“…The use of GBH intensified due to the emergence of herbicide-resistant weed species [ 1 ], and it is presently the most widely used herbicide in the world [ 2 ]. Consequently, it accumulates in different areas near its application site, polluting rivers and water sources [ 3 , 4 ]. Glyphosate has been detected in concentrations of about 0.70 µg mL −1 in different regions of the world [ 5 , 6 , 7 ], with a maximum peak of 5.15 µg mL −1 in accidental spills [ 8 , 9 ].…”

Inflammatory, Oxidative Stress, and Apoptosis Effects in Zebrafish Larvae after Rapid Exposure to a Commercial Glyphosate Formulation

et al. 2021

Glyphosate-based herbicides (GBH) are the most used herbicides in the world, carrying potentially adverse consequences to the environment and non-target species due to their massive and inadequate use. This study aimed to evaluate the effects of acute exposure to a commercial formulation of glyphosate, Roundup® Flex (RF), at environmentally relevant and higher concentrations in zebrafish larvae through the assessment of the inflammatory, oxidative stress and cell death response. Transgenic Tg(mpxGFP)i114 and wild-type (WT) zebrafish larvae (72 h post-fertilisation) were exposed to 1, 5, and 10 µg mL−1 of RF (based on the active ingredient concentration) for 4 h 30 min. A concentration of 2.5 µg mL−1 CuSO4 was used as a positive control. Copper sulphate exposure showed effectiveness in enhancing the inflammatory profile by increasing the number of neutrophils, nitric oxide (NO) levels, reactive oxygen species (ROS), and cell death. None of the RF concentrations tested showed changes in the number of neutrophils and NO. However, the concentration of 10 µg a.i. mL−1 was able to induce an increase in ROS levels and cell death. The activity of antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx)), the biotransformation activity, the levels of reduced (GSH) and oxidised (GSSG) glutathione, lipid peroxidation (LPO), lactate dehydrogenase (LDH), and acetylcholinesterase (AChE) were similar among groups. Overall, the evidence may suggest toxicological effects are dependent on the concentration of RF, although at concentrations that are not routinely detected in the environment. Additional studies are needed to better understand the underlying molecular mechanisms of this formulation.

“…As part of the systemic and broad-spectrum herbicides, glyphosate has the place of honor as the best-selling and most widely used herbicide globally [ 1 ]. It is estimated that over 800 million kilograms are sold annually with a value of over $6.5 billions dollars and it is usually applied on average 2–4 kg/ha [ 2 ], mainly in genetically modified crops resistant to this pesticide, such as soybeans, cotton and corn, among others, to eliminate unwanted herbs; their use is also common in native crops and gardening [ 3 ].…”

“…In 2019, the EPA proposed guidance to assess human exposure to chemicals in a non-occupational setting from inhalation, ingestion and dermal exposure in terms of site characteristics, population and period time [17]. (1) in plants (2), it can pass to different environments and expose the population through intake of contaminated food plants and by animals for human consumption that eat plants with glyphosate. A proportion of applied glyphosate reaches the soil (3) and through runoff and leaching (4) can reach surface water (5), such as rivers and lakes, and groundwater (6).…”

Glyphosate is a broad-spectrum herbicide widely used worldwide. Indeed, it is the herbicide most applied to all Mexican crops. Due to the overuse and poor disposal of the waste, this herbicide can reach the aquatic environments such as groundwater and surface water. Thus, there is a clear need to implement monitoring and surveillance programs for evaluating and controlling the exposure to this herbicide in rural populations. The goal of this study was to quantify the presence of glyphosate in different water bodies (groundwater, surface and drinking water) as well as to identify the uses and managements of water resources by rural communities to evaluate the potential human exposure to glyphosate in the Tenampulco region of the Mexican state of Puebla. Measurements were performed by a rapid and cost-effective ELISA-based method in groundwater and surface water from various sampling sites of the Tenampulco region. Glyphosate was detected in all groundwater samples to be below the maximum limit for glyphosate in water in Mexico. Nevertheless, these results indicate an exposure of glyphosate in these agricultural communities and the need to establish a monitoring program.

“…Additionally, glyphosate has been detected in urban surface waters in Australia. Okada et al (2020) identified the presence of glyphosate in 77% of urban stormwater wetlands and 79% of urban streams, demonstrating the potential for contamination of non-target environments. Herbicides are also one of the main types of pollutants affecting the Great Barrier Reef in Australia (Brodie et al, 2012).…”
