The general population is exposed to glyphosate through food, water and air
• Long-term use of glyphosate worldwide has led to rising human exposure, mainly through contaminated food consumption (Myers et al., 2016).
• The presence of glyphosate in food is due to the high thermal stability of its molecule, which elicit their accumulation in crops and thus their easy transfer to plant-based foods (Narimani and Da Silva,
2020)
• Numerous environmental analysis suggest that glyphosate detection is highly frequent in ground and surface water (Poiger et al., 2017; Rendon-Von Osten and Dzul-Caamal, 2017; Struger et al., 2015).
• A 2020 US government report found glyphosate in 66 of 70 US streams and rivers.
• Air samples taken from a region in France found glyphosate levels with a 7% of detection frequency, ranging from 0% to 23% in the different locations analyzed and a maximum concentration of 1.04 ng/m3 (Ravier et al., 2019).
• A study from Brazil, reported high glyphosate levels in all air samples evaluated, with values between 0.002 and 0.144 mg/m3 (mean of 0.055 mg/m3 ) in rural zones, while in urban zones ranged from
0.009 to 2.576 mg/m3 (mean of 1.006 mg/m3 ) (Maria et al., 2019).
