“…As concerns and studies on the behavior of glyphosate in plant and the environment are growing, several methodologies, including high-performance liquid chromatography (HPLC) (Khrolenko et al 2005;Araujo et al 2003), gas chromatography-mass spectrometry (GC-MS) (Kudzin et al 2002;Connolly et al 2020;Morgan et al 2019), LC-tandem mass spectrometry (LC-MS/MS) (Bressan et al 2021;Gormez et al 2021), liquid chromatography (LC) (Jost et al 2020;Thompson et al 2019), ion chromatography(IC) (Geerdink et al 2020;Schutze et al 2021), capillary electrophoresis (CE) (Wimmer et al 2020;Cao et al 2014), enzymelinked immunoassays (ELISA) (Byer et al 2008;El-Gendy et al 2018), fluorescence detection (Guan et al 2021;Sasaki et al 2020) and electrochemical luminescence methods (Habekost 2017;Sahoo et al 2018) have been developed to detect its residues. Although the sensitivity and specificity of these methods are relatively high, their shortcomings are also apparent.…”

Glyphosate　(GLYP)　is a broad-spectrum, non-selective, organic phosphine post emergence herbicide registered for use on many food and non-food field. Herein, we developed a biosensor (Mbs@dsDNA) based on carboxylated modified magnetic beads incubated with NH2-polyA and then hybridized with polyT-glyphosate aptamer and complementary DNA. Afterward, a quantitative detection method based on qPCR was established.　When the glyphosate aptamer on Mbs@dsDNA specifically recognized glyphosate, a complementary DNA is released and then enters the qPCR signal amplification process. The linear range of the method was 0.1-5 μg/mL, and the detection limit was set at 0.1 μg/mL. The recoveries in tap water were ranged from 103.4 ~ 104.9%, and the relative standard deviations (RSDs) were < 1%. The aptamer proposed in this study has a good potential for recognizing glyphosate. The detection method combined with qPCR might have a good application prospect in detecting and supervising other pesticide residues.

“…Different aqueous solutions such as NH 4 OH, NH 4 HCO 3 , (NH 4 ) 2 CO 3, or (NH 4 ) 2 SO 4 , could be possible but the presence of anions such as sulfate, carbonate, or hydroxyl could lead to Fe(III) precipitate interfering with ligand desorption. Moreover, ammonium ion can also suppress the broad peaks of GLYP and other analytes on chromatography coupled mass spectrometry analysis [48] . NH 4 OH sample solution was finally chosen to directly elute the 4 compounds after their preconcentration in the Chelex-100 resin in the Fe(III) form.…”

“…Therefore, it would be difficult to develop an analytical method to include all compounds. Indeed, most studies have used target methods based on a limited number of pesticides and TP/M [12][13][14]. Full-spectrum acquisition techniques could be a solution to this problem.…”

Pesticides have been used in large amounts around the world for decades and are responsible for environmental pollution and various adverse effects on human health. Analysis of untreated wastewater can deliver useful information on pesticides’ use in a particular area and allow the assessment of human exposure to certain substances. A wide-scope screening method, based on liquid chromatography coupled to quadrupole-time-of-flight mass spectrometry, was applied, using both target and suspect screening methodologies. Daily composite influent wastewater samples were collected for seven or eight consecutive days in Athens between 2014 and 2020 and analyzed for 756 pesticides, their environmental transformation products and their human metabolites. Forty pesticides were quantified at mean concentrations up to 4.9 µg/L (tralkoxydim). The most abundant class was fungicides followed by herbicides, insect repellents, insecticides and plant growth regulators. In addition, pesticide transformation products and/or metabolites were detected with high frequency, indicating that research should be focused on them. Human exposure was evaluated using the wastewater-based epidemiology (WBE) approach and 3-ethyl-carbamoyl benzoic acid and cis-1,2,3,6-tetrahydrophthalimide were proposed as potential WBE biomarkers. Wastewater analysis revealed the presence of unapproved pesticides and indicated that there is an urgent need to include more transformation products in target databases.
