GST, an important detoxifying enzyme. GR, an important oxidative stress marker, was likely inhibited as a result of inhibition of the detoxification mechanism.
