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

Glyphosate, one of the most widely used agricultural chemicals globally, is present in the Venice Lagoon primarily due to external inputs from river inlets and local agricultural activities. A study analyzing water, suspended particulate matter, and sediment samples from seven sites between 2019 and 2021 found maximum glyphosate concentrations of 260 ng/L in lagoon water, 7 ng/L in suspended particulate matter, and 15 ng/g in sediment, with spatial and temporal variations. The research employed ion chromatography coupled with tandem mass spectrometry to assess glyphosate levels, providing insights into its distribution and sources in this unique ecosystem.
