Assessing glyphosate in water, marine particulate matter, and sediments in the Lagoon of Venice

Abstract: Lagoon water, suspended particulate matter, and sediment samples from seven sites at Lagoon of Venice were collected from 2019 to 2021 in order to study the presence of the herbicide glyphosate (N-(phosphonomethyl)glycine), among the most widely used agricultural chemicals worldwide, but its occurrence in lagoon water environment has not been deeply investigated. The sites were selected considering a supposed diversity of inputs and of pollution levels. An analytical method based on ion chromatography coupled … Show more

“…A sediment core in a French vineyard catchment had AMPA residues of ca 300 μg kg −1 while glyphosate could not be detected, 69 which is likely given that water was used as extraction medium in that study. A recent study reported glyphosate residues of 15 μg kg −1 in sediments of the Lagoon of Venice in 2021 40 . The poor matrix tolerance of the separation technique (ion chromatography) used in their study restricted the extraction medium to ultrapure water; and co‐extracted salt matrix suppressed the detection of AMPA.…”

“…The established method demonstrates a 30 fold increase in sensitivity compared to previous studies. 21 Previous analytical methods developed to measure GLY, GLU, and AMPA in diverse matrices [37][38][39] used isotope labeled internal standards (i.e. (glyphosate-2-13C, 15 N), (AMPA-13C, 15 N), and D3glufosinate) for efficient quantication and derivatization.…”

“…With increased introduction of glyphosate‐resistant genetically modified crops, glyphosate was widely used in agricultural production (Benbrook, 2016; Duck, 2005), leaving glyphosate residues in soil, water and various organisms (Battaglin et al, 2014; Chang et al, 2011; Pérez et al, 2011). Studies showed that the highest detected concentration of glyphosate in Venetian lagoon water was 260 ng/L (Feltracco et al, 2021); the highest level in drinking water in the United States was 700 μg/L (Mertens et al,2018); and the accumulated level in fish ponds in rural China was 812 μg/L (Zhang et al, 2014). The average urinary level in exposed people was 1.35–3.2 μg/L (Connolly et al, 2020).…”
